1 Introduction

is study deals with the dynamic elastoplastic analysisconsidering a member buckling and the fuse-type con-nection consists of an aluminum ball joint an aluminumhub and a steel bolt A ductile elongation of the steel boltdue to a tensile stress is expected by avoiding the brittlecollapse in our previous paper [1ndash3] e study proposesa fuse-type connection by means of yield of the steel bolt dueto tension stress realized by the ductile failure collapsemechanism of the wall-type spatial structure

e seismic response characteristics of spatial structuressuch as roof and wall types depend on their form andsupport conditions and several reviews [4 5] and guidelines[6ndash13] quoting many studies have been published dependingon the performance of building structures Several perfor-mance prediction methods have been developed for thispurpose however the earthquake resistance capacity ofspatial structures requires the variation of the form and thesupport condition and it is very difficult to apply them towall-type spatial structures For the performance designseveral prediction methods such as a pushover analysis andan adaptive capacity spectrum method have been developedfor structures such as buildings and bridges [14ndash18]

e control of the dynamic collapse mechanism is alsoproposed to improve the earthquake resistance capacity bya damper connection such as the steel bolt elongation

Effect of the member buckling and yield elongation of thesteel bolt on the seismic response out of the plane is shown incomparison with the response of the wall structure subjected tothe horizontal earthquake motions e earthquake evaluationmethod is also proposed considering the dynamic collapsemechanism A validity of the proposed method is shown bymeans of the accuracy between the analysis and the estimation

2 Examples of Aluminum Truss Structures

Since earthquake resistance standards in Japan were im-proved buildings which were designed on the basis of oldseismic standards before 1981 need to be reinforced quicklyon the basis of the exiting new ones

e aluminum braces are useful for seismic retrofitting ofexisting buildings because they achieve good workability in theerection site and reduce the seismic loading and additional loadson the foundations due to their lightweight and aluminum alloymembers owing to their long-term corrosion resistance

3 Connection Design of an AluminumTruss Wall

We propose two types of connection systems an aluminumball-jointed truss wall and aluminum pin-connected bracesAs described in more detail below both systems have im-proved in their plastic deformability to resist excessive seismicloads In our previous paper [1] the brittle collapse mecha-nism of the truss wall structure to resist lateral loads has beeninvestigated to evaluate the earthquake resistance capacity

Figure 2 illustrates the aluminum alloy ball-jointed trussconnection used to retrofit this nodal connection consists ofaluminum parts and a steel bolt All aluminum parts areextruded and in heat-treated aluminum alloy 6061-T6 theend plug is welded at its edge to the strut by using a frictionwelding method Friction welding which is one of thevarious welding processes is known for high joint efficiencyand high reliability in comparison withMIG or TIGweldinge collar transfers the compression stress and the steel bolt

transfers the tension stresse bolt is made of high-strengthsteel the figure of the bolt is slimmed in the axle of the bolt asshown in Figure 2

e connection of the truss wall is designed by means ofthe condition such as Ncr gt BNu where Ncr is a memberbuckling or an ultimate strength of the welded joint and BNuis an ultimate strength of the bolt e bolts are able to extendby excessive tensile loading in a major earthquake thereforethe truss wall structure achieves a good hysteretic curve asdescribed in Figure 3 In our previous paper [2] it is in-vestigated that the fuse-type connection realizes the tensionyield of the steel bolt before the member buckling occurs

e fuse connection consists of two hubs two collars twobolts and a strut as shown in Figure 4 e steel bolt resistsagainst the tension axial stress and the collar resists againstthe compression axial stress as far as the resistancemechanism of the axial stress between the hub and strut isconcerned Figures 5ndash7 show the numerical analysis modelin this study

6 Time-History Analysis of the Truss Wall

Geometric and material nonlinearity is considered in thetime-history analysis of the truss walls subjected to thehorizontal earthquake motion of El Centro NS (PGA561 msec2) e Rayleigh damping matrix is used inthis analysis e damping factor h 002 is used for firstand second vibration modes in the damping matrixe numerical integration method uses the Newmarkmethod β14 is used in this study because β 14will be unconditionally stable for the seismic responseanalysis

61 Analysis Model of the Double-Layer Partial CylindricalTruss Wall e truss wall has a configuration as shownin Figure 10 e length is 14m with 7 grids and theheight is 72 m with 4 grids e bottom nodes are con-strained for all directions e top nodes are free for thehorizontal plane (X direction) ey are restrained for thevertical direction (Y direction) and out of the plane (Zdirection)

An aluminum alloy A6061-T6 is used in the strut anda high tensile strength steel SCM435 with the yieldstrength of 649 Nmm2 is used in the connection steel boltA truss model is used in the analysis e model isa lightweight structure made of an aluminum alloy estructure can bear the dead load which is confirmed as thestatic design

Table 1 shows the member length L (mm) the slen-derness ratio λ the cross-sectional secondary radius i (mm)and the sectional area A (mm2) e member is determinedby the earthquake-proof design using the base shear co-efficient of 10 And the strength of pullout of the bolt such asthe yield axial force is also shown in Table 1

the two walls with the 1m and 04mwall depths are obtainedby means of the eigenvalue analysis respectively e firstand third natural periods T1 and T3 are shown in Figure 11e corresponding vibration modes are also shown inFigure 11 respectively It is seen that the shear deformationmode of a wall appears in the first vibration mode of the twowalls and the third mode of the wall with the 1m depth eout-of-plane shape in the third mode of the wall with the04m depth also appears due to the lower bending rigiditythan in the wall with the 1m depth e study focuses on theout-of-plane deformation of the thin depth wall subjected toearthquake motions

63 Dynamic Response Behavior of the Truss Walls SubjectedtoEarthquakeMotions In the present study the earthquakeresistance capacity of the dome is evaluated by in-vestigating the maximum horizontal displacement δmax atthe top of the wall subjected to horizontal earthquakemotions with the peak ground acceleration (PGA) multi-plied by the PGA amplification factor λE e damage limitartificial earthquake motion with a phase characteristic ofthe El Centro NS wave is used in the seismic responseanalysis e PGA is taken to be 112msec2 e re-lationship between λE and δmax of the two walls withdifferent wall depths is shown in Figures 12 and 13 e

location of the steel bolt yield is shown in Figure 14 at thebeginning of the bolt yield and the member bucklingrespectively It is seen in the results that the bolt yieldprecedes the member buckling and the linear relationshipbetween λE and δmax is kept within the plastic region fromthe beginning of the bolt yield to the beginning of themember bucklingis means that the response control canbe feasible by means of the fuse-type connection such as thesteel bolt yielding elongation

e time-history energy response of the restoring forceof the member and the damping of the structure to thein-plane (X) and out-of-plane (Z) directions is shown inFigures 15 and 16 respectively It is seen in the wall withdepths that the structural damping almost absorbs the inputenergy due to the seismic response just before the memberbuckling occursemember buckling induces the absorbedenergy in the case of the wall with 1m depth subjected toearthquake motions with λE 94 e out-of-plane alsoconsumes energy greater due to member buckling as seen inTable 2 On the contrary a sudden dynamic collapse of thewall with the 04m depth occurs just after the memberbuckling because of the bending rigidity out of the planewith the less wall depth

e maximum strains of the steel connection bolt inboth depths are 2 times less than the first yield strain asshown in Figure 17 It is confirmed in the study that allmembers in both walls are also 2 times less than the firstyield strain

7 Evaluation Method of the ResponseEstimation by means of theLimit Displacement

e comparison between the PGA amplification factor λEof the input earthquake motion and the maximum dis-placement δmax to the horizontal in-plane (X) direction atthe top of the wall with the 1m and 04m wall depths isshown in Figure 18 by means of the dynamic analysis Andthe proposed estimation method uses the limit displace-ment e limit displacement δud is defined in the study as12δy1 in the red line in Figure 18 e structural yielddisplacement δy1 is the horizontal in-plane displacement δat the top of the wall just on the first occurrence of the steelbolt yield It is also noticed that a ductility factor of thesteel bolt is taken to be within 20 at the limit displacementδud is is the reason that the limit displacement δud istaken to be 12δy1 e structural buckling displacement

δy2 is the horizontal in-plane displacement δ at the top ofthe wall just on the first occurrence of the strut memberbuckling

e evaluation method of the response estimation bymeans of the limit displacement is the first to calculate theδmax using the linear relationship between λE and δmax It canbe evaluated for engineers that the dynamic collapse occursin the case of δmax larger than δud e estimation value λEUis practically calculated by the proposed method using the

response analysis e proposed method can be applied tothe wall with an aspect ratio of the shear-dominant de-formation type

3 Connection Design of an AluminumTruss Wall

We propose two types of connection systems an aluminumball-jointed truss wall and aluminum pin-connected bracesAs described in more detail below both systems have im-proved in their plastic deformability to resist excessive seismicloads In our previous paper [1] the brittle collapse mecha-nism of the truss wall structure to resist lateral loads has beeninvestigated to evaluate the earthquake resistance capacity

Figure 2 illustrates the aluminum alloy ball-jointed trussconnection used to retrofit this nodal connection consists ofaluminum parts and a steel bolt All aluminum parts areextruded and in heat-treated aluminum alloy 6061-T6 theend plug is welded at its edge to the strut by using a frictionwelding method Friction welding which is one of thevarious welding processes is known for high joint efficiencyand high reliability in comparison withMIG or TIGweldinge collar transfers the compression stress and the steel bolt

transfers the tension stresse bolt is made of high-strengthsteel the figure of the bolt is slimmed in the axle of the bolt asshown in Figure 2

e connection of the truss wall is designed by means ofthe condition such as Ncr gt BNu where Ncr is a memberbuckling or an ultimate strength of the welded joint and BNuis an ultimate strength of the bolt e bolts are able to extendby excessive tensile loading in a major earthquake thereforethe truss wall structure achieves a good hysteretic curve asdescribed in Figure 3 In our previous paper [2] it is in-vestigated that the fuse-type connection realizes the tensionyield of the steel bolt before the member buckling occurs

6 Time-History Analysis of the Truss Wall

Geometric and material nonlinearity is considered in thetime-history analysis of the truss walls subjected to thehorizontal earthquake motion of El Centro NS (PGA561 msec2) e Rayleigh damping matrix is used inthis analysis e damping factor h 002 is used for firstand second vibration modes in the damping matrixe numerical integration method uses the Newmarkmethod β14 is used in this study because β 14will be unconditionally stable for the seismic responseanalysis

61 Analysis Model of the Double-Layer Partial CylindricalTruss Wall e truss wall has a configuration as shownin Figure 10 e length is 14m with 7 grids and theheight is 72 m with 4 grids e bottom nodes are con-strained for all directions e top nodes are free for thehorizontal plane (X direction) ey are restrained for thevertical direction (Y direction) and out of the plane (Zdirection)

An aluminum alloy A6061-T6 is used in the strut anda high tensile strength steel SCM435 with the yieldstrength of 649 Nmm2 is used in the connection steel boltA truss model is used in the analysis e model isa lightweight structure made of an aluminum alloy estructure can bear the dead load which is confirmed as thestatic design

Table 1 shows the member length L (mm) the slen-derness ratio λ the cross-sectional secondary radius i (mm)and the sectional area A (mm2) e member is determinedby the earthquake-proof design using the base shear co-efficient of 10 And the strength of pullout of the bolt such asthe yield axial force is also shown in Table 1

the two walls with the 1m and 04mwall depths are obtainedby means of the eigenvalue analysis respectively e firstand third natural periods T1 and T3 are shown in Figure 11e corresponding vibration modes are also shown inFigure 11 respectively It is seen that the shear deformationmode of a wall appears in the first vibration mode of the twowalls and the third mode of the wall with the 1m depth eout-of-plane shape in the third mode of the wall with the04m depth also appears due to the lower bending rigiditythan in the wall with the 1m depth e study focuses on theout-of-plane deformation of the thin depth wall subjected toearthquake motions

63 Dynamic Response Behavior of the Truss Walls SubjectedtoEarthquakeMotions In the present study the earthquakeresistance capacity of the dome is evaluated by in-vestigating the maximum horizontal displacement δmax atthe top of the wall subjected to horizontal earthquakemotions with the peak ground acceleration (PGA) multi-plied by the PGA amplification factor λE e damage limitartificial earthquake motion with a phase characteristic ofthe El Centro NS wave is used in the seismic responseanalysis e PGA is taken to be 112msec2 e re-lationship between λE and δmax of the two walls withdifferent wall depths is shown in Figures 12 and 13 e

location of the steel bolt yield is shown in Figure 14 at thebeginning of the bolt yield and the member bucklingrespectively It is seen in the results that the bolt yieldprecedes the member buckling and the linear relationshipbetween λE and δmax is kept within the plastic region fromthe beginning of the bolt yield to the beginning of themember bucklingis means that the response control canbe feasible by means of the fuse-type connection such as thesteel bolt yielding elongation

e time-history energy response of the restoring forceof the member and the damping of the structure to thein-plane (X) and out-of-plane (Z) directions is shown inFigures 15 and 16 respectively It is seen in the wall withdepths that the structural damping almost absorbs the inputenergy due to the seismic response just before the memberbuckling occursemember buckling induces the absorbedenergy in the case of the wall with 1m depth subjected toearthquake motions with λE 94 e out-of-plane alsoconsumes energy greater due to member buckling as seen inTable 2 On the contrary a sudden dynamic collapse of thewall with the 04m depth occurs just after the memberbuckling because of the bending rigidity out of the planewith the less wall depth

e maximum strains of the steel connection bolt inboth depths are 2 times less than the first yield strain asshown in Figure 17 It is confirmed in the study that allmembers in both walls are also 2 times less than the firstyield strain

7 Evaluation Method of the ResponseEstimation by means of theLimit Displacement

e comparison between the PGA amplification factor λEof the input earthquake motion and the maximum dis-placement δmax to the horizontal in-plane (X) direction atthe top of the wall with the 1m and 04m wall depths isshown in Figure 18 by means of the dynamic analysis Andthe proposed estimation method uses the limit displace-ment e limit displacement δud is defined in the study as12δy1 in the red line in Figure 18 e structural yielddisplacement δy1 is the horizontal in-plane displacement δat the top of the wall just on the first occurrence of the steelbolt yield It is also noticed that a ductility factor of thesteel bolt is taken to be within 20 at the limit displacementδud is is the reason that the limit displacement δud istaken to be 12δy1 e structural buckling displacement

δy2 is the horizontal in-plane displacement δ at the top ofthe wall just on the first occurrence of the strut memberbuckling

e evaluation method of the response estimation bymeans of the limit displacement is the first to calculate theδmax using the linear relationship between λE and δmax It canbe evaluated for engineers that the dynamic collapse occursin the case of δmax larger than δud e estimation value λEUis practically calculated by the proposed method using the

response analysis e proposed method can be applied tothe wall with an aspect ratio of the shear-dominant de-formation type

δy2 is the horizontal in-plane displacement δ at the top ofthe wall just on the first occurrence of the strut memberbuckling

e evaluation method of the response estimation bymeans of the limit displacement is the first to calculate theδmax using the linear relationship between λE and δmax It canbe evaluated for engineers that the dynamic collapse occursin the case of δmax larger than δud e estimation value λEUis practically calculated by the proposed method using the

response analysis e proposed method can be applied tothe wall with an aspect ratio of the shear-dominant de-formation type

8 Conclusions

is study deals with the partial cylindrical truss wall withthe damper joint connection due to horizontal earthquakemotions It is confirmed in the dynamic elastoplastic analysis
