connections for ismc150

DESIGN CHECK FOR CONNECTION PLATE FOR ISMC150: -

Check the forces on bracket from STAAD outputForces on brackets : -

= 13.50= 0.00

Bending moments ,for DL+LL at support = 0.000

Design of Vertical plate : -= 250= 300= 8

Number of vertical legs per brackets, n = 1Forces & moments on each Plate

Vertical shear forces, V1 = Vv/n = 13.5 / 1 = 13.500Comp/ Tension forces, F1 = Vh/n = 0 / 1 = 0.000

= 75Bending moment induced, M1 = [V1 x eh] = 13.5 x 0.075 = 1.01

= 8.44 = 1.02 x 10^6 / (8 x 300 ^2 / 6) < Permissibale bending stress of MS = 165Hence plate is safe in bending

= 5.625 = 13.5 x 10^3 / (8 x 300 ) < Permisibale shear stress of MS = 100Hence Plate is safe in shear

= 0.00 = 0 x 10^3 / (8 x 300 ) < Permissibale Compressive stress of MS = 150

Hence the plate is safe in compression / tension= 0.002

= 13.5 x 10^3 x 75^2 x (2 x 250 + (250- 75) / ( 6 x 2 x 10^6) (8x300^ < Span/325 = 0.923

Hence the bracket is safe in Deflection

CHECK FOR ANCHOR FASTNER (CRACKED) FOR PLATE CONNECTION:-

Vertical shear forces, Vv

Horizontal shear forces, Vh

Width ,B1

Depth ,D1

Thickness, t1

Eccentricity for horizontal load , eh

Maximum bending stress,σb= M1 / ZXX =[M1 / (t x d2/6)]

Maximum shear stress induced ,σs = [ V1 / (t1 x D1)

Maximum comp/tension stress induced ,σct = [ F1/( t1 x D1 )]

Maximum deflection (cantilever) = V1 x eh^2 x (2B1 + (B1-eh))/6Esteel x Ixx
