ObjectivesTo study pre engineered building.To prepare a model of P.E.B.To analyze structure using Staad Pro.To design sections, connections etc.To study the effect of P.E.B. for following
issues:To reduce complexity on site.To achieve accuracy.Speed of work.

Pre Engineered BuildingSteel buildings in which excess steel is
avoided by Tapering the sections.Tapering is done as per Bending Moment
requirements.Components are manufactured in factory and
assembled on site.Larger plate dimensions are used in areas of
higher load effects.

Problem statementInternal dimensions of building: l=60 m, b=15
mHeight of building up to eaves level= 6 mLocation of building= Islampur (pune region)Type of roofing = G.I.sheetsArea of opening (permeability of building 5% to
20%)Angle of rafter = < 100
Spacing between two columns = 6 mNumber of frames = 10

Load calculationDead load:1. Wight of purlin :5 kg/m2
2. Weight of sheeting :5 kg/m2
Total weight :10 kg/m2=0.1kN/m2
3. Self weight of tapered section

Live loadLive load =0.75 kN/m2 (Angle lesthan 10
0) = 0.75*6
Live load =4.5 kN/m2
Collateral load:Collateral load = 0.2* 6 =1.2 KN/M

AdvantagesPEB System is zero maintenance & superior
in strength than conventional.Lower Cost.Quality Control.Large Clear Spans.strict quality control environment, thereby
ensuring superior quality & finish.Easier to incorporate future expansions

DisadvantagesNot used for multi-storey building.Technical person is required on site.Special Machinery is required.Design of member takes more time.

ConclusionUsing of PEB instead of CSB may be reducing
the steel quantity.Reduction in the steel quantity definitely
reducing the dead load.Reduction in the dead load reducing the size
of Foundation.Using of PEB increase the Aesthetic view of
structure.
