Structure Optimization Valuation for Steel Trusses Using STADD Pro Tool

The requirement of this study arises where sometimes it is difficult for taking too much time to choose an effective and economical truss shape or truss geometry during the design period. Now a day, our study about the steel structures, steel trusses make one of the major structural systems, which require for accurate and reasonable design. The shape and configuration mainly depend upon the span of trusses and a variety of loads. We have proposed to optimize the steel truss pattern for increase structural efficiency. Long span structures are needed to resist lateral forces over the span length without vertical members at the mid spans, for such structures truss arrangement is more beneficial to distribute tension and compression of each members. We have tested the considered models using Staad.Pro .The designed steel truss structures are analyzed for increasing structural efficiency. The present investigation will encourage the utilization of steel truss arrangement for long span structures which may be cost effective, easy and fast in assembling. and concluded that in truss arrangement howe type truss is comparatively best suitable whereas in terms of sections beam section is more resistible and economical.
