Analysis of a Steel Truss Framed Structure Considering Lateral Load using STAAD.PRO Software

Steel structures are generally use in places where long span spacing is required with stability and within time limit. These structures are stable and rigid with easy and early fixation at site. These structures are open structures where wind effect is nominal, rigidity of such structures are comparatively more than RCC structures. These structures are easy to fix and dismantle. These are casted along with bolt or rivet connection which minimizes moment. The Truss Structure consists of members/elements that takes only tension or compression and no bending moment in what so ever form. In the engineering term the Truss is defined as the two-force member, where the members are so assembled that the assemblage works as a single unit. The truss structure is generally provided when we need a large open space. In this study we are presenting linear analysis of three different type of truss arrangement i.e. Flink, Howe and King post for long span open area of dimension35m x 25m. In this study we will also discuss the variations occur due to different type of sections such as ISMB, Channel section and Angle section. For analysis purpose we will use Staad.pro.
