Silos are commonly used for bulk storage of grain, coal, cement, carbon black, food products etc. Here in this project evaluates the effect of local slenderness on silo supporting steel structure. The strength of compression members made of steel sections depends on their slenderness ratio. Higher strengths can be obtained by reducing the slenderness ratio. Local buckling has the effect of reducing the load carrying capacity of columns and beams. Therefore, it is desirable to avoid local

... g before yielding of the member. For finding out the local slenderness, a silo supporting steel structure is modelled, analysed and designed using ETABS. Wind loads and earthquake loads as per Indian Standard codes are applied on the structure in order to find out the effect of lateral loads on slenderness limit. Modal analysis is done to get the required number of mode shapes. Response spectrum analysis is done to determine the dynamic characteristics of the structure.
