SEISMIC RESPONSE OF REINFORCED CONCRETE SILOS

Rajani S Togarsi

Abstract: Silos are the stack-like structures that are more commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. As the density, flow and friction properties of stored material vary, the loads applied on silo structure and associated load carrying system also vary. In this paper reinforced concrete silo supported with shear walls and supported on only columns are considered with same dimensions. These two silos are modeled using Finite Element Method package software SAP 2000.These are molded for the soil type II situated in the zone II when silo is empty, partially filled and fully filled with storage material. These models are analysed for load combination 1.5(DL+IL) according to IS 1893 (Part-I) : 2002 and then response of reinforced concrete silo with shear wall and without shear walls has been determined in terms of Lateral displacement. The results reveal the effect of stored material on non-linear seismic behavior of Reinforced Concrete Silo
