Structural Behaviour of RC Silo under Gravity and Infill Loads
Silo structures have been used for industrial as well as domestic storage purposes. The silos are often subjected to static and dynamic loading conditions such as gravity load, granular infill pressure, thermal load due to storage material, wind as well as earthquake loads. As the density, flow and frictional properties of grains, cement, coal, carbon black, etc. vary widely, failure stresses may vary in different parts of silo. In the present study, in addition to the gravity loads, the influence of lateral pressure was studied due to infill material at various occupancy levels, viz. 33%, 50%, 66% and 100%. The silo structure has been modelled in ABAQUS/CAE module and a numerical investigation has been carried out. The concrete structural components were modelled using solid brick elements (C3D8R), whereas, truss elements (T3D2) were used to model the internal reinforcement. The Concrete Damage Plasticity material model was used to simulate the material behaviour of the concrete. The results were obtained and discussed in terms of critical stresses and lateral deflection in the silo wall along the height, with different occupancy levels of infill material. At last appropriate solutions that improve the design of reinforced concrete silo have been suggested.
