I have modelled an 8' Dia. x 63' High precast concrete coal stacking tube using elements in Staadpro v8i. The wall thickness is 9.5". The model has loads which include selfweight, conveyor belt tensions, wind loads, asymmetrical coal pressure, head house dead & live load, and seismic loads. The vertical moments in the tube are small compared to the moments in the foundation. The moments in the tube at 2.5' above top of foundation also drop off to give "Only minimum steel required" for the reinforcing steel in longitudinal and transverse direction. Is this what happens for a cylindrical tube versus a cantilever beam?
