Silo loading on Structural Analysis Software
Silo loading on Structural Analysis Software
(OP)
Hello. I'm currently studying granular material silo analysis and design. Up to now, I know how to calculate the horizontal and vertical pressures the stored material exerts on the silo walls via Janssen's Method. I want to analyse the silo with a structural analysis software like SAP2000 or RSAP, but it is not yet clear to me how should I load the finite elements.
For horizontal pressure, it is similar to hydrostatic pressure on the walls. But for vertical pressure, I'm not sure how to apply the pressures on the finite elements. One way I thought it could be done is by applying a linearly distributed load on the perimeter of the sections that make up the silo, but I'm not sure if it is theorethically correct.
Can someone help me to clarify my doubts?

You might want to consider wind load acting on the silo wall as part of the design if it is located outdoor. The wind load can be unevenly distributed on the silo parameter. Wall pressure applied as a function of polar angle is useful when considering wind action.
Hope my sharing useful.
