Question

FEA.std 
 
 Hello everyone, 
 
 I need help for the attached model. 
 
 I am doing the FEA on StaadPro and i created the model as attached. However, the problem is that i cannot see any stress distribution on the plate after analysis. Can somebody help me on solving the problem?

Walls are not connected correctly to the slab. More detais on this topic an be found here: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/20702/connectivity-issues

Modestas · Answer

You have used a very large value of Subgrade Modulus, so the stresses on the plate become very small. Try to use a more realistic value of Subgrade Modulus and the results should become more reasonable. 
 As a side note, whenever you use tension/compression only springs, you should combine primary load cases as Repeat Loads, not Load Combinations.
