Hello,
I am having some problems with a simple structure, it is a shelter anchored laterally on a concrete structure (these are the lateral supports) and on the ground. When I run the model, the support reactions at the floor level due to earthquake in direction Z is zero. This makes impossible to comply with the seismic requirement of the 80% of the base shear calculated using the ESM...
I would be grateful if someone could help me with this. Attached is the staad input
Thanks,
Regards,
