In determining the frequency modes for a structural frame supporting vibrating equipment, in addition to the equipment mass do we also include operating material load in the analysis?
thanks in advance
I am designing a RAFT foundation for a RC vault. The raft measures 16m x 20m x 2m thick for the most part, the walls are 1m thick with the total design load(unfactored) 22MN. In checking punching shear, what are the parameters one should consider. Further is there a bending shear issue?
