Fundametal period calculated by computer, Tc

Fundametal period calculated by computer, Tc


Im tryna find this Tc to compare with my Ta calculated by formula. Im using ASCE 7-10-2016 on seismic design. Where do i get this Tc in STAAD.Pro?


RE: Fundametal period calculated by computer, Tc

I'm not sure what this "Tc" is either. Can you give a specific formula number from ASCE 7?

Speaking of that....are you using ASCE 7-10 or 7-16? I'm not aware of any code called "ASCE 7-10-2016".

RE: Fundametal period calculated by computer, Tc

I'm not sure about Tc either. Where in the code do they use that term?

In older versions of the code, there used to be a TB which was the period calculated by "method B" or a rational analysis. In a program like STAAD, this TB would be the fundamental period with the most mass participation in the direction of interest.

RE: Fundametal period calculated by computer, Tc

@WAROse hey sorry i meant ASCE 7-16, got mixed up sometimes

However, midsize to large contractors need the predictable, auditable processes that ERP delivers. Download Now
