Staad.PRO Seismic Response Spectrum (CQC)
Hi. I am working on a steel structure and i have some issues with the seismic loads.
That are the flexure MZ diagrams for the pure seismic load case in X direction (longitudinal).
It caught my attention the results for the beam element marked in…

RE: spectral analysis with dynamic response module
Hi aaa123,
I understand that your question is
Do you need to split SPLOAD command to be 3 commands for X Y and Z.
The answer is "NO NEED".
You can make it the same line. Directional spectrum will be combined by using SRSS method by SACS default…
Seismic Response Spectrum - Equivalent Static Load
Dear Sir,
I am curious about Equivalent Static Loads generated from Dynamic Response Module when we used ' Response Spectrum ' Approach.
Theoretically, for modal response, internal member force and moment for each mode will be combined by CQC or SRSS…
16. How is the Response Spectrum Analysis performed in AutoPIPE Vessel?
Answer.
A response spectrum analysis is run by using linear interpolation for the following site spectrum period and acceleration in the Earthquake tab under Vessel Properties>Load Conditions :
Seismic code used in ASCE 7-2010.
The analysis…
