• Response Spectrum Analysis & Design Forces Problem for Shear Wall Design in RCDC

    Hi everyone, I have faced a problem importing analysis forces from Staad Pro to RCDC for a shear wall example. I have performed seismic analysis by using the response spectrum method for a box-shaped and cantilever shear wall in StaadPro. I can determine…
  • 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…
  • RAM Frame Dynamic Analysis Criteria

    When performing a dynamic analysis for Response Spectrum in Ram Frame, is it correct to check the reduced stiffness for steel members in the criteria? I have a situation where I need to scale up my dynamic loads to achieve the 0.85*ELF forces. The question…
  • RESPONSE SPECTRUM MODAL ANALYSIS

    Good morning, I'm trying to perform response spectrum modal analysis with Response spectrum user define data option on a multistory concrete building. The porpoise is to introduce in the FE model, seismic actions according to Italian design code (NTC2018…
  • RAM Frame - IS 1893:2016 Response Spectra Analysis Scale Factor

    Could someone please confirm that scaling the Response Sectra Analysis generated in RAM Frame using the Indian Standard IS 1893:2016 code does not include an adjustment for the Zone Factor, Z? If this is the case, I would assume the scale factor should…
