• 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…
  • 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…
  • Unrealistic Deformation on Rigid Diaphragm in Ram SS

    Hi, I am currently modelling a 4 story concrete building with a single core with two levels of basement. I am trying to run the spectral analysis using AS1170.4 and I have set all my floor diaphragms to rigid diaphragm. The model dissipation for each…
  • RAM Frame Response Spectrum Base Shears

    I have a 2-story building modeled in RAM SS (v14.07), and I'm using Response Spectrum analysis in RAM Frame. The model contains a ground level framed floor, a raised 2nd floor, and a roof. The base is at the ground level framed floor (not the base). I…
  • RAM SS response spectrum S.F. & frame shear force difference.

    Hi, I have two questions. 1) RAM SS has response spectra input window and I need to input X and Y Scale factor(default =1.0). Should I input I(importance f)/R there as starting point? or I/R is already reflected? In other words, 1.0 is ok to…
