• 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…
  • Factor in X & Z direction and Scale factor for SRSS

    Hello Bentley support, I am working on a steel structure (Portal Reclaimer) which need to be designed in accordance to BNBC (Bangladesh Code). Can you please suggest how to assign parameter for SRSS response spectrum. However it is very similar…
  • Response Spectrum as per AIJ

    Hi Guys, I just want to know if STAAD supports response spectrum as per AIJ? The only option I have is to use Custom Spectrum Table but the problem is its very had to find Hazard Maps for Japan. Thank you.
  • 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…

  • Como obtener periodo de vibración para cada dirección X, Y y Z

    Saludos a todos, en México se ha modificado el análisis por sismo, me piden realizar la comprobación del cortante basal en cada dirección ortogonal, mínimo en 2 direcciones (X y Z), así como la verificación del estado límite de servicio para sismos frecuentes…
  • RE: Seismic analysis

    The structure is very stiff in Vertical direction ( Y dir.) . Generally, we consider the effect of vertical motion of the structure if there are cantilever and vertical projections. Thus, we don’t need to consider the modes with Y direction mass participation…
  • RE: Design as per Response spectrum results.

    Take a look at any of the program help sections related to response spectrum analysis, for example, Section - 5.32.10.1.8 Response Spectrum Specification per IBC 2012, which says: Dominant mode method. All results will have the same sign as mode number…
  • RE: Response spectra

    That information should be sufficient to define the response spectrum per IBC 2012. Ram Structural System is another program Bentley offers, one that I happen to be most familiar with, but STAAD.pro is fine for your task. Here's our FAQ on response…
