WEBINAR: Response Spectra Analysis using ETABS

[@yasar1abdurrahman348]

Csi should review and check these webinars for accuracy of information presented before posting them online.

What inputs do you add for the "Loads applied" for a Ritz analysis?

How to combine the response spectrum with gravitational loads? I have made some iterations placing the dynamic shear loads per floor manually to obtain a coherent stress diagram and not all positive or negative as the spectrum does. When comparing both scenarios (Dead+ RSX) / (Dead+EQx) (EQx lateral dynamic loads entered manually), I find that directly combining the spectrum with gravitational loads does not give similar and sometimes non-coherent values.

what about the mass source!!

how to use the excitation angle?

[@wansonsylvain857]

What if I didn’t define any modal cases but in the load pattern, I specified and define the seismic lateral with all their parameters (codes, PGA, spectrum type, etc) for X direction and Y direction and choose automatic combinations. Won’t the program perform the seismic analysis???

hi, why is scaling not done?

[@M.Khan325]

Thanks for the video.. Can u plz upload a video on the equipment loads on slab accounting the vibrations and its analysis???

How to check excitation angle of building

[@faisalzamankhan4657]

First find out base shear in both direction x and y then excitation angle = tan-1(Fy/Fx)

[@jigarrana2879]

Can etabs automatically do structural analysis and gives the quantity of materials?

[@junio5456]

nop

[@yiannifunataoldotcom]

Jigar rana yes of course

[@nizamieminov3648]

thank you.
