I am Using ASCE 7-16. See the attached Seismic loading screen shot. Eq. 12.8-3 and Eq. 12.8-4 doesn't Control. THE PROGRAM IS USING A PERIOD OF 0.306 SEC. IN ONE DIRECTION AND 0.692 SEC IN THE OPPOSITE DIRECTION. BUT THE PERIOD SHOULD BE THE SAME FOR BOTH DIRECTION. IT SHOULD BE CALCULATED FROM...
Hi Guys,
How Could you match Base shear in each direction in ETABS for equivalent lateral force system? here is a screen shot of etabs model. my base shear is different in each direction. I am only using one Lateral force system and that is concrete shear wall with R=5. the Base Shear should be...
Hi Guys,
How could I design the concrete shear wall for seismic lateral load combination with Rho=1.3 and vertical seismic load transferred to these concrete shear walls from above podium slab with omega at the same time in Etabs?
Hi Guys,
I got the following Warning when I run the response spectrum analysis with Ritz modal case in etabs. any recommendation on how to remove the warning?
* * * W A R N I N G * * *
ZERO RITZ STARTING VECTORS ELIMINATED,
NUMBER OF STARTING VECTORS REDUCED TO = 2
Hi Guys,
when I run the ETABS model I get the following error message:
OFFSET PLANE IS TOO DISTORTED FOR SHELL 1317.
Can someone tell me how I can locate the error and how to correct it?
No I am not a student. It posted here mistakenly since I am new here and I don't know why removed my post from structural engineering general discussion?
if we have a steel cantilever column and wood sheathed shear wall at the same line/Grid line as combination of lateral resisting system. what R(Response Modification factor) value to be used? the least R value for both lateral resisting system?
the cantilever column is added for strength in...
