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?

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?
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...
