I used Etabs software to analyse a high-rise building. And I want to use templated UBC-codes inside to calculate the Seismic load. My question is: whether or not I have to control the seismic load by base shear load which is manual calculation? (just for more clarification: I can control this by input the scale factor into Eartquake definition in Etabs) I would highly appreciate your answer.
