Hi guys, There is a question that I think lost of seismic designer often wonder about that is if there is torsion in first two modes, is that model always considered bad model? I found this in IS 1893:2016 that strictly states this (please see the picture below). “torsional mode of oscillati...

Salam, in buildings we check first three modes normally as far as i know, and we prefer first mode in x or y direction and third mode in torsion, if a building is symmetric with center core shear walls, what could be the reasons that it has first mode in torsion, even center walls has been rem...

Dear friends, I have building G+2P+7 floors, it's almost symmetric but the second mode is always torsion, I tried many sh. walls configurations but have the same result any tips Thanks I attached the model e2k, G+2p+7.e2k

Hi there, I am currently working on a 20+ story building (For educational purpose only) having dual resisting system (Moment resisting frames and concrete shear walls located in center). I intend to perform Non-Linear Static Pushover Analysis to capture non-linear response of the structure and...

Dear All, I received a peer review about the modal analysis I conducted in a high rise building. It states the following : "The preliminary mass participation factors indicate that mode 1 is predominantly translational in the transversal Y direction, mode 2 torsional and mode 3 translational in th...
