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 the X direction. It is not ideal to have torsional as mode 2". 1. What is the effect of Mode-2 on design as we usually concerned with fundamental frequency.? 2. How torsional modifier in ETABS is going to affect in this case? Any addition would be highly appreciated. Thanks in Advance.
