I am attaching the modal participation of mass of building
first mode and second mode time period is quite apart that is good but first mode seems to be torsional
help me out if ETabs modal results are placed as first torsion then followed by x and y .
I want to interpret the results if these are good that I can lock my structure and go into designing?
Moreover these are my center of mass and rigidity they are also 7 to 8% apart so I want to know if my building first mode is torsion.?
Thanks
