The governing combinations for bottom columns are DCON16, DCON15, DCON14, 13 and DCON11 which include gravity as well as both wind and seismic loading whereas the axial load is PU= 12678 kips, Mx= -5777 kip-in, My= 25862 kip-in. The fc'= 8000 psi normal weight concrete and fy= 60000 psi.I have changed column dimensions keeping in view the moments in x and y directions but still no accurate results. Please help Waseem Bhai.

AOA, I am working on a G+33 Story Building on ETABS and will manually check it but i have some problems regarding the model. Seismic and Wind Analysis is considered but some of the columns on lower stories are failing. I have increased the X-section of columns up to 48" X 48" on lower stories along with i have reduced the torsional constant for columns but no gain. I have attached my model. Please check my model and guide me. Dual System.zip
