Assalam o alaikum..
My building is in zone 4 with SMRF. Majority of its column are Over stressed in 6/5 Beam Column Capacity Ratios. Columns are pass in all other checks. Size of column is 18x18 and building has just two stories. Longitudinal Reinforcement is ranging from 1% to 1.5%. Shear reinforcement going upto Av/s =0.18........ I cant increase size of column because it is already 18x18. How can i solve this problem??
