Discussion on limit values of axial compression ratio of frame columns for high building

Combined with the standard,this paper analyzed the factors for the axial compression ratio form the cross-sections of columns,the strength of concrete,the hoop reinforcement,the stirrup ratio.We find that the limited values of axial compression ratio of the steel reinforced concrete columns,the concrete filled steel tubes columns and the columns of the frame-shear wall structure is unnecessary.Some suggestions on the limit values of the axial compression ratio of columns are given,which can be referred to for the design.
