Limit values of axial compression ratio for steelreinforced concrete columns;

In this paper, an investigation on axial compression ratio of columns with T, L-shaped cross-sections is carried out by numerical method.

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

Based on the balancing condition of internal forces in the case of balanced failure,the theoretical calculation formulas of limit values of axial compression ratio for core steel reinforced concrete(CSRC) columns are derived,and the main parameters which affect the limit values of axial compression ratio of CSRC columns are analysed.

Study of ultimate axial compression ratio for RC inequal-leg special-shaped columns;

In the calculation of ultimate axial compression ratio for irregularly-shaped columns,the grid method is usually applied to the cross-section integration.

The ultimate axial compression ratio for the specially shaped columns is computed by the numerical method.

Study of the limit value of axial compression ratio in designing structural systems with special-shaped column;
