| Abstract: | Uniform design method is used to design the test plan. Tests of columns with different steel ratio and slenderness ratio under bias compression are carried out. The advantage of the uniform design is pointed out. The experience formula to calculate the ultimate bearing capacity is obtained. The relation formular of neutral axle and deflection changing with steel ratio and slenderness ratio in ultimate state are put forward. |
