| 摘 要： | 探讨了型钢混凝土柱发生不同界限破坏状态的条件 ,分析了界限破坏状态的定义不同对型钢混凝土柱轴压比限值的影响 ,指出在充分考虑型钢受弯的情况下 ,配工字形型钢混凝土柱的轴压比限值并不能比普通钢筋混凝土显著提高 ,建议在抗震设计中采用配钢管或十字形型钢的型钢混凝土柱 ,以提高柱的延性。

| Abstract: | The paper describes the conditions in which the different cases of balanced failure for steel reinforced columns may occur, and analyses the influences of different definitions about the case of balanced failure on the limit values of axial compression ratio for steel reinforced columns. It is pointed out that under the circumstances of making full use of the moment carrying capacity of steel, the limit values of axial compression ratio for steel reinforced concrete columns with I shaped steel cannot be remarkably raised compared with reinforced concrete columns. It is suggested the steel reinforced concrete with steel tube or cross shaped steel be adopted to improve the ductility of columns in seismic design. |
