| 摘 要： | 采用数值积分法编制了L形截面柱正截面承载力非线性分析程序,并进行程序验证。对三种肢长比的不等肢L形截面柱的三种优化配筋的Mx-My进行分析,得出不等肢L形截面柱合理配筋。结果表明,不等肢L形截面柱合理配筋形式应在肢端和折角处配置相同直径受力钢筋,在内折角处配置最小受力钢筋,其它位置按构造配筋,比较经济合理。在长肢端配筋率应大于短肢端配筋率。

| Abstract: | Based on the method of the numerical integral,a program for capacity of L-shape column is designed,and validated.It is analyzed that M_x-M_y curves of inequiaxial L-shape column with different optimization forms of reinforcements.It is proposed stressed steel bar should be at end and corner;the constructional reinforcement at other locations.Increasing reinforcement is helpful to improve engineering axial direction forces. |
