| 摘 要： | 采用数值积分法编制了对T形截面构件的正截面承载力分析程序,通过对同一种截面配筋形式的等肢T形截面构件,在不同轴压比下的Mx-My曲线进行了计算、分析,提出以下建议:对抗震等级为3级的异形柱框架结构,在轴压比小于0.03时,轴压比对T形截面构件正截面承载力的影响不大,可以按受弯构件计算。 |
| 关 键 词： | T形截面构件 轴压比 数值积分法 Mx-My曲线 |

| Abstract: | The analysis programs on section bearing capacity of piece with T-shaped section with numerical integral method are developed.Based on the calculation results on Mx-My curves of same reinforcement piece with T-shaped section with equal legs under different axial compression ratio,it is concluded that: for a level-3 quake resistance frame structure when axial compression ratio is smaller than 0.03,the influence of axial compression ratio to the bearing capacity of piece with T-shaped section is not significa... |
| Keywords: | piece with T-shaped section axial compression ratio numerical integral method Mx-My curves |
