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。
The analysis programs on section bearing capacity of piece with T-shaped section with nu- merical 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 significant, which can be calculated as piece subjected to bending.
