【摘要】 采用数值积分法编制了T形截面柱正截面承载力非线性分析程序,对5种不同配筋的等肢T形截面柱,在不同轴压比下的Mx—My曲线进行了计算,分析了不同荷载角的极限弯矩变化规律,探讨了截面配筋对截面承载能力的影响,得出了等肢T形截面柱的合理配筋。理论计算值与试验结果的比较表明,二者吻合较好。最后,对等肢T形截面柱的工程设计提出了建议。更多还原

【Abstract】 A nonlinear analysis program for capacity of T-shaped columns with numerical integral method is complied.Based on Mx—My curves of 5 optional reinforcement T-shaped columns with equal legs under different axial compression ratios,the maximum moments in various loading angles are analyzed.The effect of reinforcement arrangement on capacity is discussed.The rational reinforcement arrangement of T-shaped columns with equal legs is proposed.Comparison between the theoretical values and experimental results shows that they are in good agreement.Finally,some suggestions in practice design for T-shaped columns with equal legs are given.更多还原
