摘　　要：探讨钢筋混凝土T形柱最不利荷载角及其影响因素.利用编制的钢筋混凝土异形柱截面全过程数值分析程序,通过对多种工况下钢筋混凝土异形柱正截面承载力的计算分析,结果表明异形柱最不利荷载角的影响因素主要是轴压比;截面尺寸对最不利荷载角有些影响;而混凝土强度、纵筋配筋面积对最不利荷载角的影响很弱.研究结果为钢筋混凝土异形柱的设计和异形柱的可靠性分析提供参考依据.The most dangerous loading angle and its effect parameters were researched.Utilizing the developed program analysis for full-path of reinforced concrete specially-shaped columns,the cross-section bearing capacity of reinforced concrete T-shaped columns under different load actions,and the most dangerous loading angle was found,and its main effect parameters were axial compression ratio;cross-section dimension had comparatively less effect and concrete strength and ratio of long reinforce ratio had least effect.The research will afford useful information for design and reliability analysis of reinforced concrete specially-shaped columns.
