【摘要】 采用全过程非线性的数值分析方法,计算了钢筋混凝土不等肢T形、L形和十字形柱截面模型在792种工况下的截面曲率延性比。在此基础上,分析了影响不等肢异形柱截面延性最不利荷载方向的因素,并得出了这3种截面不等肢异形柱在上述工况下的截面延性最不利荷载方向。更多还原

【Abstract】 Based on the method of the nonlinear analysis of complete response process,the curvature ductility ratio for RC arbitrary inequiaxial T-shaped,L-shaped and "十"shaped columns subjected to 792 load conditions is calculated.On the basis of calculation results,the factors influencing the worst load orientation are analyzed and load orientation of the least curvature ductility of three kinds of sections is presented.更多还原
