| 摘 要： | 为研究钢筋混凝土框架柱的抗震性能,进行了矩形截面不等肢配箍混凝土框架柱在斜向水平荷载作用下的抗剪强度试验研究,对框架柱在斜向水平荷载作用下的受剪承载力进行有限元分析,并与试验结果进行比较,研究了两向不等肢配箍矩形截面柱在静载和低周反复荷载作用下双向受剪承载力的相关关系,推导了双向受剪承载力计算公式。研究结果表明,斜向水平荷载作用下,不等肢配箍混凝土框架柱双向受剪承载力的相关关系近似符合椭圆规律,为不等肢配箍混凝土框架柱的受剪承载力设计提供参考。

| Abstract: | In order to research the seismic behavior of RC frame columns,the shear strength of rectangular section RC frame columns with different areas of stirrups in two directions under lateral bevel load was investigated by experiment and nonlinear finite element method.The results of nonlinear analysis were compared with those from experiment,and the correlation equation of bilateral shear strength of RC frame columns under static load and low-reversed cyclic load was analyzed.Then,a new design method was presented.It is shown that the influences of the lateral bevel load on the shear strength of rectangular section RC frame columns with different areas of stirrups in two directions accord with the ellipse law,which may be served as a reference for the design of shear strength of RC frame columns with different areas of stirrups in two directions. |
