摘要
通过对两组8根钢筋混凝土框架柱的试验和分析,主要研究了斜向水平荷载作用下两个主轴方向上配箍量不等的柱的破坏形态和受剪性能,其中第一组采用单调加载,第二组采用低周反复加载。试验结果表明,两个主轴方向上配箍量不等的柱在斜向水平荷载作用下的破坏形态与配箍量相等的情况相似,柱受压侧的两个角边容易发生钢筋与混凝土的粘结破坏。理论分析表明,其受剪承载力满足偏上限的类椭圆方程。有限元计算结果与试验值吻合较好。
The shear behavior of rectangle RC columns with different quantity of stirrups in both principal directions were investigated based on the experiment and analysis of 2 groups of 8 specimens, in which the first group is under cyclic loading and the second group is under the monotonic load. The test results show that the failure pattems of different quantity of stirrups in both principal directions are the similar to the same area of stirrups. A three-dimensional nonlinear finite element model for test specimens were applied to the analysis of RC frame columns, and the calculated values agree well with the experimental results.
