地震动的随机性使地震时地面的水平运动可以来自任一方向,因此房屋的钢筋混凝土柱有可能在随机地震动下斜向受力而发生破坏。提出了将柱纵向钢筋向截面角部集中的方法以改善RC柱在斜向地震作用下的抗震性能,并通过低周往复试验进行了验证。结果表明:截面角部集中配筋柱在斜向地震作用下的抗震性能得到大幅度的提高。 The randomness of ground motions can make the horizontal ground motion come from either direction during earthquake. Therefore, it is possible that the reinforced concrete columns of houses may be damaged by the oblique force under random earthquake. The method of concentrating the longitudinal reinforcement of the column to the corner of the section is proposed to improve the seismic performance of the RC column under the oblique earthquake and verified by the low-cycle reciprocating test. The results show that the seismic performance of reinforced columns with concentrated corners at corners has been greatly improved under the action of oblique earthquake.
