摘要
本文介绍了两组预应力装配整体式板柱边节点,仅在纵向、仅在横向以及同时在两个方向施加预应力的情况下,承受反复荷载作用的试验情况。根据试验结果,对节点的承载能力、延性、恢复力特性及受力机理等方面进行了简要的分析,认为这种节点具有良好的抗震性能;其承载能力由纵向预应力钢筋、横向抗扭力矩及横向板缝非预应力钢筋三部分组成,理论计算值与实验结果相当接近。
This paper presents the tests of two prestressed slab-column joints under cyclicloads. The test results show that the loading capacity of this kind of joints consists of the longitudinal prestressing wries, mild reinforcements and transversal twist moments, Based on the tests, a calculating theory is presented, and compared with the test values, the vluaes of calculation are satisfactry.
