本文介绍无粘结部分预应力板柱节点在反复荷载作用下的滞回特性、延性、强度和破坏形态。试验结果表明,在反复荷载作用下,板中无粘结预应力筋的应力增量较小;非预应力普通钢筋暗梁有效地提高了板柱节点在极限状态时,传递不平衡弯矩的能力及确保板冲切区的完整性。采用不同无粘结预应力筋布置方式的两个节点均具有较好的滞回特性和延性,节点抗震性能良好。 This paper describes the hysteresis characteristics, ductility, strength and failure modes of unbonded partially prestressed plate-column joints under cyclic loading. The test results show that under repeated loading, the stress increment of unbonded prestressed tendons in the plate is small; non-prestressed normal steel dark beams effectively improve the transmission of unbalanced bending moment when the plate-column node is in the limit state. Ability to ensure the integrity of the board blanking area. The two nodes with different unbonded tendons have better hysteretic properties and ductility, and the joints have good seismic performance.
