预应力板墙结构的抗震性能

Test Investigation on Aseismic Behaviour of the Slab and Wall Structure with Prestressing in the Slab

根据实际工程背景,本文对无粘结预应力板墙结构的一个节点模型进行了试验研究。通过节点模型的设计和试验,着重讨论了无粘结预应力板墙结构的设计计算方法,对节点模型在反复水平荷载作用下的破坏形态、位移、延性和强度进行了较深入的研究,并讨论了预应力对剪力墙、楼板破坏性能的影响。

Based on the requirement of engineering practice, this paper investigates the aseismic behaviour of the slab and wall structure with the unbonded post-tensioned prestressing in the slab, such as the pattern of collapse, ductility, etc. , by designing and testing one half-scale slab and wall subassemblages. The effect of the post-tensioned prestressing on the failure behaviour of shear wall and slab is investigated further. This paper also discusses the design methods for the slab and wall components in such structures.
