摘要:
为研究不同预应力下预压装配式节点的抗震性能,对三个预压装配式节点进行试验研究,得出节点在不同预应力下的滞回性能、承载能力、耗能能力、延性以及自复位性能.之后建立节点有限元模型,对节点进行扩大参数研究.结果表明:本文所提出的预压装配式节点拥有较好的自复位能力和耗能性能,在一定范围内,随着初始预应力的提高,节点的自复位能力越强,初始有效预应力的提高能在一定程度上提高节点的承载能力.但是初始预应力不是越大越好,初始预应力的提高会导致节点的耗能能力下降.
Abstract:
In order to study the seismic performance of preloaded prefabricated joints under different prestress, this paper makes an experimental study on three preloaded prefabricated joints, and obtains the hysteretic performance, bearing capacity, energy dissipation capacity, ductility and self resetting performance of the joints under different prestress. Then the finite element model of the joint is established and the expanded parameters of the joint are studied. The results show that the preloaded fabricated joint proposed in this paper has better self resetting capacity and energy dissipation performance. In a certain range, with the increase of initial prestress, the stronger the self resetting capacity of the joint is, and the increase of initial effective prestress can improve the bearing capacity of the joint to a certain extent. However, the greater the initial prestress is, the better. The increase of the initial prestress will lead to the decrease of the energy dissipation capacity of the joint.
