针对火电厂型钢混凝土混合结构主厂房中典型异型节点的实际受力情况,完成了5个1/5缩尺比例的型钢混凝土异型节点低周反复加载试验,主要分析了沿柱高布置短肢剪力墙对型钢混凝土异型节点抗震性能的影响。研究结果表明:短肢剪力墙对型钢混凝土异型节点的裂缝开展具有较好的约束作用,设置短肢剪力墙后,型钢混凝土异型节点的滞回性能、耗能能力、承载能力、刚度特性与延性性能均有了较大的提高与改善,且配置横向短肢剪力墙的效果优于布置纵向短肢剪力墙。
According to the actual stress of the typical shaped joints in the main steel-framed hybrid concrete structure of thermal power station, five 1/5-scale low profile repeated loading tests were carried out, which mainly analyzed the short- Influence of force wall on the seismic behavior of profiled joints of steel reinforced concrete. The results show that the short-limbed shear wall has a good restraining effect on the crack initiation of profiled joints of SRC. After setting the short-limbed shear wall, the hysteretic behavior, energy dissipation capacity, load carrying capacity and stiffness characteristics of SRC shaped joints And ductility have been greatly improved and improved, and the deployment of horizontal short-limbed shear wall effect is better than the arrangement of longitudinal short-limbed shear wall.
