短肢剪力墙对型钢混凝土异型节学性能的影响研究

RESEARCH ON MECHANICAL PROPERTIES OF ABNORMAL SRC JOINTS WITH SHORT-LIMB SHEAR WALLS

  • 摘要: 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。

     

    Abstract: Following the actual stress states of typical abnormal joints of SRC hybrid structures in power plants, five 1/5 scale model abnormal joints were tested under low-cyclic reversed loading. The influence of setting short-limb shear walls along the height of SRC columns on the seismic performance of SRC abnormal joints was analyzed. The results show that short-limb shear walls can restrain the development of cracks, as well as greatly improve the hysteretic performance, energy dissipation capacity, bearing capacity, stiffness characteristics, and ductility performance of SRC abnormal joints; also, the improvement is greater in SRC abnormal joints with horizontal short limb-shear walls than in the joints with longitudinal short-limb shear walls.
