摘要
结合国内首个预制全装配式公建项目,选取典型框架处3种具有代表性的关键空间节点进行节点抗震性能分析。结合有限元方法,进行节点整体拟静力滞回性能研究,并与现浇框架节点、其他装配式节点进行比较。计算结果表明,所采用的预制型钢-混凝土组合节点,其承载力和节点延性均满足抗震设防要求,结构安全可靠。
Three kinds of typical space joints were selected from the first total prefabricated public building in China,and their seismic behavior was analyzed.The pseudo-static hysteretic behavior of these joints were studied by finite element analysis,and compared with joints in cast-in-situ frames and other prefabricated joints.The results show that the bearing capacity and ductility of the total prefabricated steel and concrete joints can satisfy the requirement for earthquake resistance and ensure the structural safety.The study results can provide design guidance for other similar projects.
