摘　　要：文章从试验研究和现场实践两个方面,阐述无凹槽壁的预制预应力叠合梁柱节点的应用情况。在试验研究方面,通过对3个试件的低周反复试验,研究试件的破坏形态、耗能、延性和强度指标,并提出试验结论;在现场实践方面,通过具体工程案例,阐述无凹槽壁的预制预应力叠合梁柱节点在节点优化设计、钢筋连接、模板安装等方面的实施情况。通过两方面内容阐述无凹槽壁的预制预应力叠合梁柱节点的可行性.This paper elaborates on the application of precast prestressed composite beam-column joints without groove walls from two aspects:experimental research and on-site practice.In terms of experimental research,the failure mode,ductility,energy consumption,and strength of three specimens are studied through low-cycle repeated tests,and experimental conclusions are proposed.In terms of on-site practice,specific engineering cases are used to illustrate the implementation of prefabricated prestressed composite beam-column joints without groove walls in terms of node optimization design,steel bar connection,and template installation.Elaborate on the feasibility of precast prestressed composite beam-column joints without groove walls through two aspects.
