预制装配式结构梁柱节点被动耗能减振技术研究现状及展望
State-of-the-art and Prospect of Prefabricated Beam-column Connection with Passive Energy Dissipation Technology
摘要
Abstract
Due to the poor seismic performance of prefabricated structures in high seismic regions,its popularization and application are limited.Precast concrete frame structure is a commonly used seismic system,and the beam-column connection is the crucial factor affecting its seismic performance.Pas-sive energy dissipation technology,as advanced structural vibration control technology,can signifi-cantly improve the seismic performance of prefabricated structures.The passive energy dissipated de-vice is placed outside or inside the beam-column joint,which not only forms a new integral part with the joint,but also realizes passive energy dissipation,thus forming a new type of dual-functional con-nection with load-bearing and energy-dissipation under seismic loading.The prefabricated beam-col-umn connections with frictional dampers or metallic dampers,and the energy dissipation hinges used in the beam-column connection are summarized.A prefabricated two stage energy-dissipated beam-col-umn connection combined rotational friction damper and flexural yielding metallic damper is put for-ward to form a high performance prefabricated structural seismic system,which has important refer-ence significance for improving the design requirements of prefabricated structures in China and popu-larizing the practical engineering application of prefabricated structures.The research direction and fu-ture development trends in this field are also given from the author's point of view based on our recent research work and achievements.关键词
