Research progress of structural systems with replaceable energy dissipation beams

可更换耗能梁作为一种新型的功能可恢复结构已经逐渐成为当前学者研究的热点。为了研究可更换耗能梁的发展前景,对剪力墙结构、框架结构、框架-支撑结构体系中的可更换耗能梁进行了论述,总结了国内外学者对于可更换耗能梁的设计方法。通过分析不同体系下可更换耗能梁的抗震性能,结果表明:可更换耗能梁设计简单、更换方便、传力明确。带可更换耗能梁的结构具有较好的抗震性能和可更换性能,耗能和损伤能够集中在可更换耗能梁部分,震后通过更换可更换耗能梁即可快速恢复结构的使用功能。可为今后功能可恢复结构的研究提供理论基础。

As a new type of functional recoverable structure,replaceable energy dissipation beam has gradually become a research hotspot of scholars. In order to study the development prospect of replaceable energy dissipation beams,the replaceable energy dissipation beams in shear wall structure,frame structure and frame support structure system are discussed,and the design methods of replaceable energy dissipation beams by scholars at home and abroad are summarized. By analyzing the seismic performance of replaceable energy dissipation beams under different systems,the results show that the replaceable energy dissipation beams have the advantages of simple design,convenient replacement and clear force transfer. The structure with replaceable energy dissipation beam has good seismic performance and replaceable performance. The energy consumption and damage can be concentrated in the replaceable energy dissipation beam. After the earthquake,the service function of the structure can be quickly restored by replacing the replaceable energy dissipation beam. It can provide a theoretical basis for the research of functional recoverable structure in the future.
