摘要
带有可更换构件的结构体系是指,在结构中适当部位设置可更换构件,通过集中塑性变形耗散地震能量,保护结构其余部分不受破坏,地震后不影响结构的使用,更换构件后结构全部恢复正常功能。本文介绍了带有可更换构件结构体系的发展现状,总结了带有可更换构件的桥梁结构、框架结构、框架-支撑结构、剪力墙结构的研究进展,并探讨了今后的研究方向及重点领域。
Structural system with replaceable members is a type of structure, in which the replaceable members are installed to concentrate the plastic deformation and dissipate earthquake energy, while the rest of the structure re- mains intact. Through this method, the use of the structure will not be affected and the whole structure regains full capacity after replacement. This paper summarizes the recent researches on different kinds of replaceable members in bridge systems, frame systems, frame-brace systems and shear wall systems. Finally, the trends and futher re- searches are disscussed.
