Three-level yield buckling-restrained energy dissipation supporting piece
The invention discloses a three-level yield buckling-restrained energy dissipation supporting piece which comprises an energy dissipation inner core and an outer restraining piece, and the energy dissipation inner core is installed in the outer restraining piece. The energy consumption inner core is provided with connecting sections located at the two ends of the energy consumption inner core, a second-stage yield section located in the middle of the energy consumption inner core and a first-stage yield section connected between the connecting sections and the second-stage yield section, and the second-stage yield section and the first-stage yield section are each provided with a weakening area. The weakening proportion of the cross section of the weakening area of the second-stage yield section is smaller than that of the cross section of the weakening area of the first-stage yield section. According to the three-stage yielding buckling-restrained brace, three-stage sequential yielding can be achieved, the brace can adapt to earthquake effects of different levels, on the premise that fixed-point yielding is achieved, yield displacement can be reduced, meanwhile, the brace yields in three stages, the brace yields and consumes energy step by step along with increasing of the earthquake effects, and the brace is effectively protected.
本发明公开了一种三级屈服防屈曲耗能支撑件，包括耗能内芯和外约束件，所述耗能内芯安装在所述外约束件内，所述耗能内芯设有位于所述耗能内芯的两端的连接段、位于所述耗能内芯的中部的第二级屈服段和连接于所述连接段与所述第二级屈服段之间的第一级屈服段，所述第二级屈服段和所述第一级屈服段均设有削弱区，所述第二级屈服段的削弱区的横截面的削弱比例小于第一级屈服段的削弱区的横截面的削弱比例。本发明的三级屈服防屈曲支撑件能实现三阶段的依此屈服，能适应不同水平的地震作用，在实现定点屈服的前提下，能够在降低屈服位移的同时使支撑呈三阶段屈服，且随地震作用的增大而逐级屈服、耗能，有效地保护支撑物。
