The buckling-restrained energy dissipation brace of type, including outer sleeve and core plate are taken, the interlude of the core plate is the first power consumption section, outermost two
Section is two linkage sections, is respectively the second power consumption section and the 3rd power consumption section, the first consumption between the first power consumption section and two linkage sections
The longitudinal section area of energy section is less than the longitudinal section area of the second power consumption section, and the longitudinal section product of the second power consumption section is less than the 3rd power consumption section
Longitudinal section area；The first positive stop lug boss is correspondingly arranged between the first power consumption section and the second power consumption section on core plate side, the
The second positive stop lug boss is correspondingly arranged between the one power consumption power consumption sections of Duan Yu tri-；First positive stop lug boss stretches into the first matched limit
Between position block and the second positive stop, and with leaving gap between the two, the second positive stop lug boss is respectively protruding into matched
Between first positive stop and the 3rd positive stop, and with leaving gap between the two, it is defeated by multistage power consumption dissipation earthquake
The energy entered, and reach and good energy consumption effect is attained by under a variety of earthquake magnitudes.The utility model passes through provided with multiple power consumption sections
Strengthen the anti seismic efficiency of buckling restrained brace, but be also additionally arranged multiple positive stop lug boss simultaneously, improve cost of manufacture.
Therefore it is badly in need of a kind of with low cost, buckling-restrained branch of segmented with favorable elasticity rigidity and multiple yield points
Support.
