Abstract
A new energy dissipation device that combined the BRB and pipe damper systems to form the buckling restrained slit pipe dampers (BRSPD) is proposed. This device incorporates a slit pipe damper that is limited by the inner tube. The outer tube was used as a restraining mechanism. Slit in the pipe is used to control energy dissipation and deformation capacity. This damper is designed to provide adequate hysteretic performance through core yielding under both tension and compression. A series of cyclic loading tests were conducted on the BRSPD and component test with the proposed devices. It was found that the BRSPD sustained significant strength and energy dissipation capability before reaching 3% drift ratio, if adequate number of slits in the core pipe was used.
