DAMAGE-CONTROLLED TRUSS BEAM USING BUCKLING RESTRAINED DEVICES AT LOWER MEMBER

Evaluation of Bending Moments at the Node above the Buckling Restrained Member

Abstract

This paper discusses damage controlled truss beam using buckling restrained members as a force limited member. In this paper, cyclic loading tests focusing on truss beam with or without buckling restrained member and detail of joint above the buckling restrained member was conducted in order to confirm structural behavior of the truss. The findings obtained from the tests are summarized as follows: (1) the deformation capacity of truss with the buckling restrained member is superior to that without the member; (2) In the truss with buckling restrained member, bending deformation was caused on the joint above the buckling restrained member.
