Abstract

This paper presents a deformable connection that is used to connect each floor system of the flexible gravity load resisting system (GLRS) with the stiff lateral force resisting system (LFRS) of an earthquake-resistant building. The deformable connection limits the forces transferred from the GLRS to the LFRS, and reduces the floor accelerations and force responses of the structure. The deformable connection consists of a buckling restrained brace (BRB) or a friction device (FD) which acts as a limited-strength hysteretic component, in parallel with low damping laminated rubber bearings (RB) which provide out-of-plane stability to the LFRS, post-elastic in-plane stiffness, and help with partial re-centering. Preliminary numerical simulations of a twelve-story reinforced concrete wall building structure with deformable connections showed reduced structural responses compared to a building with rigid-elastic connections.
