EXPERIMENTAL STUDY ON SHEAR STRENGTH OF THE CONNECTION BETWEEN OUTER BUCKLING-RESTRAINED BRACES AND RC BUILDINGS FOR SEISMIC RETROFIT

Abstract

Buckling-restrained braces are used to a seismic retrofit of RC buildings. A connection between outer buckling-restrained braces and RC buildings is important for the seismic retrofit to be reliable. It is required for the connection to minimize shear displacements. The connection receives cyclic loads while the buckling-restrained brace absorbs seismic energy. Due to the suffering cyclic loads, an unexpected deterioration on the connection would proceed. The authors conducted cyclic loading tests of the connection. Basic information for the designing has been provided.
