Abstract

This paper discusses experimental results on the seismic performance of RC frames retrofitted by additional steel braced frame using a hybrid connection and conventional connection. The ultimate strength and ductility of the hybrid connection are compared with the conventional connection, and test results of ten specimens retrofitted by two type connection were examined under cyclic loading tests. The main finding is that the proposed hybrid connection can satisfy the demand of high energy absorption for retrofitted RC frames under large seismic excitations. The hybrid connection obtains superior structural performance in viewpoint of strength and ductility in comparison with conventional connection.
