Experimental Investigations of RC Frames Retrofitted by Steel Braced Frames Using a New Hybrid Connection

Article Preview

In this paper, a new connection technique for installing steel braced frame inside an existing RC frame is proposed. The proposed connection, which is called “Hybrid Connection”, consists of high-strength grout, steel plates and high-strength bolts. In the current investigation, two fundamental modes, namely, Type I and Type II are experimentally verified. In the fundamental mode of Type I, the steel braces buckle and stretch, and the RC frame and the steel frame exhibit flexural behavior. In the fundamental mode of Type II, direct-shear failure happens in the hybrid connection at the beam connection, and punching (direct-shear) failure occurs at the top of RC columns.
