| Research Abstract |
The purpose of this research is to propose a new seismic retrofit technique for low to mid-rise RC buildings based on the fundamental ideas of lateral confinement. This idea is applied to columns before/after damage, shear walls, column-beam connections, steel braced frames and bond strength of reinforcement. As a result, great improvement in seismic performance is clarified experimentally. Next, buckling strength of steel braced frame on hybrid connection is proposed through analysis and calculation in this research.
