Numerical Analysis for the Effectiveness of Buildings Seismic Resistance Capacity by Cable Reinforcement System

Abstract

Many old buildings have the problem of weak seismic horizontal load capacity Traditional building retrofit method may take time and must change original structure system. In this paper we developed a steel cable retrofit system which could add external cable system out of original building so the cable will add additional tension force when building take lateral earthquake force. We applied a numerical steel cable reinforcement system in low- and high-rise RC building to understand the different system performance in dynamic loading. From the numerical dynamic analysis of the SAP software shows that the additional steel cable reinforcement around the structure reduces the deformation and structural acceleration in the low- or high-rise building system. So we can applied the results to real building retrofit.
