Abstract

As a senior capstone project, students worked on the vulnerability assessment and seismic retrofit of a six-story non-ductile reinforced concrete dual system building comprised of perimeter non-ductile reinforced concrete moment frames and non-ductile core shear walls. Students were given the as-built plans and specification of an existing building in Southern California that is considered to be at risk, from an earthquake resistant standpoint. Students performed structural analysis for both gravity and lateral systems using the SAP 2000 program for the as-built condition. Students then evaluated the demand-capacity ratios for each system. From this study, students were able to identify the main structural deficiencies which are concentrated around the exterior frames. The columns of the frames found lacking the required strength to meet the minimum accepted performance during a major earthquake. Students proposed a retrofit scheme to mitigate the risk of collapse due to seismic loading. The most cost-effective retrofit solution for this building consisted of using fiber composite wrap around beams and columns in all the exterior frames.
