Optimal design and earthquake-resistant design evaluation of low-rise framed RC structure
Rights accessOpen Access
This study evaluates the seismic response of an existing two stories RC building using non-lin-ear analysis. The original model was resized and two buildings were designed using two different methodologies to fulfill the Venezuelan codes requirements for a high seismic hazard. An elas- tic analysis was applied to the original building in order to verify interstory drifts; the resizing building was designed under requirements of strong column-wake beam condition. A third building was modeled according to the seismic displacement-based design procedure. A non- linear static analysis and 2D and 3D dynamic analyses were performed, obtaining capacity curves, structural ductility, structural perform-ance point, global and interstory drifts for each building. Torsional effects for the resizing building were also computed from 3D analysis. In the original building a weak seismic behavior was obtained, while resized buildings presented a good seismic performance under the Limits States evaluated in this study.
