SEISMIC VULNERABILITY OF A REINFORCED CONCRETE BUILDING USING THE CAPACITY SPECTRUM METHODOLOGY

Abstract

The designs carried out, following the requirements of the Seismic Resistant Standards, should present low Vulnerability and be more reliable in the face of seismic threats different from that of the design; but recent seismic events have shown the opposite, so it is necessary to evaluate the Seismic Vulnerability of structures based on the control of the Dynamic response. In this study, the Seismic Vulnerability of a reinforced concrete framed building was determined against three levels of seismic threat (service, design and severe earthquakes), using the methodology proposed by ATC-40, or the Capacity Spectrum methodology through an analysis Pushover, which resulted in this building, has the capacity to withstand a severe earthquake (Aa =0.15g), although the first floor beams are in the range of collapse, so its reinforcement is recommended.
