Performance Based Rapid Seismic Assessment Method (PERA) for Reinforced Concrete Frame Buildings

摘要: Recent destructive earthquakes have shown that many existing buildings, particularly in developing countries, are not safe against seismic actions. Since code-based safety evaluation methods generally require detailed and complex structural analysis, the necessity for simplified, yet sufficiently accurate emerges reducing cost duration of assessment procedures. In this study, a performance based rapid method (PERA) is proposed reinforced concrete buildings. The overall determined on demand/capacity ratios individual columns, as well their failure modes (brittle/ductile), confinement characteristics, levels axial shear stresses. lateral drift critical story, calculated through simplified approach, also taken into account during determination global performance. predictions compared with results conventional saf...
