Prefabricated Multistory Structure Exposure To Engineering Seismicity By Using SAP

ABSTRACT The paper investigates the inelastic seismic response of contemporary multi-story Reinforced Concrete (RC) buildings to a number of seismic scenarios applicable to medium seismicity regions of the Middle East. Four RC buildings are considered, representing regular and irregular ductile Moment-Resisting Frame (MRF) structures. These are designed and detailed according to two design provisions employed in this region. A verified analytical tool and refined fiber modeling approach able to simulate the cyclic response of structural members are adopted. The seismic response from extensive dynamic collapse analyses is monitored on the member and the structure levels for a diverse set of input ground motions. Investigating the inelastic response of the buildings designed to the two design provisions provides insight into the behavior of structures designed to different levels of force reduction factors. It also offers international calibration to the national design codes in the region and aids in understanding the differences and similarities with international design provisions. This helps to improve the design codes, which is the most effective mean to reduce earthquake losses and increase public safety.
