Evaluation of Earthquake-Induced Risks in Modern, Code-Conforming Reinforced Concrete Moment Frames

Abstract: The main objective of this study is to employ performance assessment procedure to evaluate earthquakeinduced risks in modern, code-conforming Reinforced Concrete (RC) moment frames in terms of collapse risk and possible financial losses. In order to accomplish this goal, a set of 15 archetype RC moment frames is evaluated in this study. The buildings are different regarding height and structural system ductility. The archetypes are assumed to be located in three zones with different levels of seismicity. The findings of the collapse assessment procedure indicate that the constraint of ASCE 7-05 for the lower limit of design base shear has the most significant impact and the ductility has the least influence on collapse risk. Also, it has been found that buildings located in the low seismicity zone have significantly lower levels of losses. Sensitivity analysis is employed to study the variations of earthquake consequences due to the variations in the design decisions
