Risk-based Estimation of Reparability for a Reinforced

[[abstract]]This work assesses seismic damage to a reinforced concrete (RC) building using a simplified novel method that considers the hazard curve of response spectral acceleration of a specified site. Moreover, we assume the time earthquake events occur follows a Poisson process when analyzing the cumulative probability curve of lifetime repair costs for seismic damage in an RC building’s service lifetime. The mean value of lifetime seismic repair costs is then regarded as an index representing building reparability, which includes repair costs incurred by cumulative damage. Via this estimation procedure, the mean value of lifetime seismic repair costs and initial construction cost of a selected building can also be used to help building owners manage their assets. Moreover, according to mean values of lifetime seismic repair costs in terms of ultimate ductility ratios and yield accelerations for the single degree of freedom system of an RC building obtained by the proposed method, one can consider seismic codes and the required lifetime reparability performance in the preliminary seismic design stage for a building. Finally, this novel procedure for estimating lifetime repair costs incurred by seismic damage is then applied to a case study to demonstrate its applicability
