A comprehensive specimen database was constructed using data from various studies, encompassing diverse material properties and geometric parameters of RC components. The OpenSees software was utilized to build and validate shear wall models, ensuring accurate simulation of dynamic behavior under seismic loading. Using a probabilistic seismic risk assessment method, this research provides detailed analysis of buildings′ seismic performance under different earthquake scenarios. Fragility curves were developed to reflect the damage probability under varying seismic intensities. The results indicate that the automated tool can swiftly and accurately evaluate seismic risk, providing damage predictions and repair recommendations. This study also examines the impact of different seismic characteristics on the performance of RC shear walls. The findings demonstrate the tool′s reliability across various scenarios, reducing time and errors associated with manual calculations while enhancing assessment efficiency and accuracy. In conclusion, this research offers a scientific basis for the seismic evaluation of RC buildings in Taiwan and showcases the potential application of the automated tool in seismic risk assessment. These outcomes will assist relevant departments in making more informed and effective decisions in earthquake disaster prevention and mitigation.
