Seismic events pose a significant threat to infrastructure, particularly to large-scale concrete gravity dams, which are prevalent in the western United States. This project focuses on the dynamic analysis of such structures, specifically the Chili Bar Dam, using SAP2000. The study involves the development of a finite element model to evaluate the dam's response to seismic loading through time history analysis. By examining the influence of different intensity measures on structural behavior, the project aims to improve the accuracy of seismic performance predictions. Given the complexity of dam modeling in SAP2000, initial challenges included excessive data points slowing computational efficiency and difficulties in properly importing CAD models. To address these issues, alternative modeling techniques and software solutions are being explored. The findings from this research contribute to a better understanding of seismic risks for Chili Bar Dam and similar structures, aiding in more effective engineering design and retrofitting strategies.
