This project investigates the seismic analysis of post-tensioned concrete gravity dams. To achieve this, we utilized ABAQUS CAE with the UEL (User Element) subroutine. The project enhances the simulation of complex structural interactions, including inclined anchors and weak joints, which are crucial elements in concrete gravity dam design. Specifically, it provides a detailed comparison between transient and pseudo-static analysis results. This comparison is essential for understanding how the dynamic responses and structural behavior of these dams under seismic conditions can be effectively modeled and validated within the broader scope of concrete gravity dam design. Moreover, the project offers insights into potential debonding issues and their impact on post-tensioning forces, which are critical considerations in concrete gravity dam design. This research benefits civil engineers and academics by advancing the methodologies used for designing and analyzing the resilience of gravity dams, particularly in earthquake-prone regions.
