Performance of concrete gravity dam with various height of dam based on static pushover analysis

Abstract

The study was related to the performance of the concrete gravity dam with a various height of dam based on static pushover analysis. Based on the concepts of nonlinear static pushover analysis, a lateral incremental load is applied to the dam body after exerting gravitational and hydrostatic loads. In a concrete gravity dam, inertia loads and hydrodynamic loads are the types of lateral loads generated in earthquakes. The four concrete dams of various height had been analyzed by using ABAQUS. For each model, there were 10 trials analysis of increasing lateral load until the dam reached its limit state. The four finite elements of the concrete gravity dam with various height will be designed. The various height of concrete gravity dam has been specified to 50m, 75m, 100m and 125m. The analysis had been run and the limit state of concrete gravity dam such as cracking will be determined. The magnitude of lateral pushover load will be increased consequently until the dam reached its limit state.
