Seismic Analysis of Pine Flat Concrete Dam

Su, W. / Wang, J.-T. / Xu, Y.-J.

This paper focuses on the Theme A of the 15th International Benchmark Workshop on Numerical Analysis of Dams. The seismic analysis of Pine Flat Concrete Dam proposed by formulators is performed by the Finite Element Method. And several two-dimensional FE models are established for the case studies. All the obligatory and optional cases have been completed, including Case A for EMVG test simulation, Case B for foundation analysis using impulsive loads, Case C for dynamic analysis using impulsive loads, Case D for dynamic analysis using Taft records, Case E for non-linear dynamic analysis, and Case F for dynamic analysis using massless foundation. Results show that the effect of reservoir level is notable in EMVG Test Simulation, and the exist of dam can influence the dynamic response on the top of foundation. Besides, the weak parts of the gravity dam body against seismic are dam heel, dam toe, dam neck, and the upper part of downstream dam body, and dynamic responses computed in model with massless foundation are overestimated.
