Shaking Table Test and Numerical Simulation Study of the Reinforcement Strengthening of a Dam

This paper presents experimental and numerical investigations of the seismic failure reinforced unreinforced monoliths Huangdeng concrete gravity dam. To verify scale factors, we use suitable materials (emulation material fine alloy wire) to simulate dam steel reinforcement (SR) in a scaled experiment model that includes water-retaining monolith overflow We design shaking table tests based on similarity laws perform nonlinear simulations damage By comparing simulation with results, intervals for peak acceleration, which microcracks appear macrocracks rapidly expand, are obtained. The modal distribution results proposed method SR. analyzing reveal crack resistance mechanism research provides rational foundation further study dams.
