Dynamic Model Rupture Tests of Concrete Dams on Shaking Table

Abstract

The seismic safety evaluation of dam is always concerned by designers and researchers. Due to the limited field prototype observation data, the dynamic model failure tests become more effective means than numerical analysis to investigate nonlinear dynamic response and failure mechanisms of concrete dam. A large number of the tests had been performed in Dalian university of technology in china. This paper makes a detailed description on the dynamic model test on shaking table. The similitude rules are discussed, the model material is introduced, the procedure is described for the dynamic model test. Based on the PGA(peak ground acceleration) inducing the first tension crack at the model dam body, the response of prototype dam under strong earthquake can be assessed by the test.
