| The research on non-linear analysis for concrete dams using the smeared crack model has been conducted. Efforts to verify applicability and accuracy of such numerical analyses for concrete dams have been made through simulations for actual damages of existing concrete dams due to large earthquakes. But a more quantitative evaluation of the cracking process of unreinfoced concrete mass such as concrete dams using crack analysis is needed in order to use numerical analysis method to estimate the limit state of concrete dams during large earthquakes.In this study, shaking table tests ware conducted to investigate the effect of cracks on the dynamic behavior of unreinfoced concrete structures. A numerical analysis was also attempted in order to simulate cracking in the test models by finite element analysis using the smeared crack model. |
