Abstract :
The design and evaluation of concrete gravity dams will be studied in the present study. The case study consists of a comparison between old research methods and new ones. In the present case, an analysis of concrete gravity dams with different water levels influenced by earthquake will be presented. The subject of the study is a concrete gravity dam project by Rolling Compact Concrete (R.C.C), which is to be located 30 kilometers away from the South East of Sanandaj named Jaweh. It would be the second R.C.C dam made in Iran. The data used in the study is collected from detective. One of the investigation methods is a simplified one by Chopra and Feneves, which is based on a pseudo dynamic method. The new investigation method is conducted on the basis of finite element. Abaqus and Cadam Softwares are based on finite element method as well. This essay investigates the effect of linear behavior of concrete gravity dam with different water levels on rigid and flexible foundation. Afterwards the effect of non-linear behavior of concrete gravity dam on tensil cracking will be investigated and cracking seems directions will be studied by three earthquake accelerators.
