Calculating development of cracks in roller-compacted concrete gravity dams based on self-adaptive finite element method in ansys software

Abstract

Using ANSYS mechanical APDL, the authors have developed a program to calculate formation of cracks and development of cracks in roller-compacted concrete gravity body dams based on self-adaptive finite element method with grid elements which are subjected to static and dynamic loading capacity. The reliability of the program has been validated through some experimental results found in the literature. Using the program, the authors have also carried out to calculate the crack development of Son La RCC dam under loading capacity combination of earthquakes. The results show some effects of the cracks development to the loading capacity of RCC dams.
