Fracture analysis of concrete gravity dam under earthquake induced loads
In this paper, seismic fracture behavior of the concrete gravity dam
using finite element (2D) theory has been studied. Bazant model which
is non-linear fracture mechanics criteria as a measure of growth and
smeared crack was chosen to develop profiles of the crack. Behavior of
stress - strain curves of concrete as a simplified two-line, dam and
reservoir system using the formulation of the Euler - Lagrange was
chosen. According to the above models, Koyna concrete gravity dam were
investigated by the 1967 earthquake record. The results provide
profiles of growth and expansion first with the effects of reservoir
and second without it. Comparison of the obtained results shows good
agreement with the works of the other researchers
