Seizmic analysis of the Lešće dam

Basic characteristics of Lešćegravity dam (Croatia) and adopted numerical model for its seismic analysis is first shorty described. The presented model can simulate main nonlinear effects of concrete and foundation rock, as well as water-dam-rock dynamic interaction. The dam was originally calculated with acceleration of 0.1g.Later it was found that at this locality earthquake acceleration up to 0.141g can be expected. In this paper, the dam is analyzed for the action of the several earthquakes, as well as for the harmonic base acceleration, with maximum acceleration of 0.15g. Only the most unfavorable dam block was analyzed. Analyses show that this dam block has sufficient safety for possible earthquakes with maximum ground acceleration of 0.15g.
