Sažetak
The paper first briefly describes the numerical model for the numerical simulation of the fluid-structure coupled problems. The primary intent of the applied model is to simulate the fluid-structure dynamic interaction in seismic conditions. The partition scheme of the coupled (multi-field) problem is briefly described as the most common approach for the fluid-structure dynamic analysis of large systems. The developed model includes the most important nonlinear effects in water and structure, such as concrete yielding in compression and crack opening/closing in tension, reinforcement yielding and the phenomenon of cavitation in water. Next, an analysis of the seismic behaviour of the Grancarevo concrete arch dam is performed. The complex model of the water-dam-foundation rock system is analyzed for the registered earthquake from 1986. The analysis was conducted in order to first determine the dynamic characteristics, and then to investigate the actual behaviour of the dam subjected to seismic excitation. The numerical results of the developed numerical model were compared with the registered values.
