Abstract
The paper presents a model for numerical simulation of interaction between the fluid and the reinforced-concrete structure under seismic load for spatial 3D problems, with an emphasis of concrete dams. The model is based on the so called partition scheme for coupled (multi-field) problems. The model especially focuses on the concrete ageing effects, which has proven to be highly significant in the analysis of older structures. The paper starts with a brief description of the numerical model, which is followed by a more detailed description of the concrete ageing model, and by analysis of Jablanica hydropower plant (HPP) on which the validity of the model and related software was checked.
