This paper presents results of experimental and numerical analysis of seismic resistance of reinforced concrete coupling system considering the plastic capacity in accordance of standard requirements STN ENV ), ENV ), Önorm B) and FEMA ). The plastic capacity of the structure can be established by parameter q in the case of the spectral analysis to determine the seismic response. The experience from dynamic analysis of a hospital structure in accordance

The optimal control problems and a weight minimization problem are considered for elastic three-layered plate with inner obstacle and friction condition on a part of the boundary. The state problem is represented by a variational inequality and the design variables influence both the coefficients and the set of admissible state functions. We prove the existence of a solution to the above-mentioned problem on the basis of a general theorem on the

This paper gives the results of earthquake response analysis of nuclear power plant buildings in accordance with the methodology of seismic margin assessment and generic implementation procedure. Earthquake resistance of all the important buildings was considered taking a dynamic effect on soil-structures interaction (SSI) into account. The stiffness and damping values of simple soil model were compared. Limits of seismic resistance of buildings
