SEISMIC ANALYSIS OF IREGULAR REINFORCED CONCRETE COUPLING WALLS SYSTEMS CONSIDERING DUCTILITY EFFECTS

Abstract eng:
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 1998 (1999), ENV 1998 (2003) and Önorm B4015 (2002). 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 with standard requirements is presented in this paper. Dynamic parameters of the building structure are checked by experiment and the calculation model is modified on the basis of the experiment. The nonlinear analysis of the coupling system was realized in the program CRACK (Králik and Cesnak 2001) under system ANSYS for Kupfer’s failure condition and Červenka’s model of the concrete strength reduction.
