Seismic analysis of reinforced concrete frame-wall systems considering ductility effects in accordance to Eurocode

摘要

This paper presents the results of experimental and numerical analysis of the seismic resistance of a reinforced concrete coupling system considering the plastic capacity in accordance with the standard requirements STN ENV 1998 (2005), ENV 1998 (2003), OEnorm B4015 (2002) and FEMA 368 (2001). 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 under system ANSYS for Kupfer's failure condition and Cervenka's model of the concrete strength reduction.
