Abstract

Stochastic analysis of reinforced concrete (R-C) 3D shear wall-frame structures under seismic excitations with the emphasis on the analysis of stiffness and strength degradation due to plastic deformations is theoretically performed. As constitutive moment-curvature relation, the model of extended Roufaiel-Meyer for flexural behavior and for shear reversals Origin-Oriented hysteretic model have been examined by making some modifications for wall elements and frame members. Stochastic earthquake excitations are specified as intensity modulated to the Jennings-Housner-Tsai type envelope function and Gaussian white noise filtered simulated earthquake. Dynamic equation of motion is formed as an equivalent first order Stratonovich stochastic differential equation. In order to reduce the calculation time during extensive simulations, a system reduction scheme have been implemented. Demonstrating the ability of the program to predict the actual seismic response, a 7 storey R-C wall-framed full-scale test structure has been calculated and the results are successfully compared with the experimentally recorded data.
