NONLINEAR MODELING OF RC AND SRC STRUCTURAL WALLS
ABSTRACT
Prediction of the inelastic response of RC and SRC walls and wall systems requires a reliable modeling approach that includes important material and response parameters (e.g.,confinement, slip, nonlinear shear behavior, neutral axis migration).
Although various macroscopic models have been proposed to evaluate the response of RC walls, the models are not available in commonly used analysis programs. A research project was undertaken at UCLA to investigate and to improve on an effective modeling approach for the reliable prediction of the inelastic response of RC and SRC walls that incorporates refined constitutive laws and various response parameters. The Multi-Component-in-Parallel Model is being calibrated and updated using extensive experimental data on RC and SRC walls, and will be implemented into a widely available analytical platform. The objective of this paper is to summarize the ongoing analytical project and to discuss the effectiveness and reliability of the model for RC walls. Model calibration with experimental data and investigation of model sensitivity to modeling parameters are emphasized.
