Parameters for Performance Based Design of Mid- and Low-Rise RC Structural Walls

Abstract

The current building design codes are generally based on a strength-based design philosophy A building designed according to such approaches has unpredictable seismic responses Performance-based design approaches which are recognized as advanced design methods for the next generation allow engineers to design a building with the pre-determined structural performance objectives under varying seismic hazard levels A key element to a successful performance-based design is an adequately defined framework of performance limit states In addition a direct approach to accurately identify the performance limit states of structures with different designs is also necessary when implementing the performance-based design The object of this article is to propose a model for predicting the displacement demands associated with the performance limit states of RC structural walls The model is developed using regression analysis on the extensive seismic responses obtained using 3D finite element RC structural wall models Existing experimental results of RC structural walls under cyclic loading are employed to validate the proposed model The comparisons between the experimental results and the predicted solutions show good agreements
