Abstract
SUMMARYThe study concentrated on investigating the relationship of the continuous cumulative damage, macroscopic deformation development and failure process of mid‐rise shear walls. Nonlinear fiber element model considering the effect of cumulative damage is proposed for evaluating the seismic performance of shear wall. Numerical analyses of shear wall specimens are carried out according to the proposed model to obtain the evolution of damage index of the shear wall. Experiments of six L‐shaped shear wall specimens subjected to reversed cyclic loading are carried out to verify the proposed model. Correlation of damage index and performance level is established, which provides good reference for the safety assessment of the structure under seismic type of loading. The model is efficient to evaluate the seismic performance of shear wall proved by the satisfactory agreement between analytical and experimental results. Copyright © 2012 John Wiley & Sons, Ltd.
