Abstract

This research presents the nonlinear analysis model for reinforced concrete shear wall systems with special boundary elements asproposed by the Korean Building Code (KBC, 2009). In order to verify the analysis model, analytical results were compared with theexperimental results obtained from previous studies. Established analytical model was used to perform nonlinear static and dynamicanalyses. Analytical results showed that the semi-special shear wall improved significantly the performance in terms of ductility and energydissipation as expected based on previous test results. Furthermore, nonlinear incremental dynamic analysis was performed using 20ground motions. Based on computer analytical results, the ordinary shear wall, special shear wall and newly proposed semi-special shearwall systems were evaluated based on the methods in FEMA P965. The results based on the probabilistic approaches accounting forinherent uncertainties showed that the semi-special shear wall systems provide a high capacity/demand (ACMR) ratio owing to theirdetails, which provide enough capacity to sustain large inelastic deformations.
