Abstract
For performance-based design using nonlinear static analysis. it is required to predict the inelastic behavior of structural members accurately. In the present study, a nonlinear numerical analysis was performed to develop the method describing the moment-curvature relationship of structural wall with boundary confinement. Through the numerical analysis. variations of behavioral characteristics and failure mechanism with the arrangement of vertical reinforcement and the length of boundary confinement were studied, According to the analysis. the maximum moment-carrying capacity of structural walls with adequately confined boundary elements is developed at the moment the unconfined concrete reaches the ultimate compressive strain, Walls with flexural re-bars concentrated on the boundaries fails in a brittle manner. As vertical re bars in the web increases. the brittle failure is prevented and a ductile failure occurs, Based on the findings. moment-curvature curves for walls with a variety of re-bar arrangement were developed, According to the proposed relationships. deformability of the structural walls wth boundary confinement increases as the compressive strength of the confined concrete increases compared to the applied compressive force.
