Performance-Based Design of Coupled Wall Systems
Coupled core walls offer an efficient lateral load resisting system. Performance of coupled wall systems depends primarily on ensuring that coupling beams provide adequate stiffness and strength. Current design guidelines, which are based on a strength-based design approach, often result in beams with unrealistic details. Previous studies have also demonstrated that coupled core walls behave differently from what is assumed in a traditional strength-based design approach. Therefore, currently available strength-based design methodology is inadequate to address a large class of coupled core wall systems, and alternative design approaches are necessary. In this paper, a rational approach based on a performance-based design method is demonstrated through the design and analysis of a prototype ten-story coupled core wall structure. Critical responses of the prototype structure at different limit states under a number of representative ground motions are compared in order to evaluate the adequacy of the performance-based design method.
