INVESTIGATING THE SEISMIC PERFORMANCE OF WOOD-FRAMED SHEAR WALL WITH ADVANCED CONNECTION SYSTEMS IN STRUCTURAL WOOD DESIGN AND ENGINEERING

Abstract

Wood-framed buildings are popular for residential and commercial construction due to their sustainability, costeffectiveness, and aesthetic appeal. However, their seismic performance is a concern, particularly in earthquakeprone regions. This study investigates the seismic performance of wood-framed buildings with advanced connection systems. The research evaluates the structural integrity and resilience of wood-framed buildings subjected to seismic loads. Advanced connection systems, including innovative fastening techniques and reinforced connections, are analyzed to determine their effectiveness in enhancing the seismic performance of wood-framed buildings. The study aims to provide valuable insights for designers, engineers, and builders to improve the seismic resilience of wood-framed buildings.  seismic performance of wood-framed buildings, advanced connection systems, and structural wood design. Determine areas requiring further investigation. The fundamentals of displacement-based seismic design are presented along with a description of the system parameters required for its application. A simple numerical model capable of predicting the cyclic response and energy dissipation characteristics of wood shear walls under general quasi-static cyclic loading is presented to evaluate these parameters for wood-framed buildings. The generalization of this model to three-dimensional wood-framed structures is also discussed. As an application example, the displacement-based seismic design of a simple one-story shear wall building is presented. In turn, this design approach is validated by nonlinear dynamic time-history analyses using earthquake records representative of the hazard levels associated with the design performance levels.
