“…All other structural elements in the steel braced frame are designed to remain elastic using the capacity design philosophy. The GLRS consisting of timber is designed to carry the gravity load while reducing the seismic weight of the structure that is resisted by steel CBFs, resulting in a light seismic force-resisting system as compared to a structure with a floor system consisting of concrete [13]. In the proposed structural system, the timber joints are developed with a pure hinge.…”

This study evaluates the seismic response of an advanced hybrid steel‐timber structure using a nonlinear static and dynamic analyses. A three‐story prototype building located in Vancouver, BC, Canada was designed first. The gravity load resisting system (GLRS) consists of cross‐laminated timber (CLT) floor slabs, glulam beams, and glulam columns. The lateral load resisting system (LLRS) includes a chevron‐type steel Concentrically Braced Frame. The numerical model of the structure was then developed in the OpenSees program. Nonlinear hysteresis response of steel braces and timber joints were explicitly simulated. The results of the analysis revealed that the hybrid structure possess an acceptable lateral stiffness while providing sufficient ductility to dissipate seismic energy. No unsatisfactory response was observed in the timber system.
