Displacement-based Design of Hybrid Steel-timber Structures

Driven by heightened environmental awareness, the construction industry increasingly strives to utilize materials such as timber with a low-carbon footprint in their life cycle. High-strength mass-timber products, innovative ductile connections, and fast computer-numerically-controlled pre-fabrication, combined with changing legislation create better opportunities to also build tall timber structures. However, low ductility and limited tensile strength of timber are challenges for such buildings particularly in high seismic zones. By contrast, steel exhibits high ductility and tensile strength; the hybridization of steel and timber is an intriguing solution that offers new design opportunities. Current codes and standards, however, do not provide any design guidance for timber-steel hybrid structures. Displacement-based design (DBD) in which the seismic design problem is reduced to the evaluation of the allowed displacement and required strength that ensures all performance objectives are satisfied, has been identified as a promising approach.
