High-Performance Timber Frames with Smart Braces
As the number of stories and height of wood buildings increase, the lateral loads become significantly important in design considerations. Using moment frames in tall timber structures (i.e., buildings beyond six stories) becomes uneconomical as the member sizes have to be increased significantly to provide sufficient lateral stiffness to the structure to resist seismic load effects. A robust, yet cost-effective and practical solution to improve lateral stiffness of tall timber structures is to add a braced frame so that a novel advanced structural system is developed for practical applications. For tall timber structures in seismic regions, the concept is of considerable interest due to demand for compact arrangement and efficient lateral load-resisting system exhibiting inherent high stiffness and subsequent reduction in drifts. This paper examines the applicability of the proposed structural system in timber buildings through determination of the influential parameters on the seismic response of the proposed “Smart” system with Shape Memory Alloy (SMA) dampers used in braces. The elastic nature of SMA contributes to self-centering performance of the overall system. A robust numerical model of the frames incorporating the SMA dampers is developed and used to recommend optimized configuration practical designs.
