NSF #1537788: Enabling Next Generation Hybridized Wood Buildings for Resilient and Sustainable Construction

In this project, the seismic behavior and optimization of a hybridized self-centering wood system termed a CLT-LiFS that uses unbonded post-tensioning tendons, cross-laminated timber (CLT) rocking walls and light-frame wood systems (LiFS) were investigated to enable the design of tall wood buildings that are sustainable and resilient. In this system, the CLT panel anchored with unbonded post-tensioning are optimally combined with the light-wood frame system to exploit the beneficial features of each. While the unbonded post-tensioning in the CLT will self-center the system, the connections in the light-frame wood will provide the necessary energy dissipation. The studies on CLT-LiFS have shown their very good seismic performance with limit structural damage.
