Seismic Protection Technologies

Taller timber buildings (TTBs) offer sustainability benefits but pose unique seismic challenges. The following chapter reviews state-of-the-art seismic protection technologies (SPTs) for TTBs, including low-damage self-centering systems, post-tensioned systems, supplemental damping systems, passive and active control systems and base isolation. It discusses the principles, applications, and future challenges of each technology. While significant progress and innovative solutions have been achieved, outstanding challenges include scaling the technology, optimizing cost-effectiveness, and managing interactions between structural and non-structural elements to enhance functional recovery, damage limitation, and acceleration reduction. By examining current practices and future directions, this review facilitates a broader understanding and implementation of SPTs, promoting the sustainable growth of TTBs in seismic-prone regions.
