Cross-Laminated Timber (CLT) panelized construction is gaining worldwide popularity as a sustainable, lightweight, and rigid load-bearing material that is quick to erect on building sites. The inventor has added curvature to the load-bearing edges of a wall panel, assembled in multistory building construction, enabling the walls to act as self-centering pendulum isolators when subject to earthquake effects.
The rigid-body kinematics of rocking panels, anchored by ductile connections or post-tensioning, provide flexibility and effective means of hysteretic energy dissipation. This technology aims to further the possibilities of CLT rocking systems through the development of curved end bearings for wall panels, to induce pendulum motion. Such a system can decouple the building from ground motion, thereby isolating structures and reducing earthquake force demands.
