SEISMIC BEHAVIOR AND PERFORMANCE FOR SINGLE-STORY GRAVITY-DRIVEN CLT ROCKING SYSTEM

Abstract

This paper proposes a gravity-driven CLT rocking system with hardware commonly used in conventional Japanese houses as an alternative to high-ductile hardware in CLT panel construction. The system ensures no damage during moderate seismic events and relies on rocking restoring forces to prevent collapse during maximum considered earthquakes. Shaking table tests on full-scale, single-story CLT buildings evaluated this design concept. Results showed specific seismic behaviors such as shear force surges and compliance with the Japanese Building Code. Furthermore, the influence of two-dimensional excitation, the connections with walls, wall arrangements with eccentricity, and exterior wall followability were evaluated.
