Seismic performance evaluation of ancient Tibetan residential structures and energy dissipation of Mortise-Tenon Joints
Jie Tang, Jingran Xu, Dewen Liu
TL;DR
This paper evaluates how ancient Tibetan houses withstand earthquakes, focusing on the role of earth walls and different joint types in energy dissipation.
Contribution
The study introduces a comparative analysis of Tibetan residential structures' seismic performance using theoretical and finite element methods.
Findings
Earth walls significantly improve the stiffness and seismic stability of Tibetan timber frames.
Through-tenon joints show better energy dissipation than straight tenons due to fuller hysteresis curves.
Abstract
Tibet, situated in western China, is renowned for its highland landscape, rich culture, and profound religious heritage. Tibetan-style ancient houses, typical dwellings in this region, reflect the Tibetan people’s adaptation to the plateau environment and hold significant cultural, historical, and ecological value. This study used theoretical and finite element analyses to compare the seismic performance of Tibetan houses under various conditions. It evaluated the effects of three types of seismic waves—with and without earth walls—having peak accelerations of 0.4 g and 0.6 g, focusing on interstory displacement angles and top accelerations. Finite element analyses were also conducted on through-tenon and straight-tenon joints to examine stress distributions and hysteresis curves for transverse and smooth grain orientations. Results showed that earth walls significantly enhanced the…
