Research on Seismic Performance of Traditional Chinese Ganlan Timber Structure: A Case Study of Tujia Village in Western Hubei Province
The traditional Ganlan timber frame (pile-built timber construction) is a typical construction widely used in the vernacular architectural heritage in Southeast Asia. It is built to adapt to the warm and humid climate and complex mountain terrains. The traditional Chinese Ganlan buildings are primarily distributed in the region with high seismic hazards, and the complex construction system makes accurate seismic performance evaluation a difficult task. Taking Ganlan building of Tujia village in southwest Hubei Province as an example, an efficient and scientific performance-based seismic evaluation method is proposed. First, the geometric information of Ganlan buildings is obtained from three-dimensional scanning and on-site investigation. The established finite element models are modified through low-cycle cyclic loading tests of mortise and tenon joints. Then, to quantify the global seismic performance levels of the structures, the nonlinear static pushover method is used to analyse the seismic performance of the Ganlan building, and the dynamic characteristics and story drift ratios of the structure under three working conditions are obtained. Finally, the local failure modes of the structure are determined by order of modified plasticity hinges generation. The research results can provide a scientific basis for the structural performance research and subsequent reinforcement research of Ganlan buildings.
