Abstract:A moment magnitude 7.9 earthquake struck Myanmar on 28th March, 2025. Timber structures constitute the predominant building type in rural areas of Myanmar, and observations from this earthquake indicate that they exhibited generally good seismic performance. Post-earthquake field investigations show that most timber structures did not suffer obvious seismic damage. This paper introduces the structural characteristics of traditional timber buildings in Myanmar and systematically summarizes and analyzes their seismic damage features. The principal observed damage modes include complete or partial collapse, joint damage, damage to timber members, and cracking of infilled walls. Furthermore, this study analyzes the underlying reasons for the relatively minor seismic damage observed in timber structures, focusing on structural configuration, material properties, and construction practices. A comparative analysis between timber structures in Myanmar and those in Yunnan Province, China, is conducted to identify similarities and key differences in seismic behavior. Based on the lessons learned from this earthquake, practical insights and recommendations are proposed to improve the seismic performance of timber structures in Yunnan Province.
