Abstract
On January 2,2022,a MS5.5 earthquake occurred in Ninglang Yi Autonomous County,Lijiang City,Yunnan Province,with many houses of ethnic minorities settled here.These houses were mostly self-built,with uneven seismic capability,thus being damaged badly.Yongning Town was the epicenter of the earthquake,according to the emergency evaluation statistics,more than 60%of the houses were marked as temporarily suspended or unusable.These houses of ethnic minorities in this area lacked detailed information on construction technology and structure,but a relatively fixed layout and building style were formed in recent years.Based on the field survey and analysis of the damaged self-build house of the local minorities,the reason why these house were badly damsged is that the local self-build house exist construction defects,the advice for rebuilding and reinforcement can be offered to reduce economic losses in the future.This article targets the epicenter,the most damaged Yongning Town,analyzing the seismic damages of these houses from the aspects of structure and construction.关键词
