    摘要:

    云南省境内共有五种常见的木结构民居,不同木结构的抗震能力受风俗习惯、气候条件、经济水平等因素影响。通过大量的实地调查及对往年地震中房屋震害的总结,展示了各类木结构的分布情况和结构特征,总结了各类木结构的震害特征,并对往年地震中各类木结构的震害损失进行统计分析。结果表明,木结构震害带来的经济损失在民房经济损失中占很大比例,木结构的抗震能力已无法满足现行抗震设防要求,木结构非承重构件极易在地震中损坏,木框架也难以抵御大震。

    Abstract:

    In Yunnan Province,five distinct types of residential timber structures are identified. The seismic resistance capabilities of these structures vary significantly due to factors such as traditional construction methods,local weather conditions,and economic constraints. Based on extensive investigations and historical seismic damage data,this article presents a comprehensive analysis of the distribution and architectural characteristics of timber structures in Yunnan. The seismic damage patterns for each type of structure are summarized,and detailed analyses of historical earthquake damage data reveal that the economic losses associated with damaged timber structures constitute a substantial proportion of the total residential housing losses in Yunnan earthquakes. The findings indicate that the existing timber structures in Yunnan no longer meet the current seismic fortification requirements. Non-load-bearing components are particularly susceptible to damage during seismic events,and the timber frames themselves struggle to withstand significant seismic forces.
