| 摘 要： | 本文整理了云南大理州"5.21"6.4级地震震害调研与科考过程的部分成果。穿斗木架构结构和框架结构是云南大理州在低矮建筑和多高层建筑中广泛应用的两种结构形式。该研究基于震害调查结果，描述了地震过程中穿斗木架构结构和框架结构破坏的宏观现象，总结了两种典型结构的破坏形式，对震害成因进行了探讨。在此次震害调查过程中，科考人员还通过智能手机对结构基频进行了快速评估。在震后，研究人员对智能手机智能测振应用软件进行了更新，结合应用需求加入了测振地点和路线的地图信息，为震害调查与记录提供了便利。基于漾濞县震害科考与调研结果，为云南省穿斗木架构建筑及框架建筑的抗震方法与策略提出了建议，为震后建筑结构快速评价提供了新手段。

| Abstract: | This paper introduced some results of the earthquake damage investigation and scientific research process of the "5.21" Yangbi M6.4 earthquake in Dali Prefecture, Yunnan Province. Chuandou type timber frame structures and reinforced concrete frame structures are two kinds of building structures widely used in low buildings and multi-storey and high-rise structures in Dali Prefecture, Yunnan Province. Based on the investigation results of earthquake damage, this study describes the macro phenomenon of the failure of Chuandou type timber frame and reinforced concrete frame structure in the process of earthquake, summarizes the failure forms of the above two typical structures, and discusses the causes of earthquake damage. During the earthquake damage investigation, the researchers also evaluated the fundamental frequency of the structure through smart phones. After the earthquake, the researchers updated the smart phone intelligent vibration measurement application software, added the map information of vibration measurement location and route which will support the earthquake damage investigation. Based on the results of M6.4 earthquake damage scientific research and investigation in Yangbi, some suggestions are summarized for the seismic design methods and strategies, and a new tool is developed. |
