石结构房屋抗震防灾关键技术研究与展望

我国东南沿海地区现存的大多数石结构房屋的整体性和抗震能力极差,存在＂小震成灾、小震大灾＂的隐患。本文分析了石结构房屋的构造特点和存在的主要抗震薄弱环节,评述了已有石结构研究的主要工作及存在问题,明确了现代石结构研究应围绕＂有效减轻区域重大灾害＂和＂利用创新科技保护并发扬传统石结构文化＂这两个中心任务开展。提出了石结构防灾及现代石结构的研究框架,并介绍了基于该研究框架下的石结构抗震防灾研究工作的最新进展。

Study and Prospect of Disaster Prevention Technology of Stone Masonry Structures

Most stone masonry houses in southeast coast of China have poor seismic behavior,so the potential risk of these buildings against earthquakes,even with low intensity,would be serious.This paper analyzes the structural characteristics and the main weakness of stone masonry structures.The state-of-the-art of the studies and problems are also discussed.It is indicated that the two main task of modern stone structure research are disaster mitigation and preservation and development of the culture of stone build...
