Seismic Mitigation Strategies for Existing School Buildings Which Are Subject to Earthquake Risk Throughout the United States

在美国，减少学校建筑地震危害的工作由加州负责。加州学校取得的成功被许多人认为是通过提高建筑物和设施的地震安全性来最大限度地减轻灾害的一个很好的例子。许多研究人员致力于减少加州以外的地震危害，包括2号和3号地震带，正试图学习加州的经验，并传播其优点。该项目解决了与物理设计过程和将公立学校的抗震改造与其他一般维护操作相结合的研究问题。处理学校整体设施管理的组织规划。解决这两组问题是为了在现有学校制定一项全面、可行的减轻地震危险战略。该项目分为三个组成部分。第一份报告审查了地震暴露的状况和目前在地震带2和3的8个选定辖区内学校设施的维护和改造程序。第二部分是对过去50多年来加州在学校减少地震危害方面的经验进行回顾和分析，以更好地理解经济、政治、以及促进项目完成的行政因素。该项目的第三部分是基于对当前维护和改造程序的分析以及加利福尼亚的专业经验，以制定经济上可行和社会上可接受的指导方针现有学校建筑减少地震危险的策略。

The lead for earthquake hazard mitigation in school buildings in the U.S. is provided by California. The success achieved with schools in California is considered by many to be an excellent example of hazards mitigation at its best by increasing the seismic safety of buildings and facilities. Many researchers addressing seismic hazards mitigation outside of California, including Seismic Zones 2 and 3, are attempting to learn from the California experience and promulgate its merits. This project addresses research questions related to the physical design process and the integration of seismic retrofit of public schools into other general maintenance operations, dealing with the organizational planning of overall school facilities management. Both sets of issues are addressed in order to develop a comprehensive, viable strategy for seismic hazard mitigation in existing schools. The project is divided into three component parts. The first examines the status of seismic exposure and current maintenance and retrofit procedures of school facilities in eight selected jurisdictions in Seismic Zones 2 and 3. The second is a review and analysis of the California experience of seismic hazard reduction in schools over the past 50-plus years to better understand the economic, political, and administrative factors which facilitated program completion. The third component of the project is based on the analysis of current maintenance and retrofit procedures and the specialized California experience to develop guidelines for economically feasible and socially acceptable strategies for seismic hazard reduction in existing school buildings.
