Implications of Codes Governing the Strengthening of Unrein-forced Masonry Buildings

这是一个事后调查项目，旨在从1989年10月洛马普列塔地震中吸取工程教训。本项目旨在收集、分析和解释与Loma Prieta地震中未加固砌体（URM）建筑性能相关的技术和减灾数据。所收集的性能数据将用于《SEAOC/CALBO接缝无加筋砌体技术加固规定》的改进。这些规定最近已被加州结构工程师协会（SEAOC）批准，并提交到《建筑保护统一规范》（UCBC）中。如果得到国际建筑官员理事会的批准，它们将为URM建筑的减灾提供统一的设计标准。该数据库可以通过补充、澄清、以及有效实施所必需的改变。这些改进将被制定，以提供相关的补充评论和示例应用。该项目将对改进抗震规范条款作出重要贡献。

This is a post-event investigation project to learn engineering lessons from the Loma Prieta earthquake (October 1989). This project is to collect, analyze, and interpret the technical and hazard mitigation data related to the performance of unreinforced masonry (URM) buildings in response to the Loma Prieta Earthquake. The collected performance data will be applied to the improvement of the "SEAOC/CALBO Joint Unreinforced Masonry Technical Strengthening Provisions." These provisions have been recently approved by the Structural Engineers Association of California (SEAOC) as a submittal for inclusion in the Uniform Code of Building Conservation (UCBC). If approved by the International Council of Building Officials they will provide unified design criteria for the hazard mitigation of URM buildings This data base can provide valuable improvements to these new provisions in the form of additions, clarifications, and changes necessary for their effective implementation. These improvements will be formulated to provide the related supplementary commentary and example applications. This project will make an important contribution to the improvement of seismic code provisions.
