Workshop to Identify and Establish Priorities for NEES Research on the Seismic Vulnerability of Existing Buildings; Spring 2007

应用技术理事会(ATC)是加州的一家非营利性公司，成立的目的是将结构和地震工程研究成果综合并转化为积极的工程实践。该委员会将举办一次研讨会，以确定现有建筑的地震脆弱性研究的优先事项，该研究可以利用国家科学基金会资助的小乔治·E·布朗进行。地震工程模拟网络(NEES)基础设施。这次研讨会将收集全国结构和岩土工程专业人员的建议，并将由地震工程研究所(EERI)联合组织，联邦紧急事务管理局(FEMA)提供资金。联邦应急管理局的资金将用于扩大讲习班的范围，以确定与以下方面有关的关键问题：(1)短期实施和更新现有建筑物的震后修复指南；(2)长期发展和加强震后恢复指南。这次研讨会是对国家减少地震灾害计划(NEHRP)具有重要战略意义的重大协调努力。本次研讨会还讨论了美国竞争力倡议：引领世界创新，国内政策委员会，科学和技术政策办公室，2006年2月概述的11个研究目标之一：“材料科学和工程的进步，以开发在地震和飓风等危险事件中改善结构性能的技术和标准(NIST，NSF)。”研讨会的一个主要成果将是研讨会的调查结果报告，其中列出了现有建筑上所需的NEES研究工作的优先次序。讲习班报告将由一个ATC工作组编写，该工作组是讲习班指导委员会的一个子集。在联邦应急管理局的资助下，讲习班指导委员会的另一个分支--EERI工作组将编写一份类似的报告，重点讨论如何加强制定和实施现有建筑物的地震修复指导方针。这次讲习班的学术价值在于，就减少现有建筑物的地震脆弱性的NEES研究工作的优先事项建立明确的基于社区的战略指导。目前现有的确定地震工程研究需要的资源文件仅就这一专题提供了广泛的指导，并没有确定国家地震研究基础设施能够独一无二地解决的研究问题的具体优先事项。位于美国地震活跃地区的许多现有建筑尚未进行评估或加固。缺乏基本的和以问题为中心的研究数据导致现有评估方法严重保守，这阻碍了建筑物所有者和当地政府官员解决其现有建筑存量中的潜在漏洞。这次研讨会为更好地定义研究计划提供了一条前进的道路，该计划将专注于对这些旧建筑进行更准确的分析和具有成本效益的修复战略的方法。更具成本效益的防塌恢复技术，以及实现更高水平地震安全的技术，将鼓励缓解努力，并在未来的大地震中拯救生命。

The Applied Technology Council (ATC), a non-profit California corporation founded to synthesize and translate structural and earthquake engineering research findings into active engineering practice, will conduct a workshop to identify priorities for research on the seismic vulnerability of existing buildings that could be conducted using the National Science Foundation-funded George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) infrastructure. This workshop will capture the recommendations of practicing structural and geotechnical engineering professionals nationwide and will be co-organized by the Earthquake Engineering Research Institute (EERI), with funding from the Federal Emergency Management Agency (FEMA). FEMA funding will be used to broaden the scope of the workshop to identify key issues related to (1) the short-term implementation and updating of guidance for the seismic rehabilitation of existing buildings, and (2) for the long-term development and enhancement of seismic rehabilitation guidance. This workshop constitutes a major coordinated effort of strategic importance to the National Earthquake Hazards Reduction Program (NEHRP). This workshop also addresses one of the 11 goals for research outlined in the American Competitiveness Initiative: Leading the World in Innovation, Domestic Policy Council, Office of Science and Technology Policy, February 2006: "Advances in materials science and engineering to develop technologies and standards for improving structural performance during hazardous events such as earthquakes and hurricanes (NIST, NSF)." A major product of the workshop will be a workshop findings report that prioritizes needed NEES research efforts on existing buildings. The workshop report will be prepared by an ATC Working Group, a subset of the Workshop Steering Committee. A similar report that focuses on ways to enhance the development and implementation of guidance on the seismic rehabilitation of existing buildings will be prepared, with funding from FEMA, by an EERI Working Group, the other subset of the Workshop Steering Committee.The intellectual merit of this workshop is to establish clear community-based strategic guidance on priorities for NEES research efforts to reduce the seismic vulnerability of existing buildings. Currently available resource documents that identify research needs in earthquake engineering provide only broad guidance on this topic and do not identify specific priorities for research questions that the NEES infrastructure can uniquely address. Much of the nation's existing buildings located in seismically active regions of the United States have yet to be evaluated or strengthened. The lack of fundamental and problem-focused research data has led to significant conservatism in existing evaluation methodologies that discourages building owners and local public officials from addressing potential vulnerabilities in their existing building stock This workshop provides a path forward for a better defined research program that would focus on methods for more accurate analysis of and cost-effective rehabilitation strategies for these older structures. More cost-effective collapse prevention rehabilitation techniques, as well as techniques for achieving higher levels of seismic safety, will encourage mitigation efforts and save lives in future major earthquakes.
