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）是一家非营利性的加州公司，旨在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，它将举办一个研讨会，以确定现有建筑物地震易损性研究的优先事项，这些研究可以使用国家科学基金会资助的乔治E.小布朗地震工程模拟网络（NEES）基础设施。 该研讨会将收集全国范围内执业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）共同组织，由联邦应急管理局（FEMA）提供资金。 联邦应急管理局的资金将用于扩大研讨会的范围，以确定与以下方面有关的关键问题：（1）现有建筑物抗震修复指南的短期实施和更新，以及（2）抗震修复指南的长期发展和加强。 这次研讨会是对国家减少地震灾害计划（NEHRP）具有战略重要性的主要协调努力。 该讲习班还讨论了美国竞争力倡议中概述的11个研究目标之一：在创新方面领导世界，国内政策理事会，科学和技术政策办公室，2006年2月： “材料科学和工程的进步，以开发技术和标准，以改善地震和飓风等危险事件期间的结构性能（NIST，NSF）。“研讨会的一个主要成果将是一个研讨会的调查结果报告，优先考虑现有建筑物所需的NEES研究工作。 研讨会报告将由ATC工作组（研讨会指导委员会的一个分支机构）编写。在FEMA的资助下，研讨会指导委员会的另一个子集EERI工作组将编写一份类似的报告，重点关注如何加强现有建筑地震修复指南的制定和实施。本次研讨会的智力价值是为NEES研究工作的优先事项建立明确的基于社区的战略指导，以减少现有建筑的地震脆弱性。目前可用的资源文件，确定在地震工程的研究需求，提供了广泛的指导，这一主题，并没有确定具体的优先级的研究问题，NEES基础设施可以唯一解决。 位于美国地震活跃地区的许多国家现有建筑物尚未进行评估或加固。由于缺乏基本的和以问题为重点的研究数据，导致现有评估方法过于保守，不鼓励建筑物所有者和地方政府官员解决现有建筑物中的潜在脆弱性 本次研讨会提供了一个更好的研究计划，将重点放在更准确的分析和成本效益的康复策略，这些老结构的方法前进的道路。 更具成本效益的倒塌预防修复技术以及实现更高地震安全水平的技术将鼓励减灾努力，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.
