Performance and Behavior of Non-Structural Components in Instrumented Buildings Including Their Contribution to the Overall Earthquake Resistance:Inter-Story Drift Behavior...

研究了1994年1月17日北岭地震中仪器仪表建筑非结构构件的性能和行为。重点放在抗震设计的意义/经验教训上。分析了拟研究的建筑内外构件对建筑体系整体抗震性能的影响。本文还研究了非结构墙体构件对建筑体系整体抗震性能的贡献，以及它们对层间漂移行为的影响。所有关于内部和外部建筑构件（包括货架和内容物）损坏的可用数据都将被筛选、分类和分析。还将研究关于非结构建筑部件的修理和改造费用的现有数据。将对两座建筑物进行个案研究，这些建筑物除了结构损坏外，还遭受了重大的非结构损坏。第一个是一个七层的酒店建筑，它不仅遭受了严重的结构性破坏，而且遭受了严重的非结构性破坏。第二个案例研究将是钢框架建筑的包层和连接，特别是抗力矩框架。本研究的结果和最终产品将提高对非结构构件对建筑系统整体抗震性能的贡献的理解。获得的定量结果将有助于改进非结构部件的抗震设计标准，包括其维修和改造的指导方针。这是北岭地震项目。* * *

9416524 Rihal The performance and behavior of non-structural components in instrumented buildings during the Northridge earthquake of January 17, 1994 is investigated. The focus is placed on the seismic design implictions/lessons learned. The proposed research on the influence of the interior as well as exterior building components on the overall seismic behavior of building systems is analyzed. Included is also an investigation of the contribution of non-structural wall components to the overall earthquake resistance of building systems as well as their influence on the inter-story drift behavior. All available data on damage of interior as well as exterior building components, including shelving and contents, will be screened, categorized and analyzed. Available data on the costs of repair and retrofit of non-structural building components will also be studied. Case-studies of two buildings that suffered significant non-structural damage in addition to structural damage will be constructed. The first one is a instrumentedd seven story hotel building suffered not only severe structural damage but also significant non-structural damage. A second case- study will be cladding and connections in steel framed buildings, especially with moment-resisting frames. The results and final products of this research will be improved understanding of the contribution of non-structural component to the overall earthquake resistance of building systems. The quantitative results obtained will help develop improved seismic design criteria for non-structural components including guidelines for their repair and retrofit. This is a Northridge earthquake project. ***
