Structural engineering and design has in the past, focused on life safety and the prevention of major structural damage during and earthquake. The Whittier-Narrows earthquake of October 1, 1987, has shown that performance of non-structural items that effect building mission performance to be very important and can have significant effects on economic damage. This research project focuses on seismic design implications/lessons from the extensive non-structural building component damage caused by the Whittier, California Earthquake with emphasis on effects at the CSU-LA campus. The research focuses on the performances and behavior of the interior (e.g., partitions, stair enclosure walls) as well as exterior (e.g., cladding curtain-walls, screen-walls) building components; as well as their influence on the overall seismic behavior of building systems. Available data on damage of interior building components and exterior building components as well as building contents is categorized and analyzed. This includes details of the configuration of buildings, their structural systems, with respect to building components, as well as building component repair cost data. This is followed by selected case-studies of two buildings on the CSU- LA campus that suffered significant non-structural damage in addition to structural damage. The results and conclusions of this research will be more effective methods of deriving lessons from observed damage during severe earthquakes; building component damage during earthquakes; valuable practical data on the performance and behavior of interior non-structural walls and exterior facade/cladding systems; and their influence on the overall response and behavior of building systems during earthquakes.

结构工程和设计过去一直关注生命安全和预防地震期间重大结构损坏。 1987 年 10 月 1 日发生的惠蒂尔海峡地震表明，影响建筑任务性能的非结构性项目的性能非常重要，并且可能对经济损失产生重大影响。 该研究项目的重点是加利福尼亚州惠蒂尔地震造成的广泛非结构建筑构件损坏的抗震设计影响/教训，重点是对科罗拉多州立大学洛杉矶校区的影响。 研究重点是内部（例如隔断、楼梯围墙）以及外部（例如覆层幕墙、影壁）建筑构件的性能和行为；以及它们对建筑系统整体抗震性能的影响。 对内部建筑构件和外部建筑构件以及建筑内容的损坏的现有数据进行分类和分析。 这包括建筑物配置、结构系统、建筑组件的详细信息，以及建筑组件维修成本数据。 随后对科罗拉多州立大学洛杉矶分校校园内的两座建筑进行了选定的案例研究，这些建筑除了结构性损坏外，还遭受了严重的非结构性损坏。 本研究的结果和结论将成为更有效的从严重地震震害观测中汲取教训的方法；地震期间建筑构件损坏； 有关内部非结构墙和外部立面/覆层系统的性能和行为的宝贵实用数据；及其对地震期间建筑系统整体响应和行为的影响。
