Behavior of Architectural (Non-Structural) Building Components at CSU, LA Campus During the Whittier Narrows, California, Earthquake of October 1, 1987 - etc.

在过去，结构工程和设计的重点是生命安全和防止结构在地震中遭受重大破坏。1987年10月1日的惠蒂尔-纳罗斯地震表明，影响建筑任务性能的非结构性项目的性能非常重要，对经济损失有重大影响。本研究项目侧重于加利福尼亚惠蒂尔地震造成的大量非结构性建筑构件损坏的地震设计启示/教训，重点是加州大学洛杉矶分校校园的影响。研究的重点是内部（例如，隔板，楼梯围墙）以及外部（例如，包层幕墙，屏风墙）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。对现有的建筑内部构件和外部构件以及建筑内容物的损坏数据进行了分类和分析。这包括建筑物配置的细节，它们的结构系统，相对于建筑构件，以及建筑构件维修成本数据。接下来是对CSU- LA校区的两座建筑的案例研究，这些建筑除了遭受结构性破坏外，还遭受了严重的非结构性破坏。本研究的结果和结论将是从强震中观测到的破坏中吸取教训的更有效的方法；地震时建筑物构件的损坏；关于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；以及它们对地震期间建筑系统的整体反应和行为的影响。

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.
