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

过去，结构工程和设计的重点是生命安全和防止地震期间的重大结构破坏。1987年10月1日的惠蒂埃-纳罗斯地震表明，影响建筑任务性能的非结构项目的性能非常重要，可能会对经济损失产生重大影响。这项研究项目集中于加州惠蒂尔地震造成的广泛的非结构建筑构件破坏对抗震设计的影响/教训，重点是对CSU-LA校园的影响。研究的重点是内部(如隔断、楼梯围护墙)和外部(如覆层幕墙、幕墙)建筑构件的性能和行为，以及它们对建筑体系整体抗震性能的影响。对室内建筑构件和外部建筑构件的损伤以及建筑内容的现有数据进行了分类和分析。这包括关于建筑构件的建筑物配置及其结构系统的详细信息，以及建筑构件维修费用数据。随后是对CSU-LA校园中的两栋建筑的选定案例研究，这两座建筑除了结构损坏外，还遭受了严重的非结构损坏。这项研究的结果和结论将是从严重地震期间观测到的破坏中吸取教训的更有效的方法；地震中建筑构件的破坏；关于内部非结构墙和外部立面/覆层系统的性能和行为的有价值的实用数据；以及它们对建筑系统在地震中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.
