ABSTRACT

The main objectives of the research project reported herein are to identify gaps in knowledge regarding the seismic behavior of nonstructural building components and to help develop a research strategy within the Pacific Earthquake Engineering Research (PEER) on nonstructural building components.

For this purpose, existing guidelines and regulations for the design and testing (qualification) of nonstructural components were compared, and published analytical and experimental research on nonstructural components was reviewed.

Chapter 1 presents an introduction to this project along with a general discussion on the need to address the seismic behavior of nonstructural building components. In Chapter 2, the performance of nonstructural building components during the recent February 28, 2001, Nisqually, Washington, earthquake is reviewed. The performance of nonstructural components during other earthquakes in the United States is reviewed in Chapter 3. In Chapter 4, an inventory and comparison of existing regulations and guidelines for the seismic design and specification of nonstructural building components are presented. Past analytical and experimental investigations on the seismic response of nonstructural building components are briefly reviewed in Chapter 5. The computerized database that has been developed in this project to centralize this large amount of information, as well as to facilitate any future literature searches on the seismic behavior of nonstructural building components, is briefly described in Chapter 6. Chapter 7 provides a summary of gaps in knowledge and recommendations for the development of a rational research plan on nonstructural building components.
