Designing Nonstructural Component Anchorage Using Approximate Floor Response Spectra

Abstract eng:
The seismic behavior of nonstructural components is affected by the interaction of the dynamic behavior of the nonstructural component and the building. Building code requirements for the design of nonstructural components provide approximate procedures for estimating the floor accelerations of a building based on assumptions regarding the dynamic behavior of the building. Since the dynamic behavior of many nonstructural components is not usually well known, building code design methodologies provide only limited consideration of the building’s dynamic characteristics and their effect on the nonstructural component’s dynamic behavior. The interaction between nonstructural components and the building could be determined by the development of floor response spectra, but the effort required to produce floor response spectra are typically not cost effective. A procedure has been developed and recently implemented into the U.S. building codes that allows for an improved consideration of the interaction of nonstructural components and the building. This procedure produces approximate floor response spectra based on an elastic modal analysis of the building. This approximate floor response spectra procedure is described and results are compared to the building code design requirements and the results using floor response spectra generated from response history analyses using several types of nonstructural components for example buildings. Recommendations are made for conditions where the use of the floor response spectra procedures would be beneficial.
