Performance-Based Seismic Evaluation of Structural Insulated Panels

Abstract eng:
Structural Insulated Panels (SIPs) represent an example of an energy-efficient structural system. They are composed of an insulation core, such as expanded polystyrene (EPS), with both traditional and novel facing materials such as plywood, oriented strand board (OSB), cement mortar, or steel. Developed over 60 years ago, SIPs are extensively used throughout Europe and North America. However, there is limited information available about the seismic behavior of SIPs. Therefore, their application in seismically hazardous regions is limited due to unacceptable performance as demonstrated by few cyclic tests. Seismic performance of a building constructed from SIPs is evaluated in this study using the performance-based earthquake engineering (PBEE) methodology developed by the Pacific Earthquake Engineering Research (PEER) Center. Several quasi-static and hybrid simulation tests have recently been conducted at University of California, Berkeley to quantify the earthquake response of SIPs. The results of these tests are used in the structural and damage analyses stages of the PEER PBEE methodology. The considered building for this study is a hypothetical two-story single-family house-overgarage building made of SIPs. The building is assumed to be located in San Francisco Bay Area, California, where such buildings are prevalent. Particularly, loss curves are obtained for this building constructed using different nail spacing. From the previously conducted tests, the nail spacing was observed to have considerable effect on the seismic response of SIPs. Results of the PBEE analyses indicated the importance of nail spacing on the seismic performance of a single-family house and highlighted that the usage of SIPs in highly seismic areas can be increased by improving the construction and design details. Increased usage of SIPs is expected to be influential in accelerating the construction process and enhancing the energy-efficiency of the built environment in seismic regions.
