A simple structural analysis model to predict the seismic response of woodframe buildings is presented. In this model the building structure is composed of two primary components: rigid horizontal diaphragms and nonlinear lateral load resisting shear wall elements. The actual three-dimensional building is degenerated into a two-dimensional planar model using zero-height shear wall spring elements connected between adjacent diaphragms or the foundation. The hysteretic behavior of each wood shear wall in the building can be characterized using an associated numerical model that predicts the walls load-displacement response under general quasi-static cyclic loading. With this simple structural model the response of the building is defined in terms of only three-degrees-of-freedom per floor. This numerical model has been incorporated into the computer program SAWS - Seismic Analysis of Woodframe Structures. The predictive capabilities of the SAWS model are compared with recent shake table tests performed on a full-scale two-story wood frame house under the CUREECaltech Woodframe Project.
Dr. Bryan Folz received his Ph.D. in Civil Engineering from the University of British Columbia in 1988. Since then he has been a Faculty and Head in the Department of Civil Engineering at the British Columbia Institute of Technology where he teaches in the area of Structural Engineering. From 2000 to 2001, Dr. Folz was a Visiting Associate Professor in the Department of Structural Engineering at the University of California in San Diego, where he conducted research on the seismic response of wood buildings within the FEMA-funded CUREE-Caltech Woodframe Project.
