A Computer Program for Seismic Analysis of Woodframe Structures
Abstract/Contents
- Abstract
- The main objective of this research project is the formulation and development of a simple numerical model to predict the dynamic characteristics, quasi-static pushover and seismic response of woodframe buildings. 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 the diaphragms and the foundation. The pinched, strength and stiffness degrading hysteretic behavior of each wood shear wall in the building can be characterized using an associated numerical model that predicts the wall’s load-displacement response under general quasi-static cyclic loading. In turn, in this model, the hysteretic behavior of each shear wall is represented by an equivalent nonlinear shear spring element. With this simple approach, the response of the building is defined in terms of only threedegrees- of-freedom per floor. This numerical model has been incorporated into the computer program SAWS: Seismic Analysis of Woodframe Structures. The predictive capabilities of this program are compared with recent shake table tests performed on a full-scale two-story woodframe house.
