Modeling Wood Walls Subjected to Combined Transverse and Axial Loads
Publication: Journal of Structural Engineering
Volume 131, Issue 5
Abstract
Repetitive-member wall systems are among the most essential structural systems in conventional light-frame construction. Wood stud walls serve a variety of structural functions, particularly in regions of high natural-hazard risk, carrying axial forces, in-plane shear forces, and out-of-plane forces. This paper describes a structural analysis model for wood walls under transverse wind loads combined with either axial tension from wind uplift or axial compression from snow and live load suitable for reliability studies. The average model results compared well to available wall test data. Monte Carlo simulation was used in sensitivity studies of the transverse ramp-load behavior of walls under various levels of axial load. These simulations show that the model captures the range of possible behaviors of stud walls under various levels of axial load, both compression and tension. The model is accurate and simple enough to be used in reliability analyses, which will be described in a later paper.
