Load Paths in Light-Frame Wood House with Complex Geometry
Publication: Journal of Architectural Engineering
Volume 27, Issue 2
Abstract
The objective of this study was to investigate load paths in an existing light-frame wood structure with a complex, realistic geometry using computer modeling methods developed by the authors for simpler structures. The structural model was derived from an existing, multilevel residence located in Corvallis, Oregon. Gravity and wind loads were examined. Modeling was done with SAP 2000 for behavior within the linear-elastic range using frame and shell elements. Results showed gravity load paths and the governing load combinations for different parts of the structure. Wind investigations revealed load concentrations at corners and openings due to uplift pressure on the roof and overturning forces from lateral wind loads on the walls. Additionally, load concentrations are dependent on wind direction and loading type and the dead load present. Load paths for this asymmetrical structure show that the shear carried in each wall is dependent on the wind direction and wall stiffness.
