Abstract
The objective of this study was to compare structural load path and system behavior of a light-frame (LF) and a timber frame (TF) structure. This load path analysis is part of a broader research effort that compares LF to TF residential structures. Structural analysis software was used to create a model of each structure. The TF structure was composed of large-dimension timbers and structural insulated panels (SIPs). An equivalent LF structure was designed for comparison, following the guidelines of the International Residential Code. Results show that TF outperforms LF in resisting uplift, as well as in story drift. TF also provides load paths that are more resistant to the introduction of large openings and the loss of a central post. Observed axial loads in TF posts show smaller ranges compared with LF studs.
