System Stability in Wood Truss Assemblies during Construction

Feature

Euler’s buckling formula dates back to 1757; we still use it today to determine bracing.
With the creation of an analysis program that more accurately predicts the behavior of a truss system, bracing designs can be examined.
Given that relatively few material properties were measured, the SAWFT predictions are surprisingly close to the instability loads obtained from the tests.
This work shows promise as a first step toward development of robust structural analysis algorithms for developing new design procedures for wood structural system stability.
