Stability analysis of truss chords loaded by a
combination of axial and lateral forces is studied. A
simple model based on beam-column theory is proposed and
analyzed. The continuous truss chord is replaced by a beam column
loaded by end moments replacing the effect of
adjacent members. The solution yields deflections and
moments allowing one to compute the stress at any point of
the truss chord. Analytical and numerical solutions are
applied to an example of a wood truss with a continuous top
chord. The numerical solution for the deformations
converges rapidly. Non-converging results indicate
instability.
A new design procedure for wood truss chords subjected
to possible buckling is proposed. The procedure is based on
the analysis of a beam-column model and a mechanics of
materials approach. / Graduation date: 1994
