Abstract: This paper proposes an approximate derivation for the critical buckling load of a column, based on the application of a uniformly loaded beam's midspan moment and deflection to the buckled column's rotational equilibrium. ...

Abstract: Recommendations for the use of collar beams—horizontal timbers connecting opposing rafter pairs in gable-type wood-frame roofs—are often confusing and contradictory. This is due in large part to their peculiar history: ...

Abstract: Collar beams are used within triangular wooden roof structures as both ridge ties and rafter braces, in spite of the fact that specific recommendations for their use are often contradictory or imprecise. To develop more ...
