A Theory for Struts with Lattice or Batten Bracing

Summary In this paper, it is assumed that the shear stiffness of a panel can be taken as distributed uniformly along the strut. "Secant" type formula (I), (2), (3) and (4) provide the crippling load of a strut with light shear bracing for the simpler case of equal eccentricities of end load; formulae (I), (4), (5) and (6) deal with the more general case of different end eccentricities and a uniform transverse loading. These formulae differ from those for a strut with heavy shear bracing only in an extra term incorporating the shear stiffness. Expressions for shear stiffness of the usual forms of light shear bracing, such as lattice bracing, with and without posts, and batten bracing with equal and unequal chords, are given by formulae (7) to (12).
