Single Gusset Support Lugs
Single Gusset Support Lugs
(OP)
Compress provides calculations for support lugs with double gussets.
Are there any plans to add the capability to analyse support lugs with single gussets?

RE: Single Gusset Support Lugs
Briefly, COMPRESS determines the thickness of the base plate by treating it as a rectangular plate supported on 3 sides, the fourth edge is 'free'. The load is appplied as a uniformly distributed load. The rules of Timoshenko's "Theory of Plates and Shells" are applied (see "Formulas for Stress and Strain" by Roark) to find the maximum stress, which is set equal to the allowable stress to determine the required thickness.
A similar approach would be followed for the case of the single gusset. The solution is more complex though due to the support (edge) conditions. If we're all lucky, there is a solution (to the differential equation) already available in Timoshenko or Roark. If not, well...
Note that COMPRESS will currently design support lugs without the top plate by simply entering "0" for the width of the top plate.
