Thick version of scissors truss became squat and ugly when members were widened to 6-9 inches

Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• Scissors truss tension straight member carried almost no tension; major tension went around arch itselffinding0.781
  Detailed review of forces disproved the initial assumption that a straight tension tie was essential.
• Perfectly triangulated scissors truss had low bending moments and shears, all within capacityfinding0.762
  The efficient triangulated model showed excellent structural behavior.
• First plant-like truss: shear force of 7,400 lbs in top chord near peak (exceeding 3,344 lbs capacity); high shears in arch (4-8,000 lbs); high shear in edge member (8,000 lbs)finding0.734
  Finite element analysis identified three critical shear problem areas in the first beautiful design.
• When you use nicely shaped triangles, the triangles naturally get smaller where the area of the truss gets tighter, corresponding to the zone with the biggest flow of forces.claim0.729
  Observation about the cooperation between geometric features and structural features.
• At West Dean, the columns that felt best in full-scale cardboard experiments had capitals at head height (c. 1.70m), rising to c. 2.10m at arch midpoint — far lower than initially expected.finding0.718
  Empirical finding from full-scale on-site testing: the correct proportions for intimacy were discovered through experiment, not calculation.
• Lily configuration reduced shear to 5,000 lbs but caused bending moment of 114,000 inch lbs at peakfinding0.712
  Aesthetic improvement solved shear but introduced high bending.
• Finite element analysis of first curved truss showed huge shears at base and excessive moments in curvesfinding0.708
  First step of finite element analysis on a curved tracery truss revealed bad structural behavior.
• The very same positive space which creates a truss's beauty also creates its structural stability and good structural behavior.claim0.692
  Direct connection between aesthetic quality and engineering performance.
