• Finite element analysis of first curved truss showed huge shears at base and excessive moments in curvesfinding0.788
  First step of finite element analysis on a curved tracery truss revealed bad structural behavior.
• The floral plant-like truss that emerged was a completely new structural configuration, a previously unknown tension network arch.claim0.760
  Claim about the structural innovation achieved through the unfolding process.
• Scissors truss tension straight member carried almost no tension; major tension went around arch itselffinding0.754
  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 capacityfinding0.737
  The efficient triangulated model showed excellent structural behavior.
• Thick version of scissors truss became squat and ugly when members were widened to 6-9 inchesfinding0.734
  Aesthetic failure when moving from theoretical lines to real dimensions.
• Lily configuration reduced shear to 5,000 lbs but caused bending moment of 114,000 inch lbs at peakfinding0.725
  Aesthetic improvement solved shear but introduced high bending.
• 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.finding0.721
  Empirical finding from full-scale on-site testing: the correct proportions for intimacy were discovered through experiment, not calculation.
• Stress sharing benefit scales with grid complexity (20x20, 30x30, 50x50) and becomes more pronounced in later evolutionary stages when mutations alone failfinding0.720
