Intended users

  • architecture and structural engineering students
  • architects and early-phase structural designers exploring forms like shear walls, cantilevers, and tall slender elements
  • designers needing rule-of-thumb validation before detailed modeling or analysis

Need you’re trying to provide a solution or support for

  • early design phases often involve creative geometry without engineering checks, or if it includes engineering checks it takes significantly longer
  • designers need quick feedback on whether structural elements are proportionally viable
  • early feedback helps avoid rework and encourages more efficient and transparent collaboration between architects and engineers

Inputs

  • geometry: member type (column, wall, truss, plate, arch, cantilever, etc)
  • dimensions: height, width, depth, span
  • support condition: simply supported or cantilevered

Underlying logic of the model you’ll implement

  • uses common structural heuristics to evaluate aspect ratio feasibility
    • axial (columns): max 50:1 slenderness
    • bending (beams, arches): max 20:1 span-to-depth
    • shear (plates, walls): max 1:2 height-to-width
    • torsion (thin shafts): max ~6.28:1 (2π:1)
    • pure tension: idealized to infinity but limited in practice by constructability
  • for cantilevers, applies half of the aspect ratio limits used for simply supported members
  • provides feedback when input dimensions exceed safe or typical structural behavior limits
  • suggests more appropriate structural strategies based on geometry and behavior

Outputs

  • pass/warning/fail based on calculated aspect ratio
  • recommended structural system or member type (switch to truss, increase depth, brace column, etc)
  • visual cue or color-coded status indicator (mayhaps)
