Material Properties

Concrete (for slabs, beams, and columns):

• Unit weight, w
• Compressive strength, f'c
• Modulus of elasticity, Ec
• Modulus of rupture, fr

Steel:

Structure Geometry

• Up to 20 spans
• May include two cantilevers
• Slab thickness may vary from span to span
• Transverse design strip width (left and right) may vary from span to span
• Round or rectangular columns above and below the slab
• Column height may vary
• User-controlled column-fixity
