Flexural design of concrete beams, slabs, and walls

Design Elevated Slabs and Environmental Walls

Engineers Stand on ConcreteBending

ConcreteBending helps you model concrete bending problems using high-level components and engineering terminology. The tool automatically constructs an accurate Finite Element Model.

Concrete Flexure

Model slab, beam, or wall bending problems quickly.
  • Complex perimeters
  • Multiple slab thicknesses
  • Holes in the slab
  • Beams or column supports

Rapid Loading

Apply point, line, or area loads easily.
  • Organize loads by service cases
  • Automated building code combinations
  • Copy and paste abilities

FEA Power

Automatic finite element meshing and analysis.
  • Graphical views of results
  • Statics checking
  • Error prevention logic
  • Command-line and scripting support

Smart Design

ACI 318, CSA A23.3 and ACI 350 specifications.
  • You stay in control of design
  • Specify your rebar patterns
  • Program can choose rebar

Punching Shear

Punching boundaries around columns or walls are determined for you.
  • d/2 distance from face
  • Overlapped boundaries checked
  • Override punching boundary

Beam Checks

All beam limit states are checked. Rebar and details are provided.
  • Shear, moment and torsion checks
  • Rebar patterns shown graphically
  • Intermediate values reported
