Evaluate the beam you entered.
One proposed design is calculated at a time.
Reinforced-concrete design exploration
Discover the beam you need.
Beam Catalog searches predefined, versioned SI and US beam combinations. Filter geometry, material strengths, reinforcement, and moment demand; compare capacity; then share or print an exact result.
2.7 million SI combinations · 1.4 million US combinations
A catalog, not only a calculator
Discover the beam you need.
Search a validated design space and compare available alternatives.
Built for selection and communication
Engineering filters
Search by section dimensions, concrete and steel strengths, bar sizes, bar counts, and required Mu.
Capacity context
Review φMn, φVn, reinforcement ratio, effective depth, neutral-axis ratio, and beam classification.
Canonical beams
Every exact catalog result has a reproducible address suitable for sharing and technical discussion.
Practical output
Create structured JSON or portrait A4 beam sheets with reinforcement sketches and the derived s–φVn schedule.
Standard catalog or custom geometry
Use V2 to explore cataloged beam combinations. When a project needs an unusual dimension such as b = 305 mm or h = 621 mm, Legacy V1 remains available for custom generation.
