Design¶
Design
Three modules take material laws, fitted or assumed, and compute the response of a member: moment-curvature with its limit states, load-deflection, stress and force profiles, and for the cross-sectional module the P-M interaction diagram.
Closed form · rectangular
Hybrid beam analysis
FRC or UHPC matrix with top and bottom rebar. Fourteen stages, limit states, load-deflection with localization.
Closed form · rectangular
FRP rebar and strengthening
Non-metallic bars and an externally bonded FRP laminate.
Iterative · any shape
Cross-sectional analysis
Presets or drawn polygons, rebar layers, prestressing tendons, limit states and the P-M diagram.
The sequence¶
| Step | Input tab or button | What you do |
|---|---|---|
| 1 | Geometry or Section | Span, section, cover, bars, loading, plastic length |
| 2 | Import Material or the material tabs | Bring in a fitted law from an inverse-analysis workbook, or type one |
| 3 | Reinforcement, FRP Laminate, Tendons | Reinforcement laws and layout |
| 4 | Update Results or Run Analysis | Compute |
| 5 | Result tabs | Read the limit states, the load-deflection curve, the profiles |
| 6 | Export Report, Download Output Data, Save | Keep the analysis |
The material laws and their normalized parameters are described under Material models and notation. The fourteen stages of the hybrid section are described under Closed-form moment-curvature.
