Perfect Structure - RC Design

Design and check reinforced concrete columns and beams on your phone or tablet. Enter the section, loads and material grades, press Calculate, and get a clear results screen with a code-compliance check in seconds. Export the calculation report as PDF, CSV or DXF and share it with colleagues.

Key features:
- 5 design codes: ACI 318, Eurocode 2, BS 8110, SP 63.13330 and TS 500
- 8 languages: English, German, French, Italian, Spanish, Portuguese, Russian and Turkish
- Metric (SI) units, plus Imperial units under ACI 318
- Column sections: rectangular, circular, hollow rectangular and hollow circular
- Beam sections: rectangular, T-beam, I-beam and box beam (hollow core)
- Singly and doubly reinforced beams
- Column interaction diagrams
- Two modes: check a given reinforcement against the loads, or calculate the optimal reinforcement
- Flexural and shear reinforcement, designed and checked
- Output as PDF, CSV or DXF section drawing

How it works: choose column or beam on the main screen, select the section type, enter dimensions, loads, and steel and concrete grades, then press Calculate. The results screen shows the reinforcement, the capacity checks and how the design complies with the selected code. Try different bar arrangements and member dimensions to reach the optimal configuration. The settings page covers design code selection, units, language and feedback.
