The A-Beam+ is the extension of the previous A-Beam app that make the design of the RC beam easy and as simple as using the normal calculator. But behind the simplicity the app also provide the very details of the calculation in every step to make you confident with the calculation result. The initial version support for the "ACI 318" Building Code both US & Metric (SI-Metric and MKS-Metric) units with more other design codes will be added.
Rectangular Beam
This app assists in the design and analysis of reinforced concrete rectangular beams. It calculates required reinforcement, draws beam sections with rebar details, and provides strain distribution diagrams. Users can also determine crack width and deflection, and generate PDF reports.
- Reinforcement calculation
- Beam section drawing
- Layer requirement check
- Strain distribution diagram
- Crack width calculation
- Deflection calculation
- PDF report generation
