In ATIR STRAP, managing reinforced concrete beams and addressing crack control is a core part of the design and detailing workflow. The software uses a modular approach, where the main STRAP finite element analysis results are passed to the RC Beams (often referred to in detailing contexts as BEAMD) post-processor to finalize reinforcement and check for serviceability requirements like crack widths. RC Beam Design and Crack Control Workflow
The straps are saturated with resin and bonded perpendicular to the crack. Once cured, these straps are often stronger than the original steel reinforcement inside the concrete. Why This Method? Atir Strap And Beamd With Fix Crack
Features of Atir Strap And Beam:
| Mistake | Consequence | Solution | |---------|-------------|----------| | Drilling into rebar | Severed tension steel, worse than original crack | Use rebar locator before drilling | | No crack injection | Internal void remains, corrosion continues | Inject epoxy before strapping | | Overtightening bolts | Concrete spalling around anchor | Use torque wrench + embed plate if needed | | Using untreated mild steel | Rust expansion re-cracks beam within months | Use galvanized or epoxy-coated straps | | Single strap for shear crack | Insufficient resistance – diagonal failure repeats | Apply crisscross straps (X-pattern) | In ATIR STRAP , managing reinforced concrete beams
