Atir Strap And Beamd With Fix | Crack Link
Introduction
Problem: A 450 mm × 300 mm RCC beam showed a 2.5 mm wide vertical flexural crack at mid-span, extending 80% of beam depth. Atir Strap And Beamd With Fix Crack
5. Typical Applications
- Slab cracks: ATIR straps installed in tension zones of slabs (e.g., near midspan or over supports).
- Wall cracks: Horizontal or diagonal straps to resist out-of-plane bending or in-plane shear.
- Beam flexural cracks: ATIR beam applied along the tension face to add reinforcement.
- Joints between precast elements: ATIR beam used as a concealed tie.
- Seismic retrofitting: Cracked shear walls repaired with crossing straps.
4. Live Crack Closure Feedback
- Uses digital image correlation (DIC) or displacement sensors.
- During tensioning of the ATIR strap, user sees crack width reduction in real time.
- Alerts if uneven closure or new micro-cracks appear.
Always consult a structural engineer for final design. Introduction Problem: A 450 mm × 300 mm
