A 450 mm × 300 mm RCC beam showed a 2.5 mm wide vertical flexural crack at mid-span, extending 80% of beam depth.
Select a 50 mm × 5 mm strap (area = 250 mm²) → acceptable. Atir Strap And Beamd With Fix Crack
[ A_s = \frac15 \times 10^60.87 \times 250 \times 300 = 230 \text mm^2 ] A 450 mm × 300 mm RCC beam showed a 2
For building owners, contractors, and engineers facing a cracked beam, this technique offers a middle ground between cosmetic patching and expensive replacement. When executed with proper materials, correct anchor detailing, and monitored post-installation, an Atir strap can extend a building’s service life by decades.

Introduction In the world of civil engineering and structural rehabilitation, few sights are as alarming as a cracked RCC (Reinforced Cement Concrete) beam. Whether in a residential building, a commercial complex, or an industrial warehouse, beam cracks compromise load-bearing capacity and safety. Among the most effective, economical, and widely adopted repair methodologies in South Asia and the Middle East is the use of the Atir Strap —a steel tension strapping system designed to arrest crack propagation and restore structural integrity.
