After you perform the Atir strap and beamd with fix crack repair, inspect the repair every 6 months:
If you see new cracks forming next to the strap, the beam has failed globally, and you need a full replacement.
Yes, unless covered by false ceiling or plaster. It can be painted to match surroundings.
The ATIR Strap and Beam with Fix Crack method offers a robust, durable, and structurally sound solution for repairing active cracks in concrete. It goes beyond cosmetic sealing by mechanically restoring tensile continuity and preventing future cracking. While more invasive and costly than surface treatments, it is superior for structural-grade repairs where crack recurrence would be critical. For engineers seeking a permanent fix, especially in seismic zones or heavily loaded structures, ATIR systems are a highly recommended alternative to conventional composite wraps or injection-only approaches.
Recommendation: Use ATIR strap for planar cracks (slabs/walls) and ATIR beam for linear cracks (beams/edges). Always pair with proper surface preparation and corrosion protection. Further field data on long-term moisture and chemical resistance would strengthen its adoption.
Introduction
Atir Strap and Beamd are two popular software solutions used in the construction industry for designing and detailing reinforced concrete structures. While they are widely used, some users may encounter issues with cracks in their designs. In this feature, we'll explore the concept of Atir Strap and Beamd, their benefits, and provide a fix for cracks. Atir Strap And Beamd With Fix Crack
What is Atir Strap?
Atir Strap is a software solution used for designing and detailing reinforced concrete slabs, beams, and foundations. It allows users to create detailed designs and calculations for reinforced concrete structures, taking into account various factors such as loads, materials, and codes.
What is Beamd?
Beamd is a software solution used for designing and detailing reinforced concrete beams and columns. It provides users with a comprehensive toolset for creating detailed designs and calculations for reinforced concrete beams and columns, including analysis and verification of beam and column designs.
Common Issues: Cracks in Designs
One common issue users may encounter when using Atir Strap and Beamd is the appearance of cracks in their designs. Cracks can occur due to various factors, including: After you perform the Atir strap and beamd

Engineers must verify that the Atir strap can resist the tensile force that caused the crack. A basic approach:
Required strap area: [ A_s = \fracM0.87 \times f_y \times d ] Where:
Example: For a cracked beam with moment demand of 15 kN·m, using ( f_y = 250 \text MPa ), and strap depth ( d = 300 \text mm ):
[ A_s = \frac15 \times 10^60.87 \times 250 \times 300 = 230 \text mm^2 ]
Select a 50 mm × 5 mm strap (area = 250 mm²) → acceptable.
Always consult a structural engineer for final design.
Before understanding the fix, one must understand the failure. Masonry walls (brick, block, or stone) are strong under compression (weight pushing down) but weak under tension (pulling apart). When the ground shifts, foundations settle, or thermal expansion occurs, the wall is subjected to tension. It responds by cracking.
Once a crack forms, the masonry on either side loses its connection. The building becomes a collection of separate parts rather than a unified structure. The goal of the "Strap and Beam" method is to stitch those parts back together.
