However, with the emergence of advanced repair methods—MMA injection, CFRP wrapping, SMA stitching, and helical screw bridging—this no longer means catastrophic replacement every time. The "new" solutions described here allow for rapid, cost-effective, and durable repairs that often exceed original design capacities.

Cracks in a newly constructed beam often signal a breakdown in the "truss mechanism" intended to carry weight.

Follow manufacturer’s mixing and pressure (30–50 psi maximum to avoid hydrofracing).

When a crack develops near the connection point of an ATIR strap, several issues arise:

: Users can define beams in STRAP and export them directly to BEAMD for 2D analysis and detailing, ensuring that column reactions and support widths are accurately transferred. New in 15.0/2024

| Scenario | Cost per connection (USD) | Downtime | Lifespan extension | |----------|--------------------------|----------|---------------------| | | $1,200 – $4,000 | 2–5 days | 50+ years | | Traditional epoxy + new strap | $300 – $700 | 4–8 hours | 5–10 years | | New method: MMA + CFRP + SMA staples | $600 – $1,200 | 6–12 hours (cure overnight) | 25+ years | | Helical strap bridging only | $150 – $350 | 1–2 hours | 10–15 years |
