Greater than 3mm wide; 45-degree angle near the beam supports. (Critical) Severe structural overloading; foundation movement. Spalling & Rust Stains

Cracks in ATIR-modeled beams typically fall into three categories: Vertical cracks at the bottom of the beam. Shear Cracks: Diagonal cracks near the supports. atir strap and beamd with crack

This is a comprehensive guide addressing the causes, implications, and repair strategies for cracks in strap beams, often referred to as ATIR strap beams or simply strap beams/strap footings. Understanding and Repairing Cracks in Strap Beams (ATIR) Greater than 3mm wide; 45-degree angle near the

A cracked strap or beam in a structural assembly can compromise load transfer and safety. This article explains how to identify cracks, assess severity, select repair methods, perform repairs, and prevent recurrence. It applies to common materials (steel, timber, and reinforced concrete) and typical strap/beam connections (bolted, welded, nailed, or adhesive). Shear Cracks: Diagonal cracks near the supports

For the most demanding applications—such as beams with large openings or unusual reinforcement configurations—engineers may complement the STRAP + BEAMD workflow with specialized detailing software such as IDEA StatiCa to perform detailed crack width checks and stress concentration analyses.

If the crack is widening rapidly, immediately install temporary screwjack posts under the beam to relieve the load.
