Old-school epoxy is rigid. When a beam cracks near a strap, some flexibility is needed to absorb micro-movements.
Diagonal cracks, often at a 45-degree angle, typically indicate shear failure, where the beam's concrete fails diagonally under load. The Role of Modern Materials and Techniques
Typically found at the bottom of the beam's mid-span, these are caused by excessive bending.
Immediately stop repair and replace the beam if:
: Monitor the area and seal it to prevent moisture intrusion. Linear Structural Cracks (Medium Risk) Size : 1 to 3 millimeters wide. atir strap and beamd with crack new
ATIR STRAP (STRuctural Analysis Program) is a Windows‑based suite of finite element analysis and design tools developed by ATIR Engineering Software Ltd., a company founded in 1983 with the motto “Simplicity is a prerequisite for reliability” . Today, the software is used by thousands of engineering firms, government agencies, and academic institutions worldwide.
Horizontal structural members that carry vertical loads from slabs and transfer them to columns.
A crack in a new beam is particularly alarming because it suggests a failure in design, material quality, or curing process. If left untreated, this crack can propagate under service loads, reduce shear capacity, and allow moisture ingress, leading to corrosion of internal rebar. Traditional repair methods (e.g., epoxy injection) restore monolithic action but do not increase the beam’s original strength or ductility.
: STRAP allows for multi-story staged construction analysis. This is critical for new buildings, as construction loads applied floor-by-floor can differ significantly from final design loads. BeamD Integration : For detailed 2D analysis, models are exported to to specify bar diameters, curtailments, and cover details. 3. Crack Analysis Features Old-school epoxy is rigid
The reality is clear. ATIR STRAP and BEAMD are exceptional, world-class tools used by thousands of engineering firms globally for projects ranging from simple homes to complex skyscrapers. The integration between STRAP's powerful analysis and BEAMD's specialized detailing provides a smooth, efficient workflow that is the dream of any structural design team.
These two components work in tandem to manage different types of stress within a concrete or steel structure.
These features make the “new” combination a powerful, up‑to‑date toolkit for structural engineers.
This technical guide explores the engineering principles, installation procedures, and structural benefits of using atir strap and beam reinforcement on newly cracked concrete infrastructure. Understanding the Mechanics of Structural Cracking The Role of Modern Materials and Techniques Typically
A key advantage is BEAMD’s international versatility. For the United States, it produces beam schedules in the American format; for Europe and other regions, it delivers full reinforcement details including cross‑sections and bar schedules. Users can output single beams per sheet or combine multiple beams on a full‑size drawing, all without requiring a separate CAD system.

The supplementary support beam is aligned parallel to the stress zone. Heavy-duty mechanical or chemical anchors secure this beam into the uncompromised, solid sections of the original concrete structure. Step 4: Wrapping and Tensioning the Atir Straps
