: Display the cracked shape and values graphically to compare against linear elastic results.

Concrete shrinks as it cures, and thermal expansion/contraction can cause significant cracking.

(transverse reinforcement) are insufficient or the shear capacity has been exceeded. Flexural Cracks

Think of STRAP as the "brain" of the operation. It's where engineers build the digital skeleton of their projects—from towering skyscrapers and expansive bridges to intricate communication towers and industrial tanks. The software's primary function is to predict how these structures will behave under various conditions, such as heavy wind loads, seismic activity, or the simple weight of materials and occupancy.

High. Requires immediate structural reassessment. 4. Non-Structural Cracks (Plastic Shrinkage & Settlement)

: A specialized, fully integrated module focused entirely on reinforced concrete (RC) beam design, detailing, drafting, and scheduling. It automates the tedious engineering task of generating reinforcement layouts and bending schedules. New Capabilities in the Latest Versions

When installed correctly, the repaired beam behaves like a — hence the keyword phrase “beam with crack new” meaning: the beam is treated as new after strap installation.

The atir straps are coated with a structural epoxy matrix. They are then wrapped tightly around both the original concrete beam and the newly installed supplementary beam. Specialized tensioning jacks tighten the straps to a precise specification, compressing the newly sealed crack. Step 5: Curing and Protective Coating

: Top-expanding submenus standardize navigation across all modules.

Analytically, an edge crack is often modeled as a rotational spring connecting two beam segments at the crack location. When the bending moment changes sign, the crack may “breathe”—opening during tension and closing during compression. In the compression zone, a crack can be forced shut, causing the beam to behave like an intact solid. This breathing behavior introduces nonlinearity and is a focus of advanced research.

STRAP can be used to analyze the repaired beam, verify that the restored section meets serviceability limits, and generate updated details. BEAMD then produces the reinforcement or patching schedule, ensuring the repair is accurately documented.

: These typically occur near support points at a 45-degree angle. They suggest that the stirrups are either under-designed or improperly spaced.
