The ATIR STRAP and BEAMD integration offers structural engineers a robust, code‑compliant solution for concrete beam design with comprehensive crack analysis capabilities. From initial finite element modeling to final reinforcement detailing, the workflow automates the tedious aspects of crack width verification while giving engineers full control over design decisions. By understanding the fundamental causes of cracking in concrete beams and leveraging the advanced serviceability checks built into BEAMD, engineers can produce safe, durable, and economical beam designs that meet the most demanding international standards. By understanding the fundamental causes of cracking in
: The module checks if the design complies with specific codes (like Eurocode 2 or IS 456). For instance, standard codes often limit crack widths to 0.3 mm for general aesthetics or 0.2 mm for moderate environmental conditions to prevent rebar corrosion. Once all serviceability checks (including crack width and
Once all serviceability checks (including crack width and deflection) are satisfied, BEAMD generates complete reinforcement drawings including longitudinal bar layouts, stirrup arrangements, bar bending schedules, and material quantities. These can be exported to CAD formats or printed directly.
