:rocket: We’ve released an updated Steel Composite Beam (LRFD) calculator aligned with AISC 360-22, expanding support for composite behavior, construction stages, and serviceability checks with clearer assumptions and more transparent results.

:magnifying_glass_tilted_left: What’s included in this update

This calculator designs and analyzes steel beams acting compositely with concrete slabs using LRFD, with support for:

  • Composite and precomposite bending strength

    • Plastic moment resistance for positive and negative bending

    • Plastic and elastic neutral axis determination

  • Shear connector design

    • Nominal shear strength of individual and total stud anchors

    • Required number of studs and longitudinal/transverse spacing checks

    • Composite action limits (25%–100%)

  • Construction-stage behavior

    • Shored and unshored construction

    • Wet concrete and deck self-weight effects

    • Precomposite flexural stiffness and deflections

  • Serviceability checks

    • Lower-bound elastic moment of inertia

    • Long-term and short-term deflection limits

    • Optional precamber consideration

  • System flexibility

    • Metal deck or solid concrete slab

    • Deck orientation parallel or perpendicular to the beam

    • Continuous beams with multiple supports and load combinations
