How a steel member weight reads straight from its AISC designation (a W24x76 weighs 76 lb per foot), plus reference shapes.
This is the exact table the Crane Cost Estimator runs on. Cite it as: Antero Trail, "Structural steel shape weights (AISC designations)", anterotrail.com/tools/reference/steel-shape-weights. Primary sources are listed with each value and at the bottom of the page.
Weight basis for the steel_beam_set crane scenario (PRP-CALC-2). Primary derivation PARSES the member self-weight directly from the AISC section designation: for W/S/M/HP/C shapes the integer after the 'x' is the nominal weight in lb/ft (AISC naming convention, cited). member_length_ft x lb/ft = member self-weight; the derivation adds a stated rigging allowance. The reference_shapes table below is a spot-check of common sections (value = lb/ft = the designation suffix), not the compute path. No cited lb/ft table was located for open-web steel bar joists or steel/CFS trusses; those require a user-supplied weight from the shop drawing.
Open-web steel joist self-weight is NOT encoded in the K/LH designation; it appears on the SJI load table / shop drawing. v1 requires a user-supplied weight. TODO(backlog): add a cited SJI K-series lb/ft table.
