A wide flange steel beam supports a permanent concrete masonry wall, floor slab, architectural finishes, mechanical and electrical systems. Determine the uniform dead load in kips per linear foot acting on the beam.
The wall, made of 8 inch concrete masonry partitions with an average weight of 90 psf, is 9.5 ft high, non-load bearing and laterally braced at the top to upper floor framing. The composite concrete floor slab construction spans over simply supported steel beams, with a tributary width of 10 ft, and weighs 50 psf.
The estimated uniform dead load for structural steel framing, firproofing, architectural features, floor finish and ceiling tiles equals 24 psf, and for mechanical duct, piping and electrical systems equals 6 psf.
The figure has the wall ontop the concrete slab connected with duct and piping. The steel beam is fireproofed. There is also ceiling tile hanging under the beam connected to the slab so the wall, slab, duct, piping, celing tile, and beam itself all contribute to the dead load on the beam. The final answer is 1.66 kips/ft but I do not know how to derive the answer.
