PRACTICE QUESTIONS 1

1. Details of a single-storey steel industrial building located in Dorval QC are provided in Figure 1. Based on previous construction experience in the area, the following information has been specified by the senior design engineer and the architects: Grade 350w wsections, Grade 300W angle sections and base plate material, ASTM A500 Grade C HSS members, 25 MPa concrete strength, roofing and ceiling materials are elastic in nature, roof contains 1.52 mm thick 38 mm deep steel roof deck, 12.7 mm thick fibre board over the entire deck area, 100 mm of rigid foam insulation, 4 ply asphalt roofing with gravel, standard ductwork, the self-weight of the joists has been estimated at O.15 kPa and the selfweight of the beams at 0.20 kPa. A 1.0 kPa occupancy load is to be considered for the roof. Joists at columns, and those immediately adjacent to columns, will have bottom chord extensions.

a) Determine the overall uniform. gravity loads on the roof.

b) Design an appropriate square HSS interior column based on gravity loads (nealect connection eccentricities). Column selection tables may be used for an initial member choice; full design calculations must then be camed out. Once you have designed this column, change the grade to 350W hot-rolled and determine the capacity of an HSS which has the same outer dimensions but is one thickness size less.

c) Design a typical interior Gerber beam and link beam. Use beam selection tables. For the cantilever length, use a distance of 12% of the span between columns. Ignore deflection for this example.
