A W310 x97 steel wide-flange section Supports a uniformly distributed line load on a simple span of 7 m. Assume A36 steel. Calculate the allo kN/m). Neglect the weight of the beam. Use Fy=0.4 Fv

s shown in the sketch, an interior column AB in a steel frame carries a factored axialcompressive load, Pu = 1540 kips. The column is braced at the top and bottom and the mid-height in the perpendicular plane, and sidesway in the plane of the steel frame is allowed. Thecolumns are 12-ft long, and the columns above and below the column AB are the same size asAB. The adjacent girders are W 18×50 and are 32-ft long. Use A992 steel with Fy = 50 ksi,select the lightest W-section for the column AB. Use stiffness reduction factor where applicable.

A simply supported rectangular beam 400 mm wide having an effective depth of 550 mm carries a total factored dead load 30 kN/m and a total factored live load of 50 kN/m. If the span is 6 meters, compute the 3- legged 10 mm stirrups spacing required. Use fc' = 21 MPa, fy = 345 MPa and fyv = 276 MPa O 138 O 168 O 140 O 148

Problem 2 A loaded cantilever beam is shown. E=29,000 ksi. The W16 section that will limit the total load deflection at the free end of the beam, B to 0.75 in. is most nearly: WD = 0.5 k/ft WL = 1.0 k/ft PD= 2 k B PL = 4 k Answer: W16 x L = 12 ft %3D
