The simply supported beam in Figure below supports uniformly distributed characteristic dead and imposed loads of 7 kN/m and 5 kN/m respectively, as well as a characteristic imposed point load of 30 kN at mid span. Assuming the beam is fully laterally restrained and there is nominal torsional restrain at supports. Check the suitability of 406 × 178 x 85 kg/m UB section in S275 steel to satisfy bending, shear and deflection considerations. RA 30 kN imposed load QK = 5 KN/m Gk = 7 KN/m C 10 metres Ra

The service load bending moments on a beam are 128 kip-ft for dead load and 107 kip-ft for live load. The beam is 12 in. wide, f'c is 3000 psi and fy is 60 ksi. Determine Mu. Mt. p. R. the depth of the beam and the As of tensile reinforcing required. How many no. 8 bars or No. 10 bars would have the required As?

For the structure shown in Figure, with a uniformly distributed service dead load wD= 1.5 kips/ft and a uniformly distributed service live load wL= 2 kips/ft applied to beam BC, answer the following questions: 1. Find the minimum area of steel required to serve as a cross section for member AB. Assume welded connections and shear lag factor U = 0.75 2. Find the lightest standard rolled W section to adequately resist the bending moments in beam BC. Assume that the top flange is laterally braced at points B, C, and at midspan. Compute the value of the bending coefficient cb.
