Question 1 [35 marks] Fig. Q-1 shows a two-span continuous T-beam BCD with overhangs AB and DE. The beam is subjected to uniform loads, gk = 20 kN/m (inclusive of self-weight of beam), and qu= 12 kN/m. Given: fex = 30 MPa and fix = 500 MPa. (a) Determine the load combination that will give the maximum bending moment at support C. Assume minimum design load to be 1.0g. and determine the maximum bending moment at support [10 marks) 6) Design the section at support for flexure, assuming 20% moment redistribution. Use design formula and show the required steel reinforcement on a cross-section. Assume a cover of 50 mm to the centre of longitudinal bars.
