A reinforced concrete T-beam carries a uniformly distributed super-load on a simply supported span of 8 m. The stresses in the steel and concrete are not to exceed 125 MN/m2 and 7 MN/m2, respectively. The modular ratio is 15, and the density of concrete is 2400 kg/m3. Determine the permissible super-load.

Figure Q2 shows an 11 m long steel beam AC of uniform cross-section, simply supported at left end A and roller supported at location B. A uniformly distributed load of 40 kN/m is applied on the part AB of the beam together with a concentrated load of 20 kN at the end C. 20 kN 40 kN/m В. 8 m 3 m

Question 1 A composite beam ıs constructed from a wood beam (75 mm wide, by 150 mm hıgh) and a steel plate 75 mm wide The wood and the steel are securely fastened to act as a single beam Calculate the required thickness of the steel plate if the allowable compressıve stress ın 11 the wood is 14 MPa and allowable tensıle stress in the steel plate is 110 MPa GIven that the composite beam is subjected 1 2 to a positive bendıng moment M 8.5 kN.m, calculate maximum bending stress in the wood Assume that Ew 11 GPa and Eg = 200 GPa.
