A simply supported composite beam 3 m long carries a uniformly distributed load of intensity q= 30 kN/m (see figure)
A simply supported composite beam 3 m long carries a uniformly distributed load of intensity q= 30 kN/m (see figure). The beam is constructed of a wood member, 100 mm wide by 150 mm deep, and is reinforced on its lower side by a steel plate 8 mm thick and 100 mm wide. (a) Find the maximum bending stresses σw and σs, in the wood and steel, respectively, due to the uniform load if the moduli of elasticity are Ew =...

A Class 1 post-tensioned rectangular concrete beam is simply supported over a 10 m span. The characteristic imposed load consists of a single 50 kN force at midspan. The characteristic concrete strength is 50 N/mm2 and the unit weight of concrete is 25 kN/m. The beam is of a uniform section (Fig. 5) having the following properties: b- 250 mm; h 500 mm. Assume the concrete strength at transfer is 40 N/mm2 and there is no prestressed loss. (1) Determine...
