PROBLEM Authorities of the Atherton Tablelands in North Queensland proposes a glass covered 3m long walkway scenic lookout to cater for tourists. The glass panels are to be attached to an aluminium frame attached to a reinforced concrete beam. You are required to design the reinforced concrete beam Gla Safety post up Thick glas SIDE VIEW FRONT VIEW Figure 1. Schematic View of the Walkway Structure To hold the aluminium frame/glass panels and to allow the tourists to walk in...
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 =...
QI A cantilever steel beam of length L 7.5 m carries both a uniformly distributed load w of 20 kN/m throughout its length and a point load P of 10 kN at its free end, as shown in Figure QI (a). The beam is made from a rectangular hollow box section with a width of 300 mm and a depth of 450 mm (refer to Figure Q1 (b)). The wall thickness of the box section is constant throughout which is...
A simply supported reinforced concrete beam of 8 m span is subjected to uniformly distributed load as shown in Figure 3. The following data are given: The ultimate load, wu is 60 kN/m; characteristic strength of concrete, fck is 30 N/mm²; characteristic strength of reinforcement, fyk is 500 N/mm2. The effective depth, d is 650 mm. Take the link diameter, w as 10 mm, main bar diameter, o as 20 mm and concrete cover as 30 mm. Design the shear...
x Incorrect Two beams support a uniformly distributed load of w = 28 kN/m, as shown. Beam (1) is supported by a fixed support at A and by a simply supported beam (2) at D. In the unloaded condition, beam (1) touches, but exerts no force on, beam (2). Beam (1) has a depth of 300 mm, a moment of inertia of 11 = 125 x 106 mm, a length of L = 3.4 m, and an elastic modulus of...
