326 СНАРТER 6 BENDING EXAMPLE 6.18 The reinforced concrete beam has the cross-sectional area shown in Fig. 6-39a. If it is subjected to a bending moment of M = 60 kip ft determine the normal stress in each of the steel reinforcing rods and the maximum normal stress in the concrete. Take Est = 29(10) ksi and Econc = 3.6(103) ksi SOLUTION Since the beam is made of concrete, in the following analysis we will neglect its strength in supporting...

Question #2 (20 points) A (a) A Composite column made of reinforced concrete was constructed on a very rigid foundation. The column was constructed at 25 °C and in this temperature, there was no stress in the system. The column is exposed to axial loading (or stress) of 2000 psi as shown in the picture. The column has a thickness of 8 in, a width of 3 in, and a length of 13 ft. Six #6 longitudinal bars (each has...
