A concrete beam similar to that shown in Figure 13.18 sustains a uniform live load of 1.5 klf and a uniform dead load of 1 klf on a span of 20ft. Determine the layout for a set of No. 3 U-stirrups using the stress method with fy = 40 ksi and f ′ c = 3000 psi. The beam section dimensions are b = 10 in. and d = 23 in.
