Question: A simply supported beam and its loading are shown below. What is the largest size of bar that can be used for the flexural reinforcement,

A simply supported beam and its loading are shown below. What is the largest size of bar that can be used for the flexural reinforcement, without the use of hooks or headed bars? Assume the bars will be epoxy coated and this beam will be reinforced with at least code minimum stirrups. Also assume there is clear spacing between the bars of at least

d_{b}

and the clear cover is at least

d_{b} .

The steel is Grade

60,

and the concrete is normal weight with a compressive strength of

4500

ksi.
