222 REINFORCED CONCRETE CONSTRUCTION 



supports and the positive bending moment at the center of span are 

 figured by the formula ~ - The tensile steel at the center of span 

 consists of four 1-in. round bars, b' = 10 in. d = 25 in. Design the 

 supports assuming -y- =0.15. Assume two of the rods to be bent up 



and lap over the top of the supports. Consider the other two rods to 

 lap at the bottom of beam.
