CORRUGATED BAR COMPANY, INC. 



If it is required to maintain a minimum depth of beam it will be found that a 14*' x 22" 

 beam, reinforced with Q-J/g" round bars will carry the load. It will be noted, however, 

 that the shallower beam requires more steel and concrete. 



To determine the number of stirrups required for the 10* x 26" beam, find the end 

 shear. 



(2.062) (f ) 

 (I) (10) (23) 



= 113 lb. per sq. in. 



From the table on page 107 for an end shear of 120 pounds per square inch a 10-inch 

 beam of 22 foot span requires 20-^" round stirrups, and for an end shear of 100 pounds 

 per square inch^l4-^" round stirrups. As the actual end shear is 113 pounds per square 

 inch, by interpolation, 18-^" round stirrups will be suflBcient. 



In the tables which follow the endeavor has been made to give a fairly wide range of 

 values from which to make the desired selection of size of member and reinforcement 

 required, so that knowing the load and span the designer may enter the tables 

 and choose the beam or slab which best meets the needs of his particular case, 

 much as he would select a beam from a safe load table in a structural steel hand- 

 book.
