The stresses in web reinforcement may be estimated by means of the following 



formulas: 



Vertical web reinforcement,

Bars bent up at angles between 20 and 45 deg. with the horizontal and web members 

 inclined at 45 deg.,

In the text of the report it is recommended that two- thirds of the external vertical 

 shear (total shear) at any section be taken as the amount of total shear producing 

 stress in the web reinforcement. V therefore equals two-thirds of V. 



The same formulas apply to beams reinforced for compression as regards shear and 

 bond stress for tensile steel. 

 For T-Beams.
