In many instances, plate girders are tapered so that the resistance to bending is proportional to the bending moment, creating cost effective, aesthetically pleasing structures. The AISC 2010 Specifications accurately predict the flexural capacity of tapered plate girders but recent research has suggested that the required shear strength is overly conservative. The researchers postulate that the required shear strength is overly conservative due to an effect known as modified shear that has been neglected from the AISC 2010 Specifications but has been suggested by several authors. This research investigates both analytically and experimentally, tapered member ultimate shear strength considering a “modified” and “unmodified” applied shear approach. A new design formula introduced by ...

Web shear strength is a critical limit state for these members because they usually have slender webs.
