Modifications to ACI 318 shear design method for prestressed concrete members: Detailed method

[摘要] Through extensive research studies conducted in thepast few decades, it is known that the shear strengthof a concrete beam depends on various design parameters, including the following:• compressive strength of concrete f ′c• effective beam depth d• shear span-to-depth ratio a/d or Mu/Vud, where a is shearspan, Mu is factored flexural moment, and Vu is factoredshear force• longitudinal tensile reinforcement ratio ρwt• axial force or prestress Nu/Ag or fpc, where Ag is grossarea of concrete section, fpc is concrete compressivestress after allowance for prestress losses, and N is factored flexural moment• shear reinforcement ratio ρv fyt/ fc , where fyt is yieldstrength of transverse reinforcement and ρv is transversereinforcement ratio.
