Shear-flexural strength mechanical model for the design and assessment of reinforced concrete beams subjected to point or distributed loads... The shear strength is considered to be the sum of the shear transferred by the concrete compression chord, along the crack, due to residual tensile and frictional stresses, by the stirrups and, if they exist, by the longitudinal reinforcement....
A mechanical model for failures in shear of members without transverse reinforcement based on development of a critical shear crack... To that aim, the shear force that can be transferred through the critical shear crack by aggregate interlock, residual tensile strength and dowelling action as well as due to the inclination of the compression chord are calculated by integration of fundamental constitutive laws accounting for the critical shear crack opening and kinematics at failure....
Shear design of concrete members without shear reinforcement—a solved problem? ... It is questionable whether this behavior is caused by the vertical component of the inclined compression chord Vcc
