  1. V cr is the initial cracking strength; V y , V peak , and V failure are the yield strength, peak strength, shear strength at failure, respectively. Δ cr , Δ y , Δ @Vpeak , and Δ failure are the measured displacement corresponding to the strength of V cr , V y , V peak , and V failure at the mid-span of the test specimen, respectively. μ is the ductility obtained by the equations of Δ failure /Δ y . It should be note that S means the diagonal tension failure; SY is the shear yielding; C is the compression failure of concrete; F is the flexural yielding.
