This paper presents a method of obtaining shear cracking prediction model of both crack spacing and crack width of Reinforced Concrete (RC) beam, respectively. Essentially, the proposed prediction model for crack spacing is from the modification of the harmonized model used by the previous researcher. Whereas, crack width is from the flexural cracking caused by the combination of primary and side reinforcement and the cracking contribution of shear reinforcement. The proposed prediction model presents a more generalized approach for estimating shear crack spacing and shear crack width of RC beam with side face reinforcement.
