Based on the shear design method of prestressed concrete (PC) beams (UH method) and on the concept of effective web area by Tureyen and Frosch, a shear design method for reinforced concrete (RC) beams that was consistent with that for PC beams was presented in this paper. Instead of using the web area bwd as a variable in the Vc term of the UH method, Eq. (13) used the web compression area bwc, but all other parameters remained the same. Meanwhile, compared with Eq. (11), the coefficients in Eq. (16) were modified. Even though these proposed equations were verified using 313 RC beams available in the literature, the derivation process for such changes still need to be supplemented. To compare the results of Vs calculated by the proposed method and ACI 318-11, test data of 74 pairs of beams has been obtained here by considering 13 papers available in the literature.
