Abstract: Most of the current shear strength design provisions for reinforced concrete (RC) members with fiber-reinforced polymer (FRP) bars are empirically derived or calibrated by using different data sets. Therefore, a reliable database for developing or comparing such provisions with test results is of vital importance. In this paper, a database of shear tests on FRP-RC members was collected from published test results. This data set initially included 754 tests, and after applying several control and filtering criteria, two evaluationlevel databases for slender members were developed. Then, the databases were used to evaluate the accuracy of the shear strength provisions from six current design guidelines and two other design models. It was determined that CSA S806-12 provided more accurate predictions for members without or with FRP stirrups than other methods considered in this study, while the ACI 440, JSCE, and Modified Compression Field Theory (MCFT)-based methods provided more conservative predictions, with a measuredto- predicted ratio between 1.31 and 2.60.
