Abstract
The behavior and shear strength of lightweight self-consolidating concrete (LWSCC) beams reinforced with basalt fiber-reinforced polymer (BFRP) bars were investigated. A total of four large-scale reinforced concrete beams without stirrups were constructed. Tests were carried out on three rectangular beam specimens using LWSCC; the remaining one, serving as a reference beam, was cast of normal weight concrete (NWC). The beams measured 3100 mm in length, 200 mm in width, and 400 mm in depth. All beams were tested in four-point bending up to failure. The test variables included the concrete type, the longitudinal reinforcement ratio, and the reinforcement type. The experimental results of these tests are presented in terms of crack patterns, load–deflection behavior, and failure modes. In addition, the experimental results are compared to the predicted shear strength according to the CSA/S806-12 (2012) code. A reduction factor is found to be required for predicting the shear strength when LWSCC is used with BFRP bars and hence a reduction factor should be addressed for LWSCC.
