Abstract
Continuous reinforced concrete (RC) beams are the structural members commonly used in bridges. These structural members have lesser positive bending moment because of which it has lesser maximum deflection as compared to simply supported beam. Due to advancement in technologies, the continuous beams in bridges have to carry heavy loads, but due to restriction for the depth of the beam, it is required to use reinforced high-performance concrete (HPC) beam instead of normal RC beam. Therefore, the use of HPC beams in these types of structures is beneficial. As compared to simply supported beams, very few experimental studies have been investigated on the behaviour of continuous HPC beams. The objectives of this research are to investigate the behaviour of continuous high-performance concrete beams under flexure and to provide design guidelines to predict the failure load and to compare the experimental values with the analytical and theoretical values. This paper presents the experimental results of two reinforced HPC beams with the rectangular cross section of 230 mm × 150 mm continuous over two spans of 1500 mm each. The beams are designed using ACI-318 and are tested under concentrated monotonic loads applied at the midpoint of each span. Further, the same beams are analysed by finite element method (FEM) using ANSYS software.
