The Serviceability Considerations of HSC Heavily Steel Reinforced Members under Bending

To investigate the serviceability conditions of High Strength Concrete (HSC) beams, the total number of 6 beams (L = 2 m, b = 0.2 m, h = 0.3 m) heavily reinforced with different ratios of p and pʹ were cast and tested under bending load. During the test the concrete and steel strains, deflection and crack width are measured at different beam locations. Based on these experimental readings, the bending rigidities (EI) of HSC beams are defined and the results are compared with the different available theoretical methods.
