THE SERVICEABILITY CONSIDERATIONS OF HSC BEAMS

摘要

To investigate the serviceability conditions of High Strength Concrete (HSC) beams, the total number of 12 beams (L=2 m, b=0.2 m, h=0.3 m ) with different ratios of prnand p' are cast and tested under bending loads. During the test the concrete and steel strains, deflection and crack width are measured at different beam locations. Based on these experimental observations, the moment of inertia (I_(cr)) of HSC beams are found and the results are compared with the different available theoretical methods. Generally, the serviceability and post serviceability behavior of HSC beams is improved whereas, it was concluded that the (I_(cr))_(cxp) values are lower than the theoretical (I_(cr))_(th) values.
