EXPERIMENTAL STUDY OF COMPLETE TENSILE STRESS-STRAIN CURVES OF HIGHSTRENGTH CONCRETE AND COMPACT REINFORCED CONCRETE
Experimental study of complete tensile stress-strain curves of high strength concrete and compact reinforced concrete was conducted. Two sets of test devices, were designed. The deviations of the measured complete curves are small, indicating that the devices are effective. In addition, the theoretical equations of complete curves are proposed and compared with measured ones. Good agreement is reached.
