A series of studies have been planned to clarify the time-dependent stress-strain behaviors of concrete. The present paper describes firstly the experimental results and discussions of creep phenomena of concrete subjected to high tensile sustained stress. It includes a statistic treatment tried to analyze the tensile creep limit and the time to tensile creep rupture occurance. Secondly, the results of tensile relaxation tests of concrete are given ; the tensile stress relaxation as well as the compressive relaxation can be fully approximated by a hyperbolic equation with two experimental constants representing the relaxation time and the ultimate residual stress, respectively, and the ratio of the ultimate relaxation loss to the unit initial stress represents a characteristic value of relaxation corresponding to the ultimate creep factor.
