| Abstract: | Based on the concrete creep experiment combined to the actual engineering, this paper presents the creep characteristic and changing regulation through the theories analysis and the spot experiment. Taking the C50 concrete beam as the main research object, the stress strain and deflection are measured. According to the curve diagraph of creep coefficient - loading time drawn from the related data, the contrast analysis about results between the experiment and the theory is given. |
