| Abstract;Tensile creep of concrete is an important factor which has influence on crack behavior. In this paper, in order to develope the prediction method of the tensile creep strain based on micro mechanism, the observation of micro pore behavior of concrete under sustained tensile stress is carried out and micro mechanical prediction model is organized. By using this model, the tensile creep strain of concrete depending on loading stress, loading age and water cement ratio is predicted correctly. In terms of temperature effect, it is shown that this model may generally predict tensile creep strain of concrete from the comparison with the data of the past literature. (author abst.) |
