Abstract
In this study, the distribution of restraining ratio in concrete wall specimens with different shape, number of layer and span and so on was investigated by experiments and FEM analyses, in order to prepare eventually the material design method for controlling shrinkage cracking of RC structure. The following findings were obtained as the result. (1) The distribution of restraining ratio in walls should be considered by dividing into “edge area” in which Bernoulli-Euler's hypothesis stands up and “non edge area” in which this hypothesis doesn't stand up. Additionally, the same is equally true in the wall composed of multilayer and multi-span. (2) “Non edge area” appears when the length-to-height ratio of the wall is higher than some value. (3) The distribution of horizontal restraining ratio in “non edge area” can be calculated by replacing a wall with a uniaxial model.
