In order to determine the shape and size of structure, the formwork must be designed to be strong enough to prevent movement, entanglement when concrete is poured. In the case of concrete with high fluidity, there is no established method for evaluating lateral pressure, so a method of calculating hydraulic pressure is adopted so that the evaluation is on the safe side. In this study, when using high fluidity concrete in the normal strength range, the effect on the lateral pressure of the conventional formwork was confirmed by a full-scale experiment, and the structural calculation of the formwork was examined.
