In this paper, the relation between dragcoefficient and project ratio used for design was chosen as a subject of the study. We investigated the wind force acting on pipe-towers by wind tunnel tests and, on the basis of experimental results, clarified that relation. And also the project ratio was applied in stead of the repletion ratio which has been used. As a result the expression of PD (kg) for arbitrary angle was improved to given the simplified empirical equation. But one thing which we would like to mention here is that this wind load means the hours mean of it acting on pipe-towers, etc. Therefore, the vibration with the vortex envolved in slip stream of the tower is not considered. The tower section is delt with nothing but the square section which is well used for a number of free standing tower.
