重力式砂防堰堤における3次元応力の研究

Abstract

The "sabō" -dam may be considered the twisting and crossing structures, divided into many members of the vertical and horizontal elements. The deflection of the vertical cantilever is equal to the deflection of the same crossing point of the fixed horizontal beam, the twisting angle of the cantilever is equal to the deflectional angle of the fixed beam, and the deflectional angle of the cantilever is equal to the twisting angle of the fixed beam. Analising 1 st order equations, the divided external forces of the fixed beams and cantilevers are given. By this analyzis, the sectional area of the "sabō" -dam is determined more economically than that is analysed by the gravity method.
