集材架線の支柱に，主索に対して横荷重が働くときの，各控索に生ずる張力の算定式を，力のつりあいと弾性伸長理論から誘導した。この算定式を用いることにより，各控索に生ずる張力を，控索の索長，断面積，弾性係数，控索と横荷重の方向とのなす角，横荷重，支柱高，支柱基部より控索結合点までの高さ，および控索と水平面とのなす角から正確に求めることができる。We analyzed guyline tensions which are caused by lateral loads against the skyline. The equations to calculate the guyline tensions are derived from the theory of the equilibrium of forces and the elasticity. It is concluded that each guyline tension can be given by the guyline length, sectional area, modulus of elasticity, angle of the guyline against the direction of lateral load, strength of lateral load, spar tree height, angle of the guyline against a level surface, and the height of fixing point of the guyline on the spar tree.
