Abstract

先きに森林鉄道に於ける標準I型鋼橋の主桁の設計について発表したが,引き続き補剛材,綾構等について検討を加えた。その結果,経済的なI型鋼橋とは,支間の長短によつてその考え方を異にすべきであるということが判明した。

In connection with my previous report on the standard steel I-beam bridge for forest-railway, I have investigated some designing problems about the stiffeners, cross-frames, and other attached members of I-beam-bridge, i.e. how to reduce the weight of the structure as a whole. In consequence, it has been comprehended from the economical view point that the weight of the attached members, including stiffeners and cross-frames, might be so designed and constructed to be about 20% of that of the I-beam in the case of 5_??_8m effective span and, about 30_??_55% in the case of 10_??_12m effective span respectively.
