The investigation objects are section size, material, initial imperfections, stiffener size of compression member which designed based on Spec. for Highway Bridges 2002. In addition, ultimate strength characteristics of existing compression members with box-section are calculated for several steel types. The results of investigations shows that the 0.2σy is able to apply as upper limit of compression residual stress (σrc) for HTSS members. The results of numerical analyses provide the ultimate strength characteristics of welded box-section compression members for steel truss and arch bridges. Moreover, new ultimate strength curve is proposed for the compression members in this research.}, pages = {35--48}, title = {実橋箱断面圧縮部材の耐荷力特性と基準耐荷力曲線に関する検討}, volume = {61}, year = {2015}, yomi = {ノガミ, クニエイ and タケウチ, ユキハル and ヤマシタ, ヨウヘイ and キシ, ユウスケ and ナガイ, マサツグ and オクイ, ヨシアキ and ノザカ, カツヨシ and コムロ, マサト and ミヤシタ, タケシ} }
