Shigeru KURANIS111* and Tetsuya Y ABUKI" 2. CONSIDERATION OF RESULTS The arches subjected are confined to twohinged palabolic steel ones and a general view of them is shown in the inset of Fig. 3. Shinke, Zui and Namita made a series of precious tests concerning steel arches having rectangular cross sections with practical slenderness ratios and reported instructive results in Ref. 2). We shall refer to their experimental
The normal stress distribution and cross-sectional deformation by distortion in single span curved box-bridge-girders have been investigated. An analytical modeling by so-called Beam on Elastic Foundation (BEF) analogy for the distortion is verified experimentally by testing programs. On the basis of the parametric studies by the BEF analysis, a spacing provision by which the distortional stress can be kept within the level of secondary stress is developed. Design examples specified by the proposed provision are also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
