JOURNAL FREE ACCESSFramed structures composed of steel beams and concrete-filled tubular-steel (CFT) columns have generally been adopted in CFT structures. Beam-to-column connections in framed structures are fundamental elements. They have an important effect on the structural behavior of framed structures, in the same way as beams and beam-columns. A number of studies have been performed to clarify the structural behavior of beam-to-column connections. Furthermore, various types of beam-to-column connections have been developed to improve productivity of steel-work and site work. This paper outlines conventional and newly developed beam-to-column connection systems, research activities aimed at clarifying elasto-plastic behavior, and models for predicting strength and restoring force characteristics of beam-to-column connections.View full abstractDownload PDF (1404K) -

JOURNAL FREE ACCESSThe use of slag, a by-product from ironworks, as concrete aggregate has been restricted in the standard specifications for design of concrete structures, because unspecified minerals in the slag may cause some damage on reinforced concrete structures. Recent studies showed that the expansion of the slag can be effectively controlled if steam processed slag is used with fly ash, which enabled the application of the material to some shore concrete structures. However, the mechanism of the expansion has not been fully understood. This report describes the research results on the expansion and control mechanism of blast furnace and steelmaking slag in concrete without natural aggregate (FS concrete). Also, the properties of the FS concrete such as strength, seawater resistance and the behavior of the reinforced concrete members using FS concrete are demonstrated in this paper.View full abstractDownload PDF (17602K) -

JOURNAL FREE ACCESSAt present the reinforcing bars which require the yield strength of less than 490 N/mm2 are standardized by JIS G 3112 “Steel Bars for Concrete Reinforcement”. For steel bars whose yield strength exceeds the above mentioned value, new standard proposals have been made by the National Product Study as New RC. This report discusses the problems of JIS and New RC Drafts and also the differences between those and the proposed standards made by the author. The report introduces the standards for mechanical properties required for higher strength reinforced bars by showing earthquake damages, structural experiments and analyses. The report also contains the mechanical property data of high strength reinforcing bars manufactured with the proposal standard for high rise reinforcing bars.View full abstractDownload PDF (1913K) -
