清水建設研究報告 第83号平成18年4月 NewRCSS () () () A Structural Behavior of Reinforced High Strength Concrete Column/Steel Beam Composite Frame (NewRCSS Frame System) A Proposal of seismic design for the beam-column joint by Koji Yamanobe, Keiji Nakanishi and Yasushi Watanabe Abstract This paper describes experimentally the structural behaviors of reinforced high strength concrete column/steel beam composite frame (NewRCSS Frame System) to extend the application of the conventional one (RCSS Frame System), and proposes a seismic design for the beam-column joint, including eccentrically-connected beam-column joint. The application can be extended by raising the concrete strength of columns up to 60N/mm2 2 2 from 36N/mm , the yield strength of reinforcing bars up to SD490 (yield strength : 490N/mm ) from SD390. The experimental results showed that the beam-column joints including eccentrically-connected ones can be designed properly by introducing a reduction factor for concrete; and that the several factors for joint elements other than concrete can be taken as the same ones as in the conventional seismic design.
