충전성을 개선한 각형CFT 기둥-보 접합부의 구조 특성
박제영,이명재,Park, Je Young,Lee, Myung Jea 한국강구조학회 2013 韓國鋼構造學會 論文集 Vol.25 No.2
CFT구조의 기둥-보 접합부는 강관의 국부좌굴을 방지하기위해 다이아프램이 필요하다. 외측다이아프램 형식은 관통다이아프램 형식보다 콘크리트의 충전성이 좋으나 시공성과 건축설비와 공조하는 측면에서 불편함이 있다. CFT구조 접합부의 상부 다이아프램은 외측다이아프램 형식으로 하고 하부 다이아프램은 관통다이아프램 형식으로 하였다. 이것은 건축물에서 바닥슬래브가 있으므로 상부 다이아프램은 바닥슬래브와 일체가 되고 하부 다이아프램으로 관통다이아프램을 적용하여 건축설비와의 마찰을 피하고자 한 것이다. 결과적으로 충전성을 개선시킨 CFT구조의 구조성능은 상, 하부 모두 관통다이아프램을 적용한 구조와 비교하면 동일하다는 것을 알 수 있다. CFT structures require a diaphragm to prevent buckling of steel at connections. An outer diaphragm has better concrete filling than a through diaphragm due to a large bore, but due to the larger size than the through diaphragm, it has poorer constructability and cooperation with building equipment. The building structure has a floor slab that was unified with the upper diaphragm, so the outer diaphragm was placed at the upper bound. Moreover, the through diaphragmwas placed at the lower connection to avoid obstruction of the building equipment. The CFT structure with the improved concrete filling showed the same structural behavior as the CFT structure with the use of the same type of diaphragms at the upper and lower connections.

The results of the analysis of the 29th Beijing Olympic Men`s Basketball Game are as follow: First, by discriminant analysis, the most important factor for the game result was defensive rebounds(DR). other factor can be ordered by the importance for the game result, and they were assists(AS) and turnovers(TO). Second, Winning teams` rate of success of 2-point shot(2P%) and 3-point shot(3P%) were higher than Losing teams. Winning teams have more number of assist(AS), defensive rebounds(DR) and steals(ST) than Losing teams. Third, the predicted accuracy rate of the game result was 92.1%. and it meant somewhat high cross validity of discriminant equation.

The results of the analysis of the contribution of win-loss factor in the 2000-2001 season korean basketball league are as follow; First, the rate of 2-point shots(2P%), the rate of 3-point shots(3P%), the rate of free throw shots(FT%), assists(AS), fastbreaks(FB), defensive rebounds(DR), steals(ST), good defenses(GD), blocked shots(BS), fouls with free throw(WFT), illegal defenses(ID) had significant difference between win and loss. Second, by discriminant analysis, the most important factor for the game result was defensive rebounds(DR), other factor can be ordered by the importance for the game result, and they were the rate of 2-point shots(2P%), the rate of 3-point shots(3P%), turnovers(TO). steals(ST), fouls with free throw(WFT). Third, the predicted accuracy rate of the game result was 86.22%. and it meant somewhat high cross validity of discriminant equation.
