본 연구에서는 합성보의 특징을 활용하고, 일부 고강도강 적용이 가능한 단면을 개발하여 이에 대한 기초연구를 실시하였다. 본 논문은 그 첫 번째로 단위부재인 합성보의 휨성능을 실험을 통해 평가하였다. 실험결과를 통해 기존 합성보의 공칭강도 산정식 적용여부를 검토하였고, 각 구성부재를 주요변수로 하여 실험하였다. 실험결과 신형상 U형 합성보의 내력평가는 콘크리트 압축강도와 강재의 인장강도에 의한 우력모멘트로 소요모멘트에 저항하는 것으로 평가하는 것이 적합하며, 보 춤 및 강판 두께에 비례하여 내력이 안정적으로 증가하였으며, 연성거동을 하는 것으로 나타났다. In this research, we carry this study into effect on the basis of utilizing character of composite beam and developing applicable section to some of high strength steel. We evaluated flexural capacity of composite beam that is a unit member through experiments. The existing nominal strength formula of Composite Beam which is a previous method was reviewed and the experiment had been progressive by using each composite members as main variables though the result. Capacity evaluation of U-shape Hybrid Forming Beam(HyFo Beam) which is a new shape show as follow from the result. First, it is resonable to resist demand moment by couple moments which are occurred in concrete compressive-strength and steel tensile-strength. Second, the capacity was stably increased in proportion to the depth of beams and the thickness of steel plates. The last, HyFo Beam was showed as ductile behavior.

Exfoliative dermatitis is a name of a group of symptoms which is characterized by red rash, itching and scale in almost whole body. The patients are suffered from hypoalbuminemia, general weakness and fever sign in addition to characteristic skin lesions. So in the treatment of this disease, adequate symptomatic treatment is important with adequate topical skin management. We experienced a 67 year old Korean male patient diagnosed as exfoliative dermatitis based on clinical symptoms. We concluded that the symptoms of this patient are Sun-symptoms(癬症) and gave him Sunpunghwangi-san(宣風換肌散) and Chungdae-san(靑黛散). After taking herbal medicine, clinical improvement was noticed. Based on this experience, both internal and external use of oriental medicine have a good effect on exfoliative dermatitis.

H형강 기둥에 대한 신형상 약축접합부를 개발하여 단조가력실험을 통해 구조성능평가에 관한 연구를 수행하였으며, 선행연구결과를 바탕으로 본 연구는 시공성을 고려한 신형상 약축접합부의 내진성능을 평가하기 위해 반복가력실험을 실시하였다. 신형상 약축접합부는 접합개소 및 용접량이 적고 접합상세가 단순하며, 접합부에 작용하는 힘의 흐름이 명확하다는 장점이 있다. 이에 따라 H형강 기둥플랜지와 보 단부의 겹침길이를 실험변수로 한 신형상 약축접합부(WPL-WK-FC2, WPL-WK-FC3)와 건축강구조 표준접합상세지침에 근거한 표준 약축접합부(HH-WK-FC4) 총 3개의 실험체를 실물대 사이즈(Full-scale)로 제작하였다. 실험결과, 신형상 약축접합부는 0.04 rad 이상의 층간변위각에서 보 소성모멘트(<TEX>$M_P$</TEX>)의 80%이상을 유지하는 특수모멘트골조(SMF)의 내진성능을 확보하였으며, H형강 기둥플랜지와 보 단부의 겹침길이가 50 mm 이상이면 시공성 뿐만 아니라 구조적으로 우수한 것으로 나타났다. H-section steel column new shape weak-axis was developed and performed through monotonic loading test regarding basic structural performance evaluation. In this study cyclic loading test was followed up in order to evaluate seismic performance through the full-scale of new shape weak-axis connection for constructabilitiy. New shape weak-axis connection has a simple shape with the less spot of welding points, and it has advantage about showing the obvious flow of strength in connection points. Therefore, three specimens are built for the variables which are overlap length of beam-end and column flange. As the result, New shape of weak-axis connection is appeared special Moment Frame(SMF) and have excellent structural performance and constructablility when the parameter is over 50 mm.

신형상 전단연결재를 적용한 철선일체형 데크플레이트의 성능평가

김성배,강민정,황보찬,김상섭,Kim,Sung Bae,Kang,Min Joung,Hwangbo,Chan,Kim,Sang Seup 한국방재학회 2014 한국방재학회논문집 Vol.14 No.3

철선일체형 데크플레이트는 시공의 편의성 및 공기단축으로 건설현장에서 널리 사용되고 있다. 일반적으로 데크플레이트는 강구조에 적용되므로, 강재보와 철근콘크리트 슬래브의 경계면에서 작용하는 수평전단력에 저항하기 위해 전단연결재를 설치한다. 또한 시공 중 데크플레이트의 탈락 및 바람에 의한 낙하 등을 방지하기 위해 철선트러스가 끝나는 양단부의 상부철선에 직봉을 설치한다. 그러므로 강재보 상부에는 전단연결재와 직봉이 중첩된다. 이에 본 연구에서는 전단연결재와 직봉의 기능을 겸하는 새로운 형상의 전단연결재를 개발하였으며, 30개의 실험체를 제작하여 시공 중 철선일체형 데크플레이트의 구조적 안전성을 평가하였다. 실험결과 신형상 전단연결재는 직봉의 역할을 충분히 대체할 수 있을 것으로 판단된다. Recently, due to the decreased work term and the convenience of construction work, the steel wire-integrated deck plate has been widely used in the construction sites. In deck plate, Shear connectors are installed to resist horizontal shear force on the interface between steel beams and reinforced concrete slabs. Also vertical bars are installed at upper wire of the ends of steel truss girder to insure safety during the construction. Therefore, this study attempts to develop the new-type shear connector which function as vertical bars while securing a higher shear capacity, and tests have been conducted on 30 specimens to evaluate the structural safety of the proposed deck plate system during the construction step. The test results show that the new-type shear connectors sufficiently perform the roles of the Vertical bars.

김성배,최승관,이창남,김상섭,Kim, Sung Bae,Choi, Seng Kwan,Lee, Chang Nam,Kim, Sang Sup 한국강구조학회 2006 韓國鋼構造學會 論文集 Vol.18 No.1

복합 구조 시스템은 강재와 콘크리트의 합성으로 내화성능이 우수할 것으로 판단된다. 그러나 복합구조의 내화성능에 대한 연구는 아직 초기 단계로 기둥과 보 등의 부재에 대한 내화실험 결과가 일부 발표 되었으나 합성보에 대한 자료는 거의 없다. 이에 본 연구에서는 TSC 합성보의 내화성능 평가를 위해 내화실험과 수학적 및 수치 해석적인 방법을 통해 평가하였다. 내화실험은 형상의 종류와 가력 하중, 내화피복재 보강방법 등을 변수로 실험을 실시하였다. 또한 수치 해석 중 강재와 콘크리트의 재료특성은 Eurocode에 준하였으며 온도의 변화는 열전도 FE 해석과 수학적인 방법을 사용하였다. The purpose of this paper is to evaluate the fire resistance of the TSC beam, a composite beam composed of a concrete beam enclosed by steel plates. Since a discrepancy was observed between the structural mechanisms of TSC and typical composite beams, the fire performances of the two beams are likewise believed to be partially dissimilar. In this experiment, small and medium-sized TSC beams were tested under given conditions in the laboratory, with/without one of the most widely used spray-on fire protections in Korea. Furthermore, based on the steel and concrete properties under elevated temperatures that were obtained from Eurocode, temperature development across the section was suggested, analyses. To determine the capacity of a modified plastic section, th e fire performance of the model was also examined.
