        This paper presents a foundation pile to steel column connection that can resist large magnitude of moment and that can be easy installed. The developed joint has spherical shape and it is given the name HAT joint to mean Hallow half-sphere steel joint. Four types of HAT joints are developed. Namely, H-type, T-type, P-type and K-type. In this paper I will talk about the performance assessment of T-type(Tube Column) and P-type(Pile Column) of HAT joints with finite element analysis and experiment on a full scale model is presented.

        In Part I, we disccussed of joint between PHC pile and steel column in foundation of large space structures, one prototype of a joint of PHC pile to steel pipe column was suggested on the basis of analytical studies. In this paper, I explain the Joint of PHC pile to steel tube column and more detail of analysis

        To overcome disadvantages of usual spread foundation in large space structure, some prototypes of a joint of the PHC pile to steel pipe column that directly connects a column to a PHC pile are analytically studied. With the consideration of strength requirement and stress concentration of joint of the PHC pile to column, we suggest the most appropriate one.

        연약지반에서 측방 유동에 의해 주변 지반에 큰 변형을 일으키며 이로 인하여 말뚝기초에 손상을 입히게 된다. 이러한 경우 설치된 말뚝을 수동말뚝이라 하며 편재하중이 작용하게 되고 이로 인해 측방토압을 받게 되며 측방변위가 발생하여 상부구조물에 영향을 미치게 된다. 그러나 국내의 경우 이러한 말뚝과 교대 변위간의 관계에 대한 예측 및 메커니즘에 대한 연구가 부족한 실정이다. 본 연구에서는 교대이동에 대한 해석을 위해 입체, 판 및 프레임 요소를 복합적으로 해석할 수 있는 연성 3차원 유한요소해석 프로그램을 개발하였다. 개발된 연성해석 프로그램을 이용하여 연약지반상 형상비(두께-지름비, t/D비)를 변수로 한 교대강관파일의 변형특성을 명확히 하였다.

        It is known that all of structures be old enough not to use as time elapses, and the degree of deterioration depends on the environmental conditions and maintenance activity. Specific repair for deteriorated structures should be applied and the performances are greatly affected by materials used and location of members allocated. This study is to evaluate the enhancement of steel pipe pile in terms of performance when they are reinforced by carbon-fiber composite for underwater.

        This study is to evaluate the enhancement of steel pile in terms of performance when reinforced by primer and impregnated epoxy developed for underwater. Through compressive strength test, the adhesion between original material and new one was to be investigated as well as reinforcing effects.
