프리캐스트 콘크리트조 기초부의 P.C화에 관한 연구(II) ( Precast Concrete Foundation of Large Panel Concrete Structures(2. Shear Test) )

This paper is for the study in shear test on precast ocncrete foundation of large panel concrete structures. Five specimens are composed of one conventioned monolithic specimen and four specimens with P.C.joint. From the test results, it is observed that the shear rigidity and ultimate resistibility of the specimens having horizontal P.C. joint only between the footing girder and footing slab is nearly identical with that of the monolithic specimen. On the specimens with vertical P.C. joint at the footing girder, it appeared that they possess ultimate resistibility twice as much as design strength, even though their ultimate load were showed about 30 percent lower than that of the monolithic specimen. From these, it is concluded that practical use of the P.C. foundation is possible.
