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.
