초록

The shear behavior of foundation is evaluated the same as slab under the current building code (ACI318-08 and KCI-07). But the shear behavior of foundation would be different from the behavior of slab received uniformly distributed load, because it changes according to the deformational pattern of the foundation plate and the distributional pattern of the bearing power of soil.
This paper examined the behavior of the foundation structure as well as the reinforcement effects associated with the reinforcement details. Toward such end, a series of tests were performed on three types of specimens (a non-reinforced RC specimen and two reinforced specimens, with welded/non-welded joint working as factors) installed on the ground. The conclusions obtained from the test data are summarized below.
With regard to the use of welding for the joints of the reinforcement, the non-welded specimen exhibited a lower level of punching shear capacity compared to that of the welded specimen, although only minor differences were found between the specimens in terms of ultimate load and behavior.
