Pile cap of caisson foundation is supported by the round area on the side walls and the shear-span ratio is considerably small. But the design method for shear of this member under eccentric loading is not established. We conducted the shear tests for pile cap models of caisson foundation to determine the shear strength. As a result, it is observed that the shear strength decreases in accordance with reduction of effective shear resistance area of the member under eccentric loading.
