In order to construct foundation beams using half precast concrete technique, authors have investigated to confirm the uniformity in the process of execution and the uniformity of structural members as finished products. The square test speciments without joint of the precast concrete forms have been manufactured by techniques of half precast concrete and in-site concrete, and its uniformity has been shown only by bending test. In this paper, bending test results and shearing test results of rectangular beams joining the part of precast concrete forms are discussed for test speciments manufactured by techniques of half precast concrete and in-site concrete. As the results of comparison, it is obtained that structural property of the test specimens with joint manufactured by technique of half precast concrete is very similar to the test specimens manufactured by in-situ concrete technique under the shearing force or the bending-shearing force. And also, it is not until reinforcing bars yield that the structural property is similar under the pure bending condition. Therefore, results of various tests of rectangular test specimens with joint using half-precast concrete technique are shown the uniformity of the half-precast concrete part and other part.
