This paper describes compressive and shear tests on specimens in which the lateral prestress are introduced by the transverse reinforcement of a reinforced concrete column. In reinforced concrete structures, the columns which are subjected to axial force develop a three-dimensional compressive stress condition, if it is possible to confine the core concrete laterally by introducing prestress with transverse reinforcement, then it is considered that the compressive strength is improved. From the compressive or shearing tests of reinforced short columns in which the prestress is introduced to lateral side by transverse hoops, the following facts are indicated. 1) The lateral prestress introduced by the transverse reinforcement is a very effective method for improving the compressive or shear strength. 2) In shear strength formula, the new idea which introduces the confined effect on concrete is possible.
