The article discusses compression tests designed to estimate actual stresses likely to cause a concrete member to fail under compression by either diagonal shear or lateral tension. Compression tests were carried out on concrete prisms of 200 x 100 mm with h/d ratios of 0.5 to 3.0 as well as cube tests. Two series of tests were carried out with, and without, cardboard liners between the prisms and the steel platerns. The minimum crushing load was found to occur at h/d = 1.7 with the liners, and at 2.0 without, for six week old concrete. The conclusions examine the failure of concrete compression members by splitting, although reinforced members would usually fail by simultaneous buckling of the main bars and shearing of concrete between the links. The importance is shown of friction between the concrete test piece and the machine platerns in reducing the strain energy of distortion and increasing axial strain energy. This in turn affects the failure shape. /TRRL/
