An experimental st.udy of the strength of concrete under combined tensile and compressive stresses was undertaken by loading hollow concrete cylinders to failure. Circumferential tension was developed by internal hydrostatic pressure, and axial compression was produced by end loading in a conventional testing mdchine. Compressive and tensile strengths were both reduced in the presence of an orthogonal stress of opposite sense. Test results are presented in terms of principal stresses and of octahedral normal and shearing stresses. In neither cake does a simple linear relationship between stresses define the failure conditions sstiafactorily throughout the full range from eimple tension to simple compression.
