Title: Behavior of Concrete Under Biaxial Stresses
Author(s): Helmut Kupfer, Hubert K. Hilsdorf, and Hubert Rusch
Publication: Journal Proceedings
Appears on pages(s): 656-666
Keywords: biaxial stresses; compressive strength;concretes; plain concrete; research; strains;stresses; stress-strain relationships; tensile strength; test equipment.
Abstract:Experimental studies into the biaxial strength of concrete are reviewed and technical difficulties encountered in the development of a suitable test setup are discusssed. A new testing apparatus is described which allows testing of concrete specimens under various biaxial stress states. Results of an investigation for which this equipment was used are r e orted. The test data indicate that the strength of concrete under biaxial compression, 01 = 02, is only 16 percent larger than under uniaxia I compression. Tests in the region of combined compression and tension confirmed previously obtained data. The biaxial tensile strength of concrete is approximately equal to its uniaxial tensile strength.
