Research at The University of Texas has been conducted to determine the properties and micro-cracking behavior of high-strength concrete subjected to biaxial tension-compression stresses. Static tests and microcrack mapping was performed on 35 specimens which consisted of 5-in. square x 1/2-in. thick plates cut from concrete beams. Tests were performed in a biaxial test machine developed at The University of Texas. The primary variables studied were the discontinuity and ulitimate stress levels at each stress ratio. The microcrack patterns and total crack lengths at various pre-and post-discontinuity stress levels were mapped and recorded. Results indicated that even small amounts of tensile stress reduced stress reduced the ultimate compressive strength of the specimens dramatically. The uniaxial strength of the plates was 75 percent that of standard 4-in. x 8-in. cylinders when both were tested at 172 days after casting. Young's modulus of elasiticity was found to be 3 percent higher for specimens loaded in tension than compression. Keywords: Biaxial tests, High strength, Concrete microcracking.

Over the last decade, the use of high performance concrete has steadily increased throughout the world, particularly in the construction of tall buildings and bridges. This increased availability has been accompanied by a continuing search for improvements in the mechanical properties, methods of production and durability of this material. Inclusion of examples and case studies drawn from throughout the world. Also includes coverage of both theory and practice; and an explanation of the effect of material properties on the structural design and performance of concrete. --
