DOWNLOAD EBOOKResearch 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.

DOWNLOAD EBOOKThe main purpose of the research project reported herein was to determine the stress-strain behavior, ultimate strength, and failure mechanism of high-strength concrete subjected to biaxial compression. Model concrete plate specimens, composed of nine aggregate discs embedded in a mortar matrix, were used. Three different strength and elastic properties were used in order to determine the effects of material properties on the behavior of high-strength concrete subjected to biaxial compression. The plate specimens were tested using four biaxial stress ratios: 0 (uniaxial), 02, 0.5, and 1.0. Deformations in both the major and minor principal directions were measured using Direct Current Differential Transducers. Stress-Strain characteristics, discontinuity, ultimate strength and failure modes in biaxial compression as a function of materials properties are discussed.

DOWNLOAD EBOOKMasters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

DOWNLOAD EBOOKResearch at The University of Texas has been conducted to determine the properties and behavior of plain, high-strength concrete subjected to biaxial-cyclic compression. Static and dynamic tests were performed on a total of 95 specimens which consisted of 5-in. square x 1/2-in. thick plates of concrete. Tests were performed in a biaxial test machine developed at The University of Texas. The primary variables studies were the maximum stress level, expressed as a percent of the uniaxial-static compressive strength, and the biaxial stress ration, expressed as the ratio of the vertical to horizontal stress. Other variables included the stress range and the effect of the moisture content in the material.
