Abstract

The subject of this investigation is to evaluate the effect of the lateral confining pressure on the fatigue behaviour of concrete. The design and performance of the triaxial loading apparatus is described, the lateral pressure being applied hydrostatically while the longitudinal stress is applied mechanically through a balanced piston. The concrete strain was measured using calibrated internal strain gauges. The results of tests on 72 specimens, indicating the influence of the lateral confining pressure on the ultimate compressive strengi:h and strain of concrete and on the fatigue behaviour of concrete unde high (maximum) longitudinal compressive stress levels are presented. The results indicate that the fatigue life under lateral confining pressure is prolonged, depending on the maximum stress level of the fatigue loading.

The University of Calgary, located in the heart of Southern Alberta, both acknowledges and pays tribute to the traditional territories of the peoples of Treaty 7, which include the Blackfoot Confederacy (comprised of the Siksika, the Piikani, and the Kainai First Nations), the Tsuut’ina First Nation, and the Stoney Nakoda (including Chiniki, Bearspaw, and Goodstoney First Nations). The City of Calgary is also home to the Métis Nation of Alberta (Districts 5 and 6).

The University of Calgary is situated on land Northwest of where the Bow River meets the Elbow River, a site traditionally known as Moh’kins’tsis to the Blackfoot, Wîchîspa to the Stoney Nakoda, and Guts’ists’i to the Tsuut’ina. On this land and in this place we strive to learn together, walk together, and grow together “in a good way.”
