Thermal Cracking of the Cylindrical Tank under Construction. I: Case Study
Publication: Journal of Performance of Constructed Facilities
Volume 29, Issue 4
Abstract
The authors present their own experimental studies, which include research on a reinforced-concrete cylindrical tank with a nominal unit capacity of , located in the sewage treatment plant in Krakow, Poland. The wall is monolithically connected to the foundation ring and was concreted in two stages: every second segment. This tank is classified among semimassive structures, which, owing to its volume and geometry, has an ability to store up a greater amount of released heat during the hardening process. At the stage of tank erection, because of cracks, numerous cases of leakage through the tank wall appeared. The measurement of longitudinal concrete deformation and crack development, together with the crack widths in selected segments, are presented. Moreover, the measurement of strains and crack-width propagation in vertical construction joints among three selected segments are discussed. The research presented provides information about the real behavior of such a structure under construction. In the subsequent paper (Part II), the results from experimental studies will be compared with the results obtained from an advanced numerical model.
