Title: Ambient Thermal Stresses in Circular
Prestressed Concrete Tanks
Author(s): M. J. N. Priestley
Publication: Journal Proceedings
Appears on pages(s): 553-560

Abstract:Stresses induced in circular tanks.by daily variation in ambient conditions are investigated. Transient heat flow analyses are used to show that temperature gradients exceeding 30 C (54 F) can exist through the wall thickness if the effects of solar radiation are considered. The influence of various parameters on the thermal response is investigated. It is shown that tensile stresses as high as 6 Mpa (870 psi) can result from ambient thermal loading on the untracked section, and it is suggested that design should be based on a serviceability requirement rather than a limited tension stress as is current practice.
