Economics of Post-tensioned Circular Concrete Tanks in South Africa

When is strand cheaper than rebar as circumferential reinforcement in circular concrete tanks? In circular tanks smaller than a certain critical size, hoop tension is sufficiently low for effective crack-control by only moderate rebar. In this size range post-tensioning is uneconomical, but with increasing size, a critical point is reached where post-tensioning becomes the economic choice. So [...]
