Concrete Buildings — A Mile High

Abstract

The number and height of tall buildings in general and of tall concrete buildings in particular has increased dramatically in the last 40 years. In the last 25 years there have been dramatic advancements in the technology of construction of tall concrete buildings with the advent of new forming systems such as slip-forming, flying forms, gang-forms, and so forth. Also, the development of ultimate strength design, the development of structural lightweight concrete, the development of high strength concrete, the use of admixtures (in particular superplasticizers), and concrete pumping techniques have given concrete a great boost for tall structures.
