Switching to high-strength concrete allowed a precaster to simplify column designs and save money on a 22-story condominium project. The original design called for precast elements using 5000-psi concrete. Switching from conventional to high-strength concrete permitted a 33 percent reduction in precast column size. In addition, fewer longitudinal bars and fewer column ties were needed. Using high-strength concrete also allowed a major change in the type of precast elements used. Because the redesigned columns were smaller and lighter, two columns and a beam could be combined into a monolithically cast bent. This simplified the design and construction of the precast shear walls.
