Structural and Economic Benefits of Precast/Prestressed Concrete Construction

摘要

This article presents advantages in the application of precast/prestressed cocrete in structural frames. Using pretensioned concrete components in conjunction with a composite cast - in - place concrete topping creates a lighter structural system than an all - cast - in - place structure. Shoring pretensioned beams and slabs before adding the composite topping can reduce member size even further.
