PRECAST BRIDGE PIERS OFFER OPTION TO DESIGNERS

The advantages are outlined of using precast concrete elements to construct the ordinary, little-noticed bridge bents most typical of beam-type highway structures. A substantial reduction in the amount of concrete used as "filler" in the core of the column can be achieved at the cost of only a small reduction in structural capacity and moment of intertia, which can be offset by increasing the diameter of the column a small amount. A Significant amount of time can be saved in the field. For stream crossings, for example, where seasonal high water occurs, the construction "window" becomes a critical factor in timely completion. Other precast advantages are noted, and design considerations are reviewed. Basic elements of the construction approach are described.
