SUGGESTIONS FOR REDUCING COSTS IN PRESTRESSED CONCRETE BRIDGES

THE OBJECTIVE OF THIS REPORT IS TO OFFER A NUMBER OF IDEAS FOR DECREASING THE COST OF PRESTRESSED CONCRETE BRIDGES. WITH THE EXCEPTION OF THE PROPOSAL FOR INCREASED TENSILE STRESSES, ALL OF THE WAYS CAN BE INCORPORATED WITHIN THE EXISTING 1961 AASHO STANDARD SPECIFICATIONS FOR HIGHWAY BRIDGES OR THE 1961 INTERIM SPECIFICATIONS. THE PRIMARY THEME HERE IS KEEP IT SIMPLE. ABOUT ONE-HALF OF THE SUGGESTIONS MUST BE INCORPORATED DURING THE INITIAL CONCEPTION OF THE BRIDGE DESIGN, BUT THE OTHER ONE-HALF DEALS WITH DETAILS. SEVERAL OF THE SCHEMES ADVANCED ARE ESPECIALLY WORTHWHILE WHERE HEADROOM IS CRITICAL. IF HEADROOM IS NOT CRITICAL, A DESIGN USING LARGE SECTIONS WITH WIDE SPACING IS SUGGESTED. /AUTHOR/
