COMPUTER BRIDGE RATING SYSTEM

THE PROGRAMS ARE DESIGNED TO DETERMINE INVENTORY RATING, OPERATING RATING, AND POSTING LIMITS. THIS PROGRAM WILL RATE DECK SLABS OF REINFORCED AND PRESTRESSED CONCRETE; STRINGERS AND GIRDERS OF STEEL, REINFORCED CONCRETE, AND PRESTRESSED CONCRETE BOTH COMPOSITE AND NON-COMPOSITE; STEEL AND CONCRETE FLOOR BEAMS AND SIMPLE SPAN TRUSSES. INVENTORY AND OPERATING RATINGS ARE BASED ON EITHER THE STANDARD AASHO "H" OR "HS" VEHICLE. POSTING RATINGS ARE BASED ON THREE DIFFERENT VEHICLES WHICH ARE REPRESENTATIVE OF MAXIMUM LEGAL LOADS ALLOWED BY LAW. SLIDES ILLUSTRATE VEHICLES USED TO DETERMINE POSTING LIMITS; PROCEDURES USED IN RATING A BRIDGE; INPUT DATA OBTAINABLE DIRECTLY THROUGH THE PLANS; ITEMS REQUIRING MANUAL CALCULATION; INPUT SHEETS; TYPICAL OUTPUT SHEET; THE OUTPUT SHEET IDENTIFYING THE MOST CRITICAL MEMBER OF THE FLOOR SYSTEMS; THE OPERATING RATING SUMMARY; THE OUTPUT SHEET TITLED "SUMMARY OF RATING CALCULATIONS- STRUCTURE POSTING ANALYSIS". CONTROL CARDS REQUIRED FOR EACH BATCH ARE LISTED. THE SYSTEM IS DESIGNED FOR USE IN 2 STEPS. THE FIRST COBOL PROGRAM WILL SORT, EDIT AND STORE INPUT DATA. CORRECTIONS ARE MADE WITH ANOTHER RUN. A SECOND FORTRAN PROGRAM IS THEN EXECUTED TO COMPUTE THE BRIDGE RATING.
