A CONCEPT OF PREENGINEERED, PREFABRICATED, PRESTRESSED MODULAR AND MULTIMODULAR SEALING SYSTEMS FOR MODERN BRIDGES AND STRUCTURES

SINGLE-MODULE, MODULAR, AND MULTIMODULAR SEALING SYSTEMS APPEAR TO OFFER LONG-TERM, MAINTENANCE-FREE SOLUTIONS TO NEWLY DEVELOPING PROBLEMS AT BRIDGE JOINTS BROUGHT ABOUT BY NEW DESIGN SOPHISTICATION. THE NEED FOR ARMORED JOINTS AND THEIR DAMPING EFFECT TOGETHER WITH IMPROVED EMBEDMENT PRACTICES ARE DISCUSSED. UPWARD AND DOWNWARD VERTICAL FORCES, ROTATION, DEFLECTION, AND HORIZONTAL THRUST MOVEMENTS AND THEIR EFFECT ON SEAL SHAPES ARE ILLUSTRATED. THE TYPICAL BRIDGE-JOINT ENVIRONMENT CLEARLY DICTATES THE NEED FOR HEAVY-DUTY SEAL CONFIGURATIONS. WEB, TOP, AND SIDE MINIMUMS, DEPTH-TO-WIDTH RATIOS, AND PRESSURE-GENERATION REQUIREMENTS ARE PRESENTED AND ANALYZED. SOME METHODS OF RELIABLE DECK TEMPERATURE DETERMINATION AND ADJUSTMENT FOR TEMPERATURE ARE GIVEN. CREEP--SHRINK CALCULATIONS AND TESTING OF MODULAR AND MULTIMODULAR SYSTEMS ARE ILLUSTRATED. /AUTHOR/
