BRIDGES WHERE THE DECK SLABS AND THE MAIN GIRDERS WORK TOGETHER TO RESIST LOADS ARE CALLED COMPOSITE GIRDER BRIDGES, AND BRIDGES DESIGNED TO RESIST LOADS WITH THE MAIN GIRDERS ONLY ARE CALLED NON-COMPOSITE GIRDER BRIDGES.
A LIGHT STRUCTURE, WHICH IMPOSES SMALLER LOADS ON PIERS AND FOUNDATIONS, ALLOWING FOR ECONOMY.
A STEEL MAIN STRUCTURE THAT IS MUCH EASIER TO ERECT IF COMPARED TO THE CONSTRUCTION OF A CONCRETE GIRDER
A CONCRETE SLAB, WHICH IS CHEAPER AND EASIER TO BUILD THAN A STEEL ORTHOTROPIC DECK, AND ALSO PRESENTS TWO OTHER ADVANTAGES:
A HIGHER MASS, WHICH INDUCES FEWER VIBRATIONS, NOISE, AND DYNAMIC LOADS ON THE SUPPORTING STRUCTURE
A TOP SURFACE THAT ALLOWS FOR EASY PAVING WITH TRADITIONAL METHODS, WHILE WEAK POINTS OF THE ORTHOTROPIC DECK CONSISTS OF THE DIFFICULTY OF REALIZING A STRONG BINDING, THE DELICATE EXECUTION, AND SOME CONCERN ABOUT DURABILITY OF ITS PAVING
