Researchers used advanced computer technology to analyze how continuous bridge deck slabs interact with steel I-girders. They considered factors like slab rigidity, girder spacing, and moving traffic loads to determine the effective strip width for evaluating negative slab moments. By developing empirical formulas, they found a way to accurately assess slab reinforcement needs for different bridge deck sizes.
