A Procedure for the Determination of Design Requirements in Continuous Skewed Slab Bridge Decks

摘要

The report presents a method for determining the maximum and minimum moments in a three-span continuous skewed slab bridge deck under single vehicle loading. Influence coefficients for regularly-spaced points of load application, which were developed in a previous study, are used for determining the moments at specified node points under a particular loading. A computer program for use with the IBM 1410 was developed to carry out the procedure in combination with a library of influence coefficient sets for a variety of symmetrical three-span structures of different angles of skew and width to center-span ratios for primary input. A value of 0.8 for end to center-span ratio is assumed for all structures. The angle of transverse reinforcement and the vehicle weight and axle spacing are treated as variables. (Author)
