Abstract
Formulas are proposed for computing the maximum deflection and maximum a negative edge-moment occurring in a steel-grid highway bridge floor under wheel loads. Separate equations are given for concrete-filled steel-grid floors and open-grid steel floors, respectively. These equations take into account the basic anisotropy of such floors as a variable and are designed to fit the data tabulated by K. C. Kuo who completely analyzed the problem. For completeness, the results of Mr. Kuo's analysis are summarized, including the formulas he proposed for computing maximum positive bending moments in such floors. Graphs of the deflection and moment coefficients over the required ranges of span and the anisotropy variable are included.
