Abstract: This paper presents the dynamic impact factors for horizontally curved steel box‐girder bridges. The dynamic impact is presented as a function of the span length and the first fundamental frequency. The results are discussed ...

Abstract: This paper presents a method for determining the dynamic impact factor of horizontally curved steel box‐girder bridges under vehicle loadings. The two‐dimensional planar grid analogy is used to model box bridges. The vehicle ...

Abstract: The objective of this paper is to determine the locations of the neutral axis and the effective flange widths for steel girder bridges that may be used in bridge design or, at least, in the bridge rating process. A study ...

Abstract: A study using field test results was conducted to determine the effect of live load for the slab-and-beam bridge structures. From the field testing of four existing bridge structures under the real truck loading, the live ...
