Available in PDF, EPUB and Kindle. Book excerpt: The use of horizontally curved composite bridges in the interchange facilities of modern highway systems has become increasingly popular for economic as well as for aesthetic considerations. Cellular steel sections composite with a concrete deck are quite suitable in resisting torsional and warping effects induced by highway curvature. However, this type of structure has inherently created design problems for the designer in estimating the level of dynamic response when subjected to moving vehicles, wind, or seismic conditions. This paper presents a summary of an estensive parametric study, using the finite-element method, in which 120 simply supported, curved composite bridge prototypes are analyzed to evaluate their natural frequencies and mode shapes. The parameters considered in the study are end-diaphragm thickness, cross-bracing system, aspect ratio, span-to-depth ratio, degree of curvature, number of lanes, and number of cells. Results from tests on four 1/12 linear-scale simply supported composite three-cell bridge models of different curvatures are used to substantiate the analytical modelling. The stipulation made in bridge codes for treating a curved bridge as a straight one is examined. Based on the data generated from the parametric study, expressions for the first flexural frequency and hence the dynamic load allowance are deduced. Recommendations for enhancing the torsional resistance to dynamic forces on curved bridges are presented. Two design examples are illustrated.

Available in PDF, EPUB and Kindle. Book excerpt: The use of cellular-shaped cross sections for highway bridges, especially on curved alignments, is an economical solution because of the high flexural and torsional strength of such sections. This paper summarizes the dynamic characteristics of curved composite multi-cell (contiguous boxes) bridges, continuous over two and three spans. An extensive parametric study, using the finite-element method, was conducted to evaluate the key parameters that may affect the natural frequencies and the corresponding mode shapes for this type of bridge. These parameters are end-diaphragm thickness, number of cross-bracings, aspect ratio, span-to-depth ratio, degree of curvature, number of cells, and span-to-span ratio. The effect of cracking of the concrete deck slab in the vicinity of interior supports is also investigated, Results obtained from tests on 1/12 scale two-span continuous curved composite three-cell bridge model are used to substantiate the analytical modelling. Based on the date generated from the parametric study, empirical formulas for the dominant frequency are deduced. An illustrated design example is presented. A study is also conducted to determine the dynamic deflections caused by a moving truck over the bridge with a view to improve human discomfort and perception to vibration.
