Maximum Length of Integral Bridges Based on the Performance of Steel H-Piles at the Abutments

Analytical equations are developed to estimate maximum length of integral bridges based on the lateral displacement capacity of steel-H piles under the effect of cyclic thermal variations. For this purpose, a low-cycle fatigue damage model is employed to determine the maximum cyclic curvatures such piles can sustain. The determined cyclic curvature limits are used in static pushover analyses of two steel H-piles driven in soil to obtain the maximum thermal-induced cyclic lateral displacements such piles can accommodate. Using the pushover analyses results, the maximum length limits for integral bridges subjected to cyclic thermal variations are formulated as a function of pile's properties, soil type and stiffness.
