Response of Continuous Steel I-Girder Bridges Subject to Temperature Variation
… of the superstructure in continuous slab-on-girder bridges must be freely permitted to avoid potential adverse behavior due to the development of thermal forces. The use of fixed and guided bearings can introduce a significant amount of restraint against thermal deformation that, if not …

Effect of Thermal Loading on the Performance of Horizontally Curved I-Girder Bridges
… design alternative to the traditional straight girder or chorded bridges as they can provide the designer a more cost effective solution to complicated geometrical limitations or site irregularities. However, the volume of research and knowledge on the behavior of curved bridges is lacking …

Seismic performance of an I-girder to inverted-T bent cap bridge connection
… and overall moment capacity of precast I-girder to inverted-T bent cap bridge connections for seismic applications. The current design practice, as outlined by Caltrans' Seismic Design Criteria, assumes that the connection between the precast I-girders and the inverted-T bent cap will …

Evaluation of superstructure response and load distribution in skewed steel I-girder bridges
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

Simplified live-load moment distribution factors for simple span slab on I-girder bridges
… over a wide range of typical slab on steel I-girder bridges to assess the accuracy of both the AASHTO Standard and AASHTO LRFD specifications and to propose an empirical model that correlates better with the analytical results within the range of parameters that are to be studied.;These …

Carbon Fiber Reinforced Polymer Repairs of Impact-Damaged Prestressed I-Girders
… capacity of impact-damaged prestressed concrete girders. The number of severed prestressing strands and the amount of CFRP repair material applied are varied to create a large repair matrix. The ultimate moment capacity was calculated using the program XTRACT. Capacities were also evaluated using …

Slab-on-girder prestressed concrete bridges: linear and nonlinear finite element analysis and experimental load tests
… a transverse stiffener, which is placed between girders in order to maintain section geometry”, (AASHTO, 2002). Intermediate diaphragms, usually placed at the midspan or third points of a bridge, are thought to contribute to the overall distribution of live loads in bridges. Cast-in-place …

Repair of damaged end regions of prestressed concrete girders using fiber reinforced polymer composite materials
… concrete beams. One problem afflicting bridge girders in cold climates is the deterioration of the girder ends due to deicing salt exposure, thus reducing their shear strength. This thesis presents the results of the beginning stages of an Illinois Department of Transportation (IDOT) sponsored …

Behaviour and modelling of the inelastic response of concrete and steel-concrete infrastructures subjected to low-cycle fatigue
… of the Hot-rolled (HRS) steel to manufacture I-girder beams has become an innovation in civil infrastructures in Europe, as much as the use of transversal concrete cross-beams (CCBs) to connect spans. With reference to the hazard selected, a suitable case study was chosen. With the aim of …
