Live load distribution factors for multi-span girder bridges with plank decking subjected to farm vehicles
… provide simplified formulae to determine Live Load Distribution Factors (LLDFs) for highway bridges. The formulae for the AASHTO code-specified LLDFs have been developed, considering the effect of typical highway trucks. In addition to highway bridges, there are a large number of bridges …

Simplified live-load moment distribution factors for simple span slab on I-girder bridges
… identify and assess various methods of computing live load distribution factors and to use the results of laboratory and field tests to compare these methods. It is further a goal of this work to use these methods to perform a parametric study over a wide range of typical slab on steel I-girder …

Load Testing Deteriorated Spans of the Hampton Roads Bridge-Tunnel for Load Rating Recommendations
… Virginia coast has taken its toll on the main load carrying girders. Concrete spalling has exposed prestressing strands within the girders allowing corrosion to spread. Some of the more damaged girders have prestressing strands that have completely severed due to the extensive corrosion. The …

Distributed Fibre Optic Sensing to Assess Support Reactions and Behaviour of Composite Steel Bridges
… that involved beam, model bridge, and field load tests. Five steel beams were instrumented with fibre optic sensors and loaded in simply supported and continuous beam configurations. Disturbed regions in DFOS strain measurements were found to extend a distance equal to the depth of the …

Development of a Composite Concrete Bridge System for Short-to-Medium-Span Bridges
… of transverse bending due to concentrated wheel loads are investigated with respect to reflective cracking. Transverse bending moment are quantified and compared to transverse moment capacities provided by a combination of various cross-sectional shapes and transverse connections. A design …

Development of Innovative Hybrid Steel-Free Multi-Girder Bridge Deck System
… bridge deck system specimen under service load conditions exhibited negligible signs of creep and stress relaxation when subjected to repeated loading. The performance of the bridge deck specimen under various concentric and eccentric wheel load configurations led to live load distribution …
