Model Bridge Study. Volume 4. Service Load, Overload, and Maximum Load Testing.

摘要

The Federal Highway Administration (FHWA) and the American Iron and Steel Institute (AISI) are jointly conducting a research study at FHWA's structures laboratory entitled 'Structural Modeling for Autostress by Loading Through a Precast Deck.' The bridge under investigation is a two-span continuous three steel girder 0.4 scale model approximately 113 ft (34.44 m) long. The deck, consisting of transversely pretensioned panels, post-tensioned longitudinally, is composite with the steel girders. This report summarizes the results of a small-scale component test conducted to verify the moment rotation characteristics of the girder section proposed for use in the model bridge. This volume is the fourth in a series.
