Abstract: A small degree of uncertainty has been observed in determining the significance of thermal loads when designing the superstructure of a horizontally curved steel bridge. This investigation focuses research on a three-span ...

Abstract: Bridges constructed with adjacent precast concrete box beams have been in service for many years. A recurring problem with this type of bridge is cracking in the longitudinal joints between adjacent beams. Many research ...

Abstract: The numbers and sizes of permitted vehicles that consist of at least four wheel lines have been increasingly crossing on highways and bridges. For safety purposes, it is necessary to understand how those truck loads are ...

Abstract: This paper discusses the effect of agricultural live-loads on lateral load distribution characteristics of girder bridges on rural roadways in the United States. In this study, load distribution factors for bridges subjected ...

Abstract: This paper presents the development of a universal model for predicting cyclic aerodynamic loads originating from buffeting, self-excited, and vortex shedding on a slender support structure in the time domain that can be ...

Abstract: The load rating factor is a measurement used to describe the load carrying capacity of a bridge, issue permits to heavy trucks, and determine load postings on bridges. The Bridge Engineering Center (BEC) at Iowa State ...

Abstract: Corrosion is important in the design, maintenance, and preservation of bridge steel pile foundation systems. It is an inevitable phenomenon when steel is exposed to the environment, as metals tend to return to their lower ...

Abstract: With slide-in bridge construction, the bridge superstructure is constructed off the final alignment and then slid laterally from the temporary worksite onto the in-place substructure. Once the sliding is completed, a closure ...
