Abstract: This study was initiated after the sliding plate expansion joints of Millard E. Tydings Memorial Bridge, a long-span truss bridge, failed prematurely just a few months after their initial installation. The study included ...

Abstract: Condition-ratings in bridges have been used by the Federal Highway Administration as a way to classify structural deficiencies and structures that are functionally obsolete. These ratings are determined by evaluating the ...

Abstract: The softened truss model theory applied to a prestressed concrete multiple cell box is developed in this study. In this theory, the concrete torsional problem is solved by combining equilibrium and compatibility conditions ...

Abstract: Keysville Road Bridge is an 1880 wrought-iron truss bridge listed on the U.S. National Register. The bridge is across Tom's Creek, located in Frederick County, Maryland. This 31.4-m-(103 ft)-long structure has an overall ...

Abstract: Optimal infrastructure development and expansion decision making requires taking into account contingent expansion decisions and underlying uncertainty, such as demand, during the planning period. Recent publications on ...

Abstract: The working stress, load factor and autostress methods are applied to the rating of composite and noncomposite steel beam and girder bridge structures. These three methods are developed and used to rate a series of 16 ...

Abstract: The integral collocation method (ICM) is used to analyze large deflected circular plates with clamped (radially held and not held) outer edge under uniform pressure. The ICM has been completely computerized with automatic ...

Abstract: A simple, easy-to-apply effective torsional constant for the rotational stiffness of a restrained open section was developed. This effective torsional constant takes both the pure torsion and the warping torsion into ...

Abstract: This paper reports the bridge damage in the Chi Chi earthquake. Damage to bridge structures may occur in the superstructure, the substructure, or the approaches. Typical types of damage are discussed and illustrated in ...

Abstract: The long-term behavior of long-span prestressed concrete continuous rigid-frame bridges is significantly sensitive to creep and shrinkage. Therefore, it is important to accurately estimate creep and shrinkage effects. This ...
