Abstract: Two reinforced concrete bridge bents were subjected to large, transverse displacements. The bents contained detailing deficiencies typical of the 1960s, including minimal transverse reinforcement, short reinforcing splices, ...

Abstract: Cyclic, transverse loads were applied to the bents of a three-span reinforced concrete bridge. At a load equal to 45% of the bridge's weight, the bent drift ratio was 0.5%. The bridge's high stiffness was attributed to its ...

Abstract: For earthquake‐resistant design of reinforced concrete structures, the shear force for frame elements is established on the basis of the proportions and flexural strength of the element according to the American Concrete ...

Abstract: A two-dimensional algorithm has been developed to determine the locations and sizes of steel bars in reinforced concrete members. This algorithm uses magnetostatic relationships to relate measured distortions in the magnetic ...

Abstract: The effects of non-uniform excitation on short bridges were studied by computing the response of an idealized bridge to a suite of earthquake ground motions. The ground motions for each support were developed from seven ...

Abstract: Nondestructive evaluation plays an important role in the assessment of the nation's infrastructure. The evaluation methods for reinforced and prestressed concrete facilities can become more reliable if the methods incorporate ...

Abstract: A practical model has been developed to predict, for a given level of lateral deformation, the likelihood that longitudinal bars in a reinforced concrete column will have begun to buckle. Three relationships linking plastic ...

Abstract: The performance of tall reinforced concrete core building archetypes in Seattle, Washington, was evaluated for 30 simulated scenarios of a magnitude 9 (M9) Cascadia subduction zone interface earthquake. Compared with typical ...

Abstract: A reinforced concrete, box-girder bridge will collapse during an earthquake if the relative displacement between adjacent frames at an in-span expansion joint exceeds the available seat width. To identify factors that most ...

Abstract: This paper presents an evaluation of flexural live-load distribution factors for a series of three-span prestressed concrete girder bridges. The response of one bridge, measured during a static live-load test, was used to ...
