RISOptimizing Horizontally Curved, Steel Bridge, Cross-Frame Arrangements to Enhance Construction Performance
Publisher: American Society of Civil Engineers
Abstract: Unlike straight bridges where cross frames and diaphragms are considered secondary members that predominantly stabilize the compression zones of noncomposite girders during construction, the interaction of bending and ...
Reinforced Concrete Bridge Column Multihazard Performance: A Computational Tool to Assess Response to Vehicle Impact, Air Blast, and Fire
Publisher: ASCE
Abstract: Pier columns, as primary bridge supports, are vulnerable to extreme loading demands resulting from fire, vehicle collisions, and blasts. The combined effects of these demands may cause significant strength reduction, ...
Effect of Temporary Shoring Location on Horizontally Curved Steel I-Girder Bridges during Construction
Publisher: American Society of Civil Engineers
Abstract: Temporary shoring supports are used in construction of horizontally curved bridges to help ensure that the final constructed geometry is maintained by mitigating excessive girder deformations. Limited guidance currently ...
Nonlinear Seismic Response and Parametric Examination of Horizontally Curved Steel Bridges Using 3D Computational Models
Publisher: American Society of Civil Engineers
Abstract: The seismic behavior of horizontally curved steel bridges is more complex than straight bridges because of their curvature and other parameters. Studies that attempt to develop methods to efficiently predict their seismic ...

The Temperature and Depth Accuracy of Sippican T-5 XBTs
Publisher: American Meteorological Society
Abstract: Thirty-four near-simultaneous pairs of CTD and Sippican model T-5 XBT profiles were obtained during an experiment in the Sargasso Sea during the summer of 1991. The data were analyzed to assess the temperature and fall-rate ...
Evaluation of the Sparton Tight-Tolerance AXBT
Publisher: American Meteorological Society
Abstract: Forty-six near-simultaneous pairs of conductivity-temperature-depth (CTD) and Sparton ?tight tolerance? air expendable bathythermograph (AXBT) temperature profiles were obtained in summer 1991 from a location in the Sargasso ...
Historical Perspective on Horizontally Curved I Girder Bridge Design in the United States
Publisher: American Society of Civil Engineers
Abstract: This paper provides a historical overview of the development of horizontally curved steel I girder bridge design specifications in the United States. The background to the development of curved I girder design and analysis ...
Evaluation of Live-Load Lateral Flange Bending Distribution for a Horizontally Curved I-Girder Bridge
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on levels of live-load lateral bending moment (bimoment) distribution in a horizontally curved steel I-girder bridge. Work centered primarily on the examination of (1) data from field testing of an ...
Examination of Level of Analysis Accuracy for Curved I-Girder Bridges through Comparisons to Field Data
Publisher: American Society of Civil Engineers
Abstract: To evaluate the accuracy of different levels of analysis used to predict horizontally curved steel I-girder bridge response, a field test was performed on a three-span structure. Collected strain data were reduced to ...
