RISInspection of Luling Bridge Cable Stays: Case Study
Publisher: American Society of Civil Engineers
Abstract: Most cable-stayed bridges in the United States have been built in the last 30 years. As the number of existing cable-stayed bridges increase, one problem continues to arise—how to inspect the cable stays for corrosion and ...
Providing Lead Role in Work‐Force Diversity
Publisher: American Society of Civil Engineers
Abstract: This paper describes the efforts of the Northwest District of the Minnesota Department of Transportation employees to implement a fair work environment culture that stresses increased employment of Indians and placement ...
Measuring Ozone by Indigo Method: Interference of Suspended Material
Publisher: American Society of Civil Engineers
Abstract: The indigo trisulfonate method has been proposed in the current edition of
A System Identification Technique Using Bias Current Perturbation for Determining the Effective Rotor Origin of Active Magnetic Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Locating the effective rotor origin of an active magnetic bearing (AMB) is an important step toward accurate characterization of the bearing air gaps for field tuning, performance analyses, and ...
Location and Depth of Pervious Concrete Clogging Material before and after Void Maintenance with Common Municipal Utility Vehicles
Publisher: American Society of Civil Engineers
Abstract: In practice, it has been observed that the method of pervious concrete void maintenance depends on which machines or vehicles the owners have available. This research compares the abilities of three common municipal utility ...
Vortex Stability in a Large-Scale Internal Wave Shear
Publisher: American Meteorological Society
Abstract: he effect of a large-scale internal wave on a multipolar compound vortex was simulated numerically using a 3D Boussinesq pseudospectral model. A suite of simulations tested the effect of a background internal wave of various ...
Upscale Energy Transfer by the Vortical Mode and Internal Waves
Publisher: American Meteorological Society
Abstract: iapycnal mixing in the ocean is sporadic yet ubiquitous, leading to patches of mixing on a variety of scales. The adjustment of such mixed patches can lead to the formation of vortices and other small-scale geostrophic ...
Improved Longitudinal Joint Details in Decked Bulb Tees for Accelerated Bridge Construction: Concept Development
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on an investigation of improved continuous longitudinal joint details for decked precast prestressed concrete girder bridge systems. Precast concrete girders with an integral deck that is cast and ...
Tower of Montecchio Stress Analysis of Southeast Wall
Publisher: American Society of Civil Engineers
Abstract: A stress analysis is performed herein on the southeast wall of the tower in the medieval fortress Montecchio, which is situated in Tuscany, Italy. The analysis is performed by the finite-element method, and the effects of ...
Screening Tool to Assess Adequacy of Bridge Timber Pile Bents during Extreme Scour Events
Publisher: American Society of Civil Engineers
Abstract: Timber substructure bridges supported by three, four, or five piles were commonly used in Alabama in the past for secondary and county highway bridges. Because of the large number of such bridges in the state, the Alabama ...
