Uncertainty of Bridge Scour Estimates
Pier scour is the erosion of a streambed in the vicinity of bridge pier foundations. In this paper, fuzzy regression is used to develop two pier scour models, one based on crisp laboratory...
Field Examination of a Distribution System Water Quality Model
In the aftermath of the Safe Drinking Water Act (SDWA) of 1974, numerous models have been established to assess the quality of water and simulate its deterioration in distribution systems....
Evaluation of Historical Scour at Selected Stream Crossings in Indiana
Geophysical data were collected by means of ground-penetrating radar and tuned transducer systems to estimate the historical scour at ten bridges in Indiana. These geophysical data were...
Shale Scour at BNRR Yellowstone River Bridge, MT
Both the Burlington Northern Railroad and Montana Department of Transportation bridges across the Yellowstone river just south of Laurel, Montana, are founded on spread footings placed...
Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...
Two Full-Scale Tests of Class 3 Composite Beams
This paper presents two tests of continuous composite beams comprising two 7.5 m spans and two concentrated loads close to the intermediate support. Although the cross-sections on the...
Shear Connection in Composite Beams
This paper considers the influence of the shape of the deck profile on the shear connection of composite beams. It was found that the existing strength reduction factor can be unconservative...
Connection of Grouted Tubular Insert Piles to Soil
Force transfer between offshore production jackets and tubular piles is effected by weld bead shear connectors, acting within the grout filled annulus between the piles and pile sleeves...
The Connecting Method of Steel and Concrete Using Long Deformed Bar Studs
A new welding technique for long horizontal studs of 19 mm and 22 mm diameters was established. The transmission of shearing and bending forces was evaluated using large model tests. Actual...
Design of Composite Slabs for Vertical Shear
Three major modes of failure should be considered in the design of the positive moment regions of composite slabs incorporating profiled steel sheeting, viz.: flexure, longitudinal slip...
Seismic Performance and Composite Action of Older Structures
A study into the seismic performance of older steel structures is described. A review is made of the types of steel building construction completed during the period of interest, and the...
Development of Composite Slab with Truss-Typed Shear Connectors
This paper describes the results of the test on a steel-concrete composite slab with truss-typed shear connectors. This composite slab was recently developed. A series of tests were conducted...
Full-scale Tests on Composite Connections
Tests have been carried out on eight full-scale composite connections in which the columns were manufactured of concrete-filled steel circular hollow sections (CHS). The connections were...
Influence on Steel Deck on Composite Beam Strength
Results of a recent study were described in which 7 push-out tests and 4 composite beam tests were conducted. The results were consistent with other recent studies reported in the literature,...
Composite Beams with Headed Studs in Narrow Ribbed Metal Deck
This paper presents the results of sixteen push-out tests conducted to study the behavior of headed stud connectors in composite beams with narrow ribbed metal deck placed parallel to...
Steel Panel Encased R.C. Composite Shear Walls
In order to make clear the fundamental resisting mechanisms of composite shear walls, tests are carried out on the composite unit rigid frames with various infilled shear walls. Composite...
Pipeline Leak Detection Based on Mass Balance
Current technologies in Supervisory Control and Data Acquisition (SCADA) systems enable pipeline leak detection to be carried out in real time by software-based methods. This paper discusses...
Database for Pipeline Bridges in North America
Work began in 1985 at Wayne State University on a research study of pipeline suspension bridges. This effort, which was funded by ANR Pipeline Company of Detroit, Michigan, investigated...
Microtunneling of Vitrified Clay Pipe in the United States
Vitrified clay pipe (VCP) has been used for centuries to convey waste water away for cities. In Europe and Japan, VCP has been used in the microtunnelling process for longer than 10 years....
Field Testing of Advanced Maintenance Data Acquisition Technologies in Three State DOTs
Field testing and evaluation of advanced data acquisition technology in Maryland, Connecticut and Arizona showed the potential for state highway agencies to improve existing procedures...
