Strength Deterioration Behavior of Concrete-Filled Steel Tubular Beam-Columns
Cantilever beam-columns of steel square hollow section with or without filled-concrete were tested under constant axial load and alternately repeated horizontal load to investigate the...
Force Transfer in Composite Columns
The force transfer from steel to concrete without mechanical transfer devices in composite columns at points of load introduction is studied. A mechanism of force transfer and the factors...
New Steel Beam to Composite Column Connection Detail
Composite columns consisting of hollow steel tubes filled with high strength concrete with compressive strength exceeding 10000 psi (69 MPa) are being used in high-rise buildings. Connecting...
Behavior of Unbonded Braces Restrained by Reinforced Concrete and FRP
A new composite steel brace called an unbonded brace (UB) is proposed to enhance the capacity of a steel brace to carry a compressive load of almost up to the yield strength of the steel...
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...
Effects of Connections on Composite Frames
This paper summarizes the preliminary findings from an experimental and theoretical study of the influence of composite connections on frame behaviour. The first part of the work included...
The Ivie Pipeline Delivering Water to West Texas
The Ivie Pipeline is a $76,000,000 - 156-mile long water pipeline being constructed in West Texas. This paper describes highlights of the planning, design, and construction phase....
Reinforced and Prestressed Concrete Pressure Pipe Diagnosis
Prestressed and reinforced concrete steel cylinder pipes are used for transmission mains, water intake lines, sewers force mains. Many collapses caused by the steel cylinder attack were...
Gas Pipeline Fitness-for-Service Investigation
A delta reclamation district's plan to add significant fill on their levee caused great concern for the integrity of a critical PG&E 22-inch (559 mm) gas transmission line which...
Pipelines Crossing Highways and Railroads by Tunneling
When new pipeline construction requires the crossing of highways and railroads, a pipeline is generally installed in pipe or tunnel linear plate encasement which has been installed by...
Analysis and Design of Direct Burial Sections of San Diego County Water Authority's Pipeline 4 Extension
The pipeline 4 extension is one of the San Diego County Water Authority's Phase I projects that will run for about 13 miles. Majority of this new pipeline will be 96 inch in steel and...
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...
BMS Modelling of Bridge Stock Performance
A computer-based Bridge Management System, BMS, was designed in Finland by the Finnish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...
Level of Service in Bridge Management Systems
The Federal Highway Administration's Sufficiency Rating is not adequate for evaluating bridges. It ignores fundamental bridge characteristics and is far too subjective. The Level of Service...
Bridge Management System Implemented in Thailand
The latest ten years' economic growth in Thailand and the associated increase in roadway and railway traffic has exposed the existing bridge structures as bottlenecks of these transportation...
A GIS-Based Rail Infrastructure Management System
Computer-based models and analytical techniques are powerful components of infrastructure management systems. However, the availability of data sets significantly affects the usefulness...
Coordination of ISTEA?1991 Management Systems
Following the successful development and implementation of pavement management concepts, the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) contains the provision that...
Controlling Corrosion in Bridge Structures
The overall objectives of the Structures Research Area of the Strategic Highway Research Program (SHRP) were to provide methods to protect chloride-contaminated concrete components against...
Electrochemical Treatment and Protection: Lessons Learned
Corrosion is recognized today as one of the major contributors to the deterioration of steel reinforced concrete structures. Two electrochemical techniques, chloride removal and cathodic...
Concrete Bridge Protection Repair & Rehabilitation
A methodology for the selection of cost effective solution(s) to the protection, repair, and rehabilitation of concrete bridges in chloride-laden environments is presented. The methodology...
