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...

Perfobond Rib Connectors for Composite Beams
In this paper, the influence of concrete strength, transverse reinforcement and concrete dowels on the capacity of perfobond rib shear connectors is examined. Perfobond rib connector is...

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 Behaviour of Reinforced Concrete Beams Manufactured with Side Profile Sheets
The paper describes in qualitative terms the fundamental principles that control the behaviour of a completely new form of construction in which reinforced concrete beams are constructed...

Concrete Pipe for Sanitary Sewers Corrosion Protection Update
Significant advances have been made in the last decade in the area of sanitary sewer design techniques. Some of the most important advances have been in the prediction and prevention of...

Structural Design on Ductile Iron Pipe
The thickness class designation for Ductile Iron pipe has been changed to a pressure class designation in the 1991 revision of the C150/A21.50 ANSI standard. However, the same conservative...

Estimation of Reliability Parameters for Rehabilitation of Pipelines
This paper presents fundamental principles of estimating statistical characteristics of the elements of urban underground infrastructure networks, which provides a basis of statistical...

Evaluation of a Proprietary Tape Coating Alternative for the 157 Mile Ivie Pipeline
A two part evaluation of alternative protective coating systems for the 157 mile Ivie pipeline was made. In Part I, an evaluation was made on the suitability of a proprietary tape coating...

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...

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...

New Road Safety Initiatives in New Zealand
A considerable number of initiatives have been taken in New Zealand recently to keep pressure on the downward trend in road crashes and casualties. These have included government legislation...

Road Safety Audit: Prevention is Better Than Cure
Over the past two decades, the emphasis in road safety engineering has been on crash reduction through the development of remedial measures at high frequency sites. Road and traffic authorities...

Potential of Vegetable Oil as a Transportation Fuel
The esters of vegetable oils (Biodiesel) have potential as direct replacements for diesel fuel in compression ignition engines. This paper discusses fuel properties, short and long term...

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...

Seeing the Future: Changing Highway Engineering Practice Over the Next 10 Years
The computer age is here, and the more a highway engineer knows about computers, the better. This really symbolizes the direction highway engineers are headed - into a high-tech world...

Modified Graphite Reference Electrodes
The primary aim of this research was to investigate the feasibility of developing an improved, more reproducible, reversible, and highly voltage invariant graphite reference half cell...
