Semi-Rigid Joint Action in Composite Frames: Numerical Analysis and Design Criteria
The paper focusses on the analysis of semi-rigid composite frames, reporting mainly on the results of a research study which combines the experimental and theoretical approaches. Attention...

Columns of Concrete-Filled Rectangular Hollow Sections
Concrete-filled hollow sections are normally used as columns in multi-storey buildings and also in similar structures. Such columns may be filled with plain concrete with no need for any...

Recent Developments in Composite Bridges
Composite steel and concrete bridges are becoming increasingly popular, in particular for short and medium spans. This renewed interest is due first of all to the great freedom for creativity...

Numerical Analysis of Composite Slab Behavior
A new calculation procedure is described which provides an alternative to full-scale testing for composite slabs with ribbed decking used in buildings. This procedure consists of combining...

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...

Self-Cleaning Wet Wells: Definition and Design
Design guidelines for self-cleaning wet wells with variable speed pumps are given and the progress of research at Montana State University and ENSR Consulting and Engineering concerning...

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...

Selection and use of Pipeline Leak Detection Methods for Liability Management into the 21st Century
Pipeline leak detection systems have been in use for many years on all types of pipelines with various products being transported. Pipeline owners and operators are subject to stringent...

Analysis of Pavement-Pipeline Systems After Cut Restoration
The placement of utility pipes normally necessitates many cuts and fills of the existing pavements. Integrity of pipeline and compatible performance of cut restoration and original pavement...

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...

Chemical Resistance of Thermosetting Resins Used for Cured-in-Place Pipe
This paper summarizes the chemistry, short term physical properties, and long term chemical resistance for representative epoxy vinyl ester, epoxy, and polyester resins that are currently...

The Design and Development of A Road/Rail Power Unit
The road/rail power unit was designed and developed by Saskatchewan Highways and Transportation to provide low cost motive power on low-density disconnected rail lines. The power unit...

Innovative Contracting Practices in Developing an Advanced Freeway Management System
Throughout the nation, many public agencies have determined to incorporate time saving and cost effective project innovations while maintaining and upgrading project quality. One possible...

Long-Term Pavement Performance Program for Years 1992-1997: A Strategic Plan
The Federal Highway Administration (FHWA) began operational management of the Strategic Highway Research Program's (SHRP) Long-Term Pavement Performance (LTPP) program on July 1, 1992....

Steps to a Mix Design Solution for Better Asphalt
Three primary products will be delivered at completion of the Asphalt Research Program of the Strategic Highway Research Program, a performance based asphalt binder specification, a performance...

How SHRP Reliably Predicts Pavement Performance
One of the important results of the SHRP Asphalt Research Program was to develop a comprehensive pavement performance model that reliably predicts rutting, fatigue cracking and thermal...

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...

Future Improvements for Design of Flexible Pavement Structures
The first set of data analyses on the National Pavement Data Base (NPDB) derived from the Long-Term Pavement Performance (LTPP) activities have been completed. The results from sensitivity...
