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...
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...
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...
Townsite Lateral-Stage 2 Belle Fourche Unit - Cheyenne Division Concrete: Pipe with Dumped Bedding and Embedment
In 1933, M. G. Spangler presented three bedding configurations and the concept of a bedding factor to relate the supporting strength of buried concrete pipe to the strength obtained in...
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...
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...
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...
Standard Installations: A Synopsis of the ASCE Standard Practice for Direct Design of Buried Precast Concrete Pipe
In 1970, the American Concrete Pipe Association (ACPA) began a long range research program which focused on the behavior of buried concrete pipe. The research resulted in the comprehensive...
Predictive Model Aids in Development of Systemwide Rehabilitation Program
Effective management of urban infrastructure requires accurate assessment of system-wide condition. Working with the City of San Jose, CH2M HILL has developed a computer model to provide...
Proactive Odor Control Using Computer Modeling
The City of Los Angeles (City) is currently designing the East Central Interceptor Sewer (ECIS) as a major relief sewer. The pipeline will convey wastewater flows that originate upstream...
Innovations in the Development and Expansion of Intermodal Facilities
The intermodal industry is a dynamic one, with a long history which has undergone profound change since the introduction of containerization only 30 years ago. Today, change continues...

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...
The Transrapid EMS Maglev System
The Transrapid 300 mph (500 km/hr) magnetically levitated transportation system is ready for revenue application. The maglev system uses contactless electromagnetic suspension and three...
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...
Validation of SHRP Performance Graded Binder Specifications Using Field Simulation Testing Equipment
The Strategic Highway Research Program (SHRP) was initiated to improve the effectiveness of laboratory test methods in predicting field performance. European highway agencies are using...
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...
