Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...

Processed-Snow Foundation Design at the Summit of the Greenland Ice Cap
The design and construction of a processed-snow foundation berm for an elevated building located at the summit of the Greenland Ice Cap is described. Weather conditions and design provisions...

A Mechanistic Approach to Pavement Design for Nome Airport
The analysis of performance and design of the pavement structure for the North-South runway at Nome Airport is based on the mechanistic approach. In the mechanistic approach, calculated...

Treatment of Unstable Foundation Areas in Alaska's Pavement Management System
In the State of Alaska Department of Transportation and Public Facilities Pavement Management System (PMS) unstable foundation areas are defined as sections of roadway that experience...

Minnesota Road Research Project - An Overview
The Minnesota Department of Transportation in cooperation with the Federal Highway Administration and the Local Roads Research Board of Minnesota is constructing the Minnesota Road Research...

Modeling of Floating Ice Sheets
Rectangular finite elements are studied and their suitability to investigate behavior of floating ice sheets is discussed. A simple model of the plate on one parameter, Wrinkler type,...

White Steel for Osaka Bay
Wind, earthquake and aesthetics were the design determinations for Japan's Higashi-Kobe Bridge. The designers also had to consider the man-made bay infill site and a directive...

New Support for Pin-Hanger Bridges
To promote safety of their bridges, many state highway departments are considering ways to add auxiliary support to existing pin-hanger bridges. The Pennsylvania DOT and its open-end consultant...

Trouble on the Waterways?
Crumbling highways and bridges can cripple the U.S. economy. A lesser known transportation problem is the condition of our inland waterway system. Waterways are a cost-efficient, environmentally-sound...

Vine Street Reborn
Following decades of controversy and a four-year construction effort that threatened to drive both engineers and local motorists crazy, Philadelphia's Vine Street reopened...

Fixing Foundations
Conventional underpinning or pilings are still the most common construction methods used to strengthen foundations, but new grouting techniques are giving engineers some fresh alternatives....

Beyond Engineering: The Politics of Maracaibo
The Lake Maracaibo Bridge in Venezuela was built in 1959. It ranks as one of the largest and longest bridges in the world at the time it was built and contained the longest concrete cable-stayed...

An Approach to Evaluate the Sufficiency of Highway Bridges for Nuclear Spent Fuel Transportation
The transportation of radioactive spent fuel can have a significant impact on bridge structures located on designated routes. Due to the critical nature of the cargo and because of the...

Knowledge Representation for Bridge Design
An implementation of a frame-based knowledge representation language (KRL) for development of expert system applications in highway bridge design is presented. The frame-based KRL is used...

Expert System Applications for Bridge Engineering
Expert systems (ES) are computer programs that attempt to simulate the reasoning processes and knowledge of a human expert. The particular problem of bridge analysis/design is a prime...

Optimized Models for Predicting Structural Response in Highway Bridges
Optimization techniques are a viable option for modeling bridges that have been field tested. The error between the experimental strains and the analytical strains is minimized by adjusting...

A PC-CAD System for Prefabricated Steel Bridges
A microcomputer-aided analysis and design system for prefabricated steel bridges is presented in this paper. The system was customized to perform all the required engineering to analyze,...

Computerized Bridge Monitoring System
Research at the University of Connecticut has generated a full scale vibrational monitoring system for installation on a Connecticut bridge. The monitoring system consists of a field computer...

Prestressed Concrete Bridge Design and Optimization
The computer program described here analyzes simple span highway bridges for any AASHTO live load, generates girder and slab dead loads, performs the analyses for maximum moments and shears,...

An Electronic Specification for the Earthquake Resistance Design of the Highway Bridges in Pennsylvania
An interactive C program for the seismic design of highway bridges in the state of Pennsylvania is described in this paper. The program was developed in C language on a personal computer....
