Changes in Bridge Deck Flutter Derivatives Caused by Turbulence
This paper discusses some of the results of a wind tunnel study that tested the aeroelastic stability of section models in smooth and gusting flow. Wind gusts several times longer than...
A Discrete Model for the Estimation of the Elastic Abutment Stiffness
The purpose of this paper is the presentation of a simple method for the estimation of the abutment stiffness. In this method, the abutment is represented as a uniform rigid plate with...
Seismic Isolation of Bridge Structures
Seismic isolation concept has been extensively developed and applied in New Zealand and is receiving increased attention in the United States. Two bridge projects have incorporated the...
The Atlantic Palace: Part I Structural System Selection Based on Wind Tunnel Testing
The location of the structure in a coastal area susceptible to high winds, the irregular shape and height of the building and the desire for more accurate wind loading and acceleration...
Monitoring a Bridge's Pulse
The Sunshine Skyway Bridge, which collapsed in 1980, is being replaced by the Florida Department of Transportation. The new Sunshine Skyway Bridge, which spans Tampa Bay between Bradenton...
Salvaging the Zilwaukee
In 1982, construction of the Zilwaukee Bridge in Michigan was disrupted when the launching truss failed to hold a precast concrete segment near Pier 11N, severely deflecting the cantilever...
Bridge Management: Computer Aided Priorities

Nondestructive Evaluation of Timber Bridge Piles
A nondestructive technique for the determination of the in-place strength of timber bridge piling is presented herein. The testing technique is the ultrasonic wave propagation method in...
Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...
Seismic Design of Braced Steel Frames
Seismic behavior of a six-story, K-braced structure without backup ductile moment-resisting frames designed according to the current Uniform Building Code is studied in this paper. The...
Building a Bridge Within a Bridge
The City of Grand Rapids had to replace an aging bridge connecting vital commercial centers on opposite sides of Michigan's Grand River. The city's consultants...
Timber in Bridges of West Coast
Experience has shown that timber can function very well as a bridge material. Proper inspection procedures combined with a structured maintenance program can improve the performance of...
Software for Optimum Design of Highway Bridge Beams
