Stability of Steel Cable-Stayed Bridges

Glulam Bridge Dowel System
Strength and serviceability of timber bridges have been greatly improved by the use of glulam stringers and deck panels as the basic components. Pault and the writer studied composite...

Folded Plate Structures
The application of steel folded-plate structures has been advanced by the use of cold-formed steel metal deck. The Task Committee on Folded-Plate Structures of the Committee on Cold-Formed...

Engineering and Constructing Marine Superprojects
An examination of British Petroleum's Forties Field development and the first Mobil/Statoil Statfjord platform, both situated in the upper North Sea. Both projects were in 400 ft to 500...

Free Torsional Vibrations of Suspension Bridges
A generalized theory of free torsional vibration for a wide class of suspension bridges with double lateral systems is developed, taking into account warping of the bridge deck cross section...

Suspension Bridge Vibrations: Computed and Measured
Measured frequencies of a suspension bridge were found to differ from those calculated by a wide margin. The discrepancies were found to be caused by sliding deck joints not sliding at...

Two-Way Flexure of Steel-Deck-Reinforced Slabs
An elastically orthotropic finite element model with uniform thickness is developed that simulates the behavior of a structurally orthotropic steel-deck-reinforced concrete slab. The elastically...

Counteracting Chloride-Induced Damage to Bridge Decks with Latex and Plastic
Salt used to control ice causes deterioration of reinforced concrete bridge decks, but recent developments, though still somewhat expensive, can prevent deterioration of existing decks....

Building New Bridges from Old
The Duluth, Missabe and Iron Range Railway Co. needed a new 150-ft (64-m) two-span railroad bridge. Minimum time and low cost were the demands. In response, the designers used steel girders...

Temperature Distributions in Composite Bridges
Variations in temperature within a typical interior deck-stringer section of a composite-girder highway bridge are investigated for mid-Missouri weather exposures. The exposures correspond...

Composite Bridge Decking by Stage-Deck Jacking
Stage-deck-jacking consists of jacking a length of precast deck onto the steel girders. This liberates the casting bed which can then be used for a second length of deck. The formwork...

Alternate Bids for Bridge Deck Repair
The 45 yr old Smith Street Bridge (also known as the Bausch Memorial Bridge) over the Genesee River in Rochester, N.Y., is scheduled for rehabilitation. The extended period of exposure...

Effects of Turbulence on Bridge Flutter Derivatives
Bridge flutter derivatives have heretofore been obtained from models almost exclusively tested under oncoming laminar flow conditions. This paper demonstrates how a section model teest...

James B. Eads and His St. Louis Bridge
Eads Bridge at St. Louis, a century old engineering achievement, was designed, promoted, and built by an intensely dedicated and self-educated man, James B. Eads. This structure was an...

Vibration Analysis of Plate-Grid Decks

Plastic Analysis of Orthotropic Skew Metallic Decks
A solution is developed to predict the structural response of orthotropic skew metallic decks undergoing large deflections into the elastoplastic range leading to their ultimate load-carrying...

Behavior of Steel-Deck-Reinforced Slabs
Results and behavioral characteristics are presented for five full-scale two-way slabs tested to ultimate. The concrete slabs were reinforced with composite corrugated cold-formed steel...

Time-Dependent Analysis of Composite Frames
A step-by-step computer method is presented for the analysis of the time-dependent stresses and deformations of continuous composite concrete beams and plane frames. It accounts for the...

Field Impregnation Techniques for Highway Concrete
The corrosion of reinforcing steel due to the penetration of deicing salts poses a considerable problem in bridge decks. One approach which has received much attention has ben impregnation...

Mammoth Transshipment Terminal Links Montana Coal to Michigan Power Plant
In 1973 Detroit Edison contracted with the Decker Coal Company for 200 million tons (181 Tg) of Western low-sulphur coal over a period of 26 years to meet its requirement for low-cost,...
