Random Thermal Stresses by Finite Elements

Response of Taut Strip Models to Turbulent Wind
An experimental investigation was conducted to clarify the fundamental behaviour of the proposed taut strip wind tunnel model of long span bridge deck systems. The study shows that this...

Load Capacity of Concrete Bridge Decks
The behavior of two reduced-scale concrete bridge decks subjected to simulated wheel loads was evaluated in a series of tests. One slab was reinforced in accordance with AASHTO requirements;...

Prestressed Decks in Continuous Composite Bridges
A convergent series solution, using the concept of equivalent orthotropy, is employed to analyze continuous composite bridges under static loads. The effect of the interaction between...

Suspension Bridge Vibration: Continuum Formulation
The methodology of the free vibration analysis of suspension bridges with horizontal decks is refined and extended, utilizing a continuum approach to include both the coupled vertical-torsional...

Behavior of Skewed Beam and Slab Bridge Decks
A stiffness method for the analysis of monolithic beam and slab skew bridges is developed, the deck geometry being modeled with two-node beam and four-node skew plate finite elements....

Golden Gate Bridge: Deck Investigation
Detailed investigations have found widespread defects and local failures in the roadway slab of the Golden Gate Bridge. Cracking exists throughout over transverse reinforcing bars. Concrete...

Offshore Construction: Site Design Considerations
A milestone in the construction of an offshore production/drilling platform is reaching self-sufficiency. In attaining this goal the construction involves three basic phases: (1) The work...

Bottom-Supported Concrete Platforms: Overview
A concrete gravity platform consists of a cellular caisson made up of a collection of large concrete cylinders supporting three or four large diameter tubular columns with a steel frame...

Stochastic Control of Structures
The problem of how to control a structure against random disturbance of known statistical properties is investigated. An optimal control law can be found as a combination of closed-loop...

Uniform Loading for Steel-Deck-Reinforced Slabs
Previous research at Iowa State University has resulted in a shear-bond design equation which was based on data obtained from tests utilizing concentrated line loads on one-way elements....

Field Measurements of Muskwa River Bridge
The behaviour of a continuous, steel-concrete composite box girder bridge was monitored during construction of the concrete deck and during the first three years of operation. It was observed...

Point Loads on Composite Deck-Reinforced Slabs
The behavior of composite deck-reinforced floor systems under concentrated loads is described. Laboratory experiments show that these floor systems may have a considerably larger capacity...

Parking Deck Deterioration from Chlorides

Stadium Completed Night Before Game
Construction problems with a major addition to the Clemson Memorial Stadium in Clemson, S.C., halted construction for four months. In order to make up the time, the design firm had to...

BRANDE IV — A Bridge Analysis System

Re-decking a Bridge With Precast Concrete
Re-decking a 1627-ft deck girder bridge on the Pennsylvania Turnpike with precast concrete slabs allowed the bridge to remain partially open to traffice during the entire construction...

Venezuelan Dock Features Unconventional Design, Quick Set-Up
This structure, designed by Caracas design/construct firm Precomprimido, kills two birds with one stone: a series of huge, hollow concrete cylinders both support the service deck of the...

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...
