All Decked Out
After 50 years of wear, the deck of New York City's Williamsburg Bridge was buckling and badly in need of replacement. In 1994, consultants recommended replacing the deck...
A Self-Balancing Laminate
A self balancing wood laminate has been developed based on the principle of orthotropic elasticity. Lumber is cut into three sections in the flatwise plane and each side member is turned...
Neural Network Learning in Structural Engineering Applications
Neural networks based on the backpropagation learning algorithm have been used in a number of structural engineering applications. The paper classifies the different types of relationships...
Random Response of Multicrystalline Structures
An approach to the probabilistic modelling and analysis of multicrystalline microfabricated beams is presented with application to micro-electro-mechanical systems (MEMS). Random, textured...
The Generalized Brazier Problem for Orthotropic Straight Tubes of Finite Length
A new engineering approach, based upon a mixed variational functional, is presented for the analysis of the nonlinear static behavior of thin-walled, circular-cross-section cylindrical...
Probabilistic Approach to Stress Distributions for Orthotropic Wood Plates
Probabilistic approach to the stress distributions of an orthotropic wood plate is discussed. The stress distributions for the orthotropic elastic media are fully dependent of the material...
Golden Gate Bridge Improvements
The Golden Gate Bridge, Highway and Transportation District engineer talks about improvements made to the Golden Gate Bridge since opening day. Improvements covered include: wind bracing,...
Aluminum Orthotropic Bridge Deck Verification
This paper reports tests conducted to evaluate an aluminum orthotropic deck. Approximately 60 welded T-joints with 6061-T6 stems and 5456-H321 plate were subjected to flexural fatigue...
Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...
George Washington Bridge Redecked with Prefabricated, Prepaved Steel Panels
The Port Authority of New York and New Jersey has embarked on a �37,000,000 project to totally replace the upper roadway of the 46-yr old George Washington Bridge. The scheme, chosen from...
