Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
Using Finite Element Analysis to Derive the Coefficient of Subgrade Reaction
The coefficient subgrade reaction is a concept used to generate spring constants which are commonly used to model the foundation subgrade in the analysis of mat foundations. This paper...
A Constraint-Based Composites Design Advisor
Most engineering problems, because they involve mathematical relations (constraints) on real valued quantities (objects), can be reduced to constraint networks. The authors speculate that...
Crack and Contact Problems in Masonry Arch Bridges
A two-dimensional finite element program has been developed to predict the load carrying capacity of masonry arch bridges with different structural defects such as missing bricks and tangential...
Optimal Seismic Design of Structures
Structural design...
Evaluation Plan for AVL Implementations
The Federal Transit Administration, as part of the Advanced Public Transportation Systems program (a component of the Intelligent Vehicle-Highway Systems initiative), is conducting the...

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...
A Process to Enhance the Flow of Engineering and Management Information at Ford Hood, Texas
This paper describes a study of the information requirements at the DEH (Directorate of Engineering and Housing) at Fort Hood, Texas which was undertaken by the U. S. Army Corps of Engineers...
The Application of Gauss Numerical Integration Method in Arch Dam Trial-load Method Program
The characteristics of Gauss Numerical Integration Method are the unequal distance between nodes and fairly high accuracy. When the number of nodes is n, the algebraic accuracy can be...
Model-Based and Interactive Planning for Predictive Plant Maintenance Management
Maintenance of process in power plants represents about 30% of the operating cost of these plants, including the cost of repair labor, materials and out side services but not the cost...
Invasion of the Zebra Mussels
At first glance, the zebra mussel looked like doom for freshwater users in the Great Lakes: small, hardy, incredibly prolific European mollusks with an affection for freshwater intakes...
Nondestructive Evaluation Techniques and Their Role in Infrastructure Management
Nondestructive evaluation (NDE) techniques can play an important role in infrastructure management. They can be used to assess current condition a well as to predict future performance...
Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...
Sonic NDT for Infrastructure Assessment
Sonic Nondestructive Testing (NDT) techniques are valuable tools for assessing infrastructure. Relatively recent innovations in the field can reveal the internal conditions of concrete...
How to Get Local Public Works Agencies to Use Structured Infrastructure Management Approaches
As more agencies consider adopting infrastructure management systems, the lessons learned in developing and supporting the use of current systems should be used to structure the support...
Airfield Pavement Management System
This paper describes a comprehensive Pavement Management System (PMS implemented at 24 airports in the kingdom of Saudi Arabia. The PMS development and implementation was completed in...
Automated Generation of NBI Reporting Fields from Pontis BMS Database
Methods to generate National Bridge Inventory (NBI) condition ratings for deck (Field 58), superstructure(Field 59), substructure (Field 60) and culvert (Field 62) from the bridge database...
Large Truck Impacts on the Highway Infrastructure: The Bridge Dimension
Recent U.S. studies have explored the productivity gains of longer combination vehicles (LCV's) and their impacts on highway infrastructure. The area least explored is LCV operations and...
