Estimating Clay Liner and Cover Permeability Using Computational Neural Networks
The ability to provide a quick estimate of the permeability value to be expected in laboratory testing (of field samples) would help to predict potential problems in meeting the permeability...

FEM in a Design Code Environment
The results obtained from the use of finite element based analysis tools have created a new problem for designer: Which numbers do we use to check against Code limits? Most of the commonly...

A program for the Analysis of Pile Load Tests
The load capacity of piles are routinely determined from full scale pile load tests under actual field conditions. Several empirical methods were proposed for the analysis of field load/settlement...

Analysis of I-Girder Highway Bridges
Analysis of a bridge superstructure is complicated by the general geometric and loading conditions. Presented in this paper are three dimensional finite element modeling techniques used...

Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....

Computer Analysis of Continuous P/C Highway Bridge Girders with Variable Depth
A computational procedure and associated computer program were developed for the analysis and design of P/C continuous beams with variable depth. Using this program, continuous girders...

Impulse Effect on Redundancy of a Tied-Arch Bridge
This paper studies the redundancy of a tied-arch bridge using a 3-dimensional finite element computer model. By using static incremental loading simulation, a tied-arch bridge designed...

Design and Implementation of a Database for Seismic Evaluation of Structures
The seismic evaluation of large structures, such as bridges, requires a comprehensive framework for managing the data. An evaluation typically involves the dynamic analysis of a number...

Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...

SELECTCRANE: An Expert System for Optimum Crane Selection
Every major project undertaken today requires the services of a crane(s) to ensure that all materials and equipment hoisting and placement are performed in the most efficient manner. The...

Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...

Seismic Analysis of Reinforced Concrete Building Using Finite-element Techniques
The response of a reinforced concrete building subjected to earthquake loading has been obtained on a personal computer using the finite-element code STARDYNE. For preliminary design,...

Seismic Evaluation of the Macy Street Bridge, Los Angeles, California, Using 3-D Nonlinear Pushover Methodologies
Nonlinearity of the overall bridge response has begun to be incorporated in the design process through a method known as nonlinear static pushover analysis, and this step is now being...

Nonlinear Analysis and Experimental Validation of a Stiffening Truss Chord of the Golden Gate Bridge
Finite element analyses of a stiffening truss chord of the Golden Gate Bridge were conducted by the authors as part of a comprehensive seismic retrofit project conducted by T. Y. Lin International...

A Knowledge-Intensive Database System for Making Effective Use of Construction Lessons Learned
The Constructability Task Force of the construction Industry Institute (CII) sponsored as series of studies which advocate construction expert input to the conceptual planning, engineering...

Teaching Soil Mechanics Laboratories with Computer Assistance
This paper discusses the methods involved in teaching the laboratory section of an undergraduate course in soil mechanics using computer assistance. The lab covered one semester with students...

Expert System for Bridge Scour and Stream Stability
Significant engineering judgment is required to ascertain the scour susceptibility of bridges. This judgment is typically acquired through many years of experience. This paper describes...

Computer Analysis of Lateral Loading in Wood-Framed Structures
