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...
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...
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...
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...
A Computer-Integrated Approach to Teaching Engineering Mechanics
A brief survey is first presented of the evolution of computer hardware and the effect of that evolution on structural software applications and development during the past forty years....
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...
Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...
Finite Element Limit Load Analysis by the Static Approach Using Nonlinear Programming
The static approach to limit analysis using finite element modelling is formulated as a nonlinear programming problem and applied to the vertical cut problem. Whereas the kinematic approach...
Contemporaneous Development of Field Data: Transportation Construction Claim Defense
This paper addresses the continuing development of a construction field database system documenting resources applied on the jobsite by Contractors. The paper focuses on the case study...
Effects of SPT Equipment and Procedures on the Design of Shallow Foundations on Sand
The effect on our computations of bearing capacity and settlement of shallow foundations suggests that as more efficient SPT hammers and procedures are used, our shallow foundation designs...
53 WAK Tests on Spread Footings
Research on the prediction of soil stiffnesses of spread footing-soil systems using Wave Activated Stiffness (K) or WAK tests was conducted. As discrete lumped-parameter model with a mass,...
WAK and Full-Scale Load Tests on Granular Fill
For footings on granular fill that includes cobble- and boulder-size materials, in situ tests cannot be used to estimate foundation settlement because such fill is difficult to explore...
