Historic American engineering projects sampled in this article represent those documented in
Sewage Plant Engineered for Value
The Camden County (NJ) Municipal Utilities Authority was formed in 1972 to cope with suburban growth that had overloaded 34 primary treatment plants. By the early 1990s, the Authority...
Geotechnical Exploration and Site Preparation Techniques for Large Mall in Karst Terrain
A large commercial mall and secondary developments were planned for construction in a karst area near Clarksville, Tennessee. A geotechnical exploration was conducted to evaluate the occurence...
Treatment of Karst Along Tennessee Highways
The construction and maintenance of highways in karst areas of East Tennessee has resulted in the occurrence and treatment of induced sinkholes along the ditchlines of numerous highways....
Geosynthetics for Soil Improvement: A General Report and Keynote Address
The paper summarizes major developments in the field of geosynthetics since the previous symposium in 1980. The paper addresses the engineering functions of major types of geosynthetics,...
Highway Factors in Truck Wrecks
An examination is presented of highway factors as they interact with driver and vehicle factors in large truck accident causation. Examples of highway defects are discussed along with...
Effects of Driver Factors and Training on Wrecks
A training program for professional drivers is reviewed. The effects of driver factors, as well as their training, on accidents is presented....
Truck Operating Characteristics in Relation to Safety
For a two-year period large truck crashes on the interstate system in Washington State were investigated using a case-control method. For each large truck involved in a crash, three trucks...
Design Considerations for Trucks in Work Zones
In an Eastern state a 3. 8 mi (6. 2 km) work zone had 14 accidents during a project duration of 120 days. Eleven of the 14 accidents occurred at temporary crossovers where traffic was...
Accommodation of Large Trucks: Traffic Control Issues
The objective of this paper is to identify ways that large trucks can be accommodated safely and efficiently through traffic control. Traffic control is herein defined as encompassing...
Accommodating Larger Trucks at At-Grade Intersections
When a particular intersection serves a high volume of large truck traffic, design considerations should reflect the presence of those larger vehicles. This paper discusses three intersection...
A Reassessment of Codified Limit States Design
This paper examines the nature of design codes and their relation to engineering practice. It suggests that codes impose unjustifiable and, in the long term, destructive constraints on...
Probabilistic Design of Flexible Pavements
Numerous random phenomena enter into the process of deterioration of pavements under the effect of traffic. It is felt that improvement in current design methods could be obtained by adopting...
A Probabilistic 3-D Short-Term Slope Stability Model
A probabilistic model to analyze the three-dimensional stability of earth slopes under short-term conditions is presented. An actual failure case is studied to show the implementation...
STOCAL-II-An Instructional Software for Random Vibrations
STOCAL-II (Computer Assisted Learning of STOchastic methods) is an instructional software for teaching random vibrations and applied stochastic processes. It is based on and is an extension...
A Stochastic Seismological Model in Earthquake Engineering
Recent studies of source mechanisms and wave propagation models enable one to generate strong motions based on deterministic source and source-to-site characteristics. The normal mode...
Rehabilitation of Highway Bridges: Design and Operational Considerations
The design of a rehabilitation of a bridge which must maintain some lanes of traffic requires special consideration of construction procedures and traffic control, which are discussed...
An Expert System for Reliability Engineering
The goal in this project is to create an expert system to do failure mode investigations from 'first principles,' or the basic understanding of the way components...
Experiences with Applications of Importance Sampling in Structural Reliability Computations
This paper presents some experiences and observations relating to the use of importance sampling in structural systems reliability computations. These are presented with three examples,...
Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...
