Dynamic Analysis of Beams on a Pasternak Foundation
Since many years pavement engineers apply very simple statical models to analyze their specific problems. The development of numerical tools and easily available computer power make much...
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...
Tutorial: Fuzzy Expert Systems
This extended abstract presents a brief introduction to a tutorial on fuzzy expert systems. The precepts of set theory and classical predicate logic are briefly reviewed to provide a foundation...
A Numerical Procedure to Compute Bearing Capacity of Shallow Foundations
A simple numerical procedure of calculation of bearing capacity of shallow foundation is proposed. This procedure employs the Terzaghi-Prandtl model of general shear failure. In this paper,...
Foundation Uniform Pressure and Soil Structure Interaction
The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation...
An Integrated Design/Construction Research Program for Infrastructure Rehabilitation
The quality of America's infrastructure today is barely adequate to fulfill current requirements, and sufficient to meet the demands of future economic growth and development. This serious...
New Wells Safeguard Scenic Tahoe
Surface water for drinking and for snow-making is becoming scarce in the Lake Tahoe region, along the California and Nevada border. New Environmental Protection regulations regarding surface...

Coastal Management and Ocean Industries in East Germany, from Central Planning Ineffectiveness Towards Local and Regional Development Strategies
In so far, the preconditions for the implementation of decentralized development tools both in coastal management and in ocean industries may be quite ideal in East Germany: there is the...
Environmental Compliance and Offshore Oil and Gas Exploration and Production
The economic impacts of multiple environmental regulations of offshore oil and gas exploration and production are examined using an integrated, investment-production-regulatory model developed...
The Whole Picture: Federal Statutory and Regulatory Authorities Which Govern Oil and Gas Activities on the Alaskan Outer Continental Shelf
Oil and gas activities conducted on the Alaska Outer Continental Shelf (OCS) are subject to multiple Federal laws which result in safe operations and environmental protection. Lessees...
Vertical Erosion on Beaches and the National Flood Insurance Program
During the 25 years that the National Flood Insurance Program (NFIP) has been in existence, there has been an increasing recognition of the contribution of both episodic and long-term...
Resource Extraction Activities in the Coastal Zone?The Impact of Offshore Oil Production on Coastal Communities
There are few studies that examine the impact of offshore oil extraction on social problems, educational attainment and economic health of communities. The results of this study demonstrate...
An Ongoing Field Study to Evaluate the Impacts and Direct Effects of Offshore Dreding Activities on Benthic Organisms
Instrumentation and sampling involve box coring, otter trawling, the use of a towed sled carrying video camera, and a sidescan sonar device. The baseline collection phase of the study...
Equations to Predict Critical Submergence at Horizontal Hydraulic Intakes
The formation of free surface vortices at hydraulic intakes can disrupt operation and damage machinery. It is also a serious safety concern. Theoretical investigations and laboratory tests...
Bridge Scour Analysis in New Jersey: Which Scour Factors Matter Most?
This paper seeks to correlate the scour susceptibility of bridges with such observable characteristics as bridge design features, waterway characteristics, and geographic and geologic...
The Separated Flow Around a Circular Bridge Pier
The unsteady separated flows around a flat plate/cylinder junction and a scour hole/cylinder junction were investigated experimentally. The flow in the plane of symmetry was presented....
Top Width of Pier Scour Holes in Free and Pressure Flow
The maximum top width of the local scour holes at piers is shown to be a simple function of the scour depth and the angle of repose of the bed material in water. Knowledge of the top width...
Preliminary Studies of Pressure Flow Scour
Bridges that become inundated during floods have slightly pressurized flow that impacts bridge piers and creates an aggravated scour condition. Results of two preliminary laboratory studies...
