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...
Demand/Supply Relationship in Transportation Network Design Problems: A Genetic Algorithm Approach
The cumulative genetic algorithm (CGA) has its significant advantages over the heuristic algorithms in dealing with transportation network design problems. Using CGA, the entire solution...
Conceptual Models of Product, Project and Document Data; Essential Ingredients of CIC
A number of current on-going national and international standardization efforts which develop standards for information structures in construction are reviewed in the paper. These concern...
DETMOD: A Desktop Estuarine Transport MODel
A microcomputer based numerical model designed to simulate the transport of substances within an estuary is presented. The Desktop Estuarine Transport MODel (DETMOD) features a Graphical...
Practical Solution of the Flexibility to Stiffness Transformation Problem With a Mathematical Assistant for the Personal Computer
This paper will show how a relatively complicated structural mechanics problem can be solved easily with a symbolic manipulation program. Specifically, the authors will demonstrate how...
Application of the Phase Change Process to One-Dimensinal Consolidation Behavior of Peat
In this study, based on the fact that the pore of fibrous peat consists of the macro (outer) pore between organic matters and the micro (inner) pore inside organic matter, an approximate...
Prediction of Low Level Vibration Induced Settlement
A prediction model of vibration induced settlement was developed for small to intermediate vibration levels (0.25-1.78 cm/s). Seven factors affecting vibration induced settlement such...
Comparison of Predicted and Measured Settlement of a Test Embankment Over Soft Soil
A test embankment was instrumented with six (6) settlement plates, three (3) vertical extensometers, two (2) inclinometers, and two (2) horizontal profilers in order to verify settlement...
Application of the Diflupress L.D. Field Test to Settlement Calculation
Electricite de France developed a new in situ measurement apparatus (Diflupress L.D.) in order to predict the delayed settlements that can appear under heavy constructions. From the experimental...
Load-Settlement Prediction of Footings on Steep Slopes
The use of spread footings on slopes is a common practice in the design of bridge foundations. Footings are generally constructed in the slope or at its crest to minimize the bridge length,...
Reliability-Based Assessment of Corps Structures
Due to the limited amount of funding available for maintenance, rehabilitation, and replacement of aging Corps structures, the director of civil works, Headquarters, U.S. Army Corps of...
A Theoretical Framework for Risk Assessment
This paper puts forth a theoretical framework for the development of any risk model. The focus is on the distinction between model and parameter uncertainty....
Coastal Eutrophication and Temperature Variation
A 3-D hydroecological model has been developed to simulate the impact of climate-change-induced daily temperature variation on coastal water quality and eutrophication. Historical daily...
Federal Risk Management Policy: Where Is the Federal Government Heading? Where Are the Problems?
The paper summarizes the first session of the conference which discussed the present state and problems of federal risk management policy. Topics discussed include efficacy of models on...
Risk Management Strategies for Natural, Manmade, and Technological Hazards
The paper summarizes the fourth session of the conference which discussed risk assessment approaches in bio/chemical hazards; specific studies on people's behavior and views of natural...
Recovery of Chromium from Spent Plating Solutions by a Chromyl Chloride Process
A novel chromyl chloride process has been investigated for the recovery of hexavalent chromium from spent plating solutions. In this process chromium is converted to chromyl chloride by...
A Coupled Mass Transfer and Surface Complexation Model for Uranium (VI) Removal from Wastewaters
A remediation technique has been developed for removing uranium (VI) from complex contaminated groundwater using flake chitin as a biosorbent in batch and continuous flow configurations....
Modeling of Chemical Inhibition of Nitrification
This work contains two quantitative structure-activity relationships (QSARs) modeling chemical inhibition of nitrification, one for heterocyclic compounds and one for acetylenic materials....
Modeling of Biofiltration of Natural Organic Matter in Drinking Water Treatment
A multi-substrate model of the biofiltration of natural organic matter in drinking water was developed and successfully applied. This model assumes that biofiltration is a two-step process...
2D Finite Element Modelling of Flooding Due to River Bank Collapse
To compute the flood propagation over an initially dry area a new set of 2D equations has been recently proposed which accounts for the ground unevenness effects. The paper presents a...
