Transient Dynamic Response Analysis of Embedded Rigid Foundations
A simplified approach for the transient dynamic response analysis of embedded multiple rigid foundations is presented. The approach is based on approximate time-domain formulations of...
Subgrade Model for Static and Dynamic Response Analysis of Surface Foundations
A new subgrade model is presented for the static and dynamic response analysis of surface foundations. The model consists of a number of horizontal layer model units. Each model unit is...
Foundation Studied for Turbine-Generator on Liquefiable Soils
Turbine-generator foundations are generally constructed of concrete in the U.S.A. This paper deals with the dimensioning and evaluation of a turbine foundation in Oxnard, California. The...
Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...
Axial Capacity of Pressure-Injected Piles: A Cavity Expansion Model
The application of cavity expansion theory to the development of a mathematical model for predicting the ultimate axial capacity of pressure-injected piles in cohesionless soils is presented....
Countering Terrorist Threats
Musacchio & Rozen assessed the risks and vulnerabilities to a possible terrorist attack of the data processing center of a large European bank. With the increasing use by terrorist...
Computer Utilization in Structural Engineering
This volume contains the papers presented at the 1989 Structures Congress sponsored by the Structural Division of the American Society of Civil Engineers that deal directly with the application...
Structural Design, Analysis and Testing
This volume contains the papers presented in 21 sessions of the 1989 Structures Congress held in San Francisco. The papers cover a wide range of topics including types of construction...
Interactive Aircraft Section Calculations for Drag
Large interactive computer programs are being called upon with increasing frequency for the preliminary and conceptual design of aircraft. One drag component which can be estimated at...
Design of Plastic Piece Parts
This paper describes a computer assisted design process originally developed at the University of Wyoming and now implemented in commercial software. In order to address the need for broadly...
A Parallel Partitioning Method for Large-Scale Circuit Simulation
In this paper, we discuss a partitioning method for large-scale circuit in parallel computer simulation. The partitioning method maps the sparse and irregular circuit equations to a special...
Computerized Dynamic Human Factors Mannequins Assess and Create Products and Environments for an Aging Population
A PC-based human factors symbol library helps make designs accessible to a broad populace. The system and research results described were developed in three phases. Knowing that in order...
Constraint Based Design from Research into the Classroom
Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified...
Stereolithography
Stereolithography is a three-dimensional printing process which produces accurate copies of CAD solid or surface models directly from CAD data. The process uses a moving laser beam, directed...
Risk of Waterborne Infectious Illness Associated with Diving in the Point Loma Kelp Beds, San Diego, CA
There is considerable interest in estimating the risk of bacterial and viral illness (i.e., disease, infection) associated with scuba diving in the Point Loma kelp beds located within...
Risk Assessment for TCE and Related Chemicals Based on Multi-Component, Multi-Media Transport Models
Trichloroethylene (TCE) is known to undergo anaerobic transformation and produces daughter products including dichloroethene, and vinyl chloride which have been known as possible carcinogenic...
Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...
Modeling of Gaseous Emission from Landfills and Other Area Sources
Several dispersion models based on the Gaussian equation are evaluated to assess their relative utility in modeling emission dispersion from an area source, such as a landfill. The VAPOR...
Analysis of Model Uncertainty Using Bayesian Monte Carlo
Bayesian Monte Carlo analysis combines Bayesian inference with standard Monte Carlo techniques to provide improved estimates of the uncertainty in water quality model parameters and results....
Longterm Response of Lakes to Acidic Deposition
The longterm response of lakes in the northeastern United States to different levels of acidic deposition was predicted by using a lumped parameter hydrologic/biogeochemical model, the...
