Drafting of an ISO Standard for Leakage Tests on Packaging for the Transport of Radioactive Material
A working group (TC85/SC5/WG 10) has been formed by ISO for the drafting of an international standard covering the leak testing of radioactive material transport containers. A certain...
Cask Systems Development Program Seal Technology
General design or test performance requirements for radioactive materials (RAM) packages are specified in Title 10 of the U.S. Code of Federal Regulations Part 71 (10 CFR 71). Seals that...
Testing of Materials and Scale Models for Impact Limiters
Aluminum Honeycomb and Polyurethane foam specimens were tested to obtain experimental data on the material's behavior under different loading conditions. This paper reports...
GA-4/GA-9 Honeycomb Impact Limiter Tests and Analytical Model
General Atomics (GA) has a test program underway to obtain data on the behavior of a honeycomb impact limiter. The program includes testing of small samples to obtain basic information,...
A Decision Support System for Performance-Based Site Characterization
The complex and dynamic requirements of site characterization present a major management challenge. ParaTrac, a regulatory and technical information system, is described as a valuable...
Optimized Models for Predicting Structural Response in Highway Bridges
Optimization techniques are a viable option for modeling bridges that have been field tested. The error between the experimental strains and the analytical strains is minimized by adjusting...
A Prototype of the Uniform Building Code Using Hypertext
The earthquake section of the Uniform Building Code has been implemented using the hypertext technology. The information was broken down into many interrelated nodes. Figures were scanned...
Accurate Response Analysis of Seismic Distributed Mass Systems
A dynamic analysis technique of distributed mass structures is presented with a combination of the dynamic load factor approach and the dynamic stiffness matrix method. The dynamic stiffness...
An Electronic Specification for the Earthquake Resistance Design of the Highway Bridges in Pennsylvania
An interactive C program for the seismic design of highway bridges in the state of Pennsylvania is described in this paper. The program was developed in C language on a personal computer....
COMBAT.PC; a New Windows-Based Tool for Three-Dimensional Dynamic Analysis of Multi-storied Building Structures
By some accounts, analytical capability without the power of visualization is little productive; visualization is the tool that will turn computational power into practical results. COMBAT.PC...
Computer Implementation of Seismic Building Codes
The objective of this work is to implement the provisions of building codes current in the U.S. as well as those of other countries for the seismic resistant design of buildings. The work...
Macro-Model for Inelastic Low-Rise R.C. Shear Walls
This paper presents an analytical technique for calculating static and seismic response of low-rise shear wall structures. The displacement response is resulting from bending, shear, and...
Active Control of Structures with Soil-Structure Interaction
The objective of this paper is investigate the effect of soil flexibility on the performance of the active control system for seismic-excited buildings. By using the critical-mode control...
Boston's Sewage Outfall
The centerpiece of the Boston Harbor cleanup plan will be the sewage plant on Deer Island, which will treat water from 43 municipalities in the Boston metro area�500 mgd to start. In order...
Remote Sensing for Seismic Hazard Assessment of a Proposed Nuclear Power Station, North Wales, UK
During the seismic hazard assessment for a proposed nuclear power station in North Wales, UK, a remote sensing study was carried out in conjunction with other, wide-ranging geological...
New Jersey Department of Transportation Bridge Scour Evaluation Program
The New Jersey Department of Transportation's (NJDOT's) newly initiated bridge scour investigation program will assess the vulnerability to failure by scour of...
Field Investigation for Leachate Flow in a Landfill
Field investigation for leachate flow was done for the Fresh Kills landfill at Staten Island, New York. The leachate monitoring program included data collection from the field for a six...
AI Development Environment for the Maintenance of Existing Buildings
A specific structural typology is considered with a deep expertise available on the subject. The 'state of health' of a single building is assessed by an expert...
Interaction of Elastic Waves with Axisymmetric Cavities in a Half Space: A Combined Finite Element-Boundary Integral Approach
A hybrid numerical method is presented to investigate the interaction of elastic waves with axisymmetric cavities on the surface of a half space. In this method the near field which consists...
