Damage Tolerance Analysis in Structural Rehabilitation
The rehabilitation of existing structures requires an evaluation by the structural engineer of past performance to determine the extent of existing damage. Following evaluation of the...
How to Optimize Frames Using Plastic Design Concept
An optimal design procedure using plastic design concept was presented. For low-rise building frames, optimal plastic designs can be made using the plastic limit load as a basis of design....

Switzerland: Rail Access to Airports and the Fly-Luggage System
Swissair and the Swiss Federal Railways (SBB) offer a unique service for air passengers travelling to and from their Swiss airport of departure or arrival. In conjunction with private...
Intelligent Decision Support System for Stage Discharge Analysis
A Decision Support System (DSS) for fitting stage-discharge (S-D) relations is being developed by the University of Manitoba, Facility for Intelligent Decision Support, for Environment...
Effectiveness of Retrofit in Multi-Family Apartments
This paper reports the results of an evaluation research study of the cost-effectiveness of water-conserving, residential retrofit plumbing devices. By means of a 'quasi-experimental,'...
Water Policy Change, Implications for Pyramid Lake
Pyramid Lake is part of and is surrounded by the Pyramid Lake Indian Reservation. The river system has been administered by a Federal water master serving the Federal court system with...
Storm Water Pollution Control for Industry: Developing Effective Guidelines Through Public Involvement
A regionwide storm water pollution control program in the Santa Clara Valley, California, includes an active industrial source control component that is designed and implemented as a public...
The Law of the Colorado River: Can It Cope With Severe Sustained Drought?
This paper analyzes the Law of the River from the perspective of its effect on allocation decisions in the event of a long term, severe drought. The analysis is organized in a manner familiar...
Development of Fisheries Models for the Missouri River System
This paper describes how the value of fisheries resources under various Missouri River operating alternatives was determined. The four fish communities evaluated were the reservoir cool/warm...
Conservation Before and After: The Impacts of Increasing Block Rates on a Fully Metered System
Denver Water's inside residential consumption and revenues changed dramatically during a metering program and a conversion to inclining block rates. We analyze these two changes and make...
A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...
The Job-Order Contracting Solution
A new method of contracting, Job Order Contracting, combines many contracts into one administered by one project team. They are competitively bid, indefinite delivery, indefinite quantity,...
A New Angle on Ground-Water Remediation
When engineers from Black & Veatch Waste Science (BVWS) went to Tinker Air Force Base to examine the site of a hazardous waste cleanup job the service had hired them for, they...
Multimedia in Civil Engineering
Multimedia inspires so many claims and hype that it can be hard for engineers to figure out what's real and what's not. The truth is that multimedia holds great...
Circle Integration
Based on the results of proof-of-concept experiments, we propose that an integrated suite of software tools can support both automation and integration of several components of AEC design...
Functional Analysis of the Envelope Design Process for Integrated Building Design
Building envelope failures account for a great portion of building failures. The number of envelope deficiencies would be reduced if the design process was integrated. Integration would...
Construction Problem Solving in a Cooperative Distributed Agent Environment
This paper outlines the research being undertaken by the authors to determine how experts develop solutions to construction problems in a cooperative distributed agent environment which...
Improved Computer Simulation of 3D Wind Flow Around a Building
A two-layer method combining the k-? model with the one-equation model near the wall has been tested in computing the wind conditions around a cubic building. In contrast with the simple...
