Privatization Takes Its Toll
When Congress passed and President Bush signed into law the Intermodal Surface Transportation Efficiency Act of 1991, the bill's provisions designed to encourage private-sector...
Meshing Computer Technologies
A growing number of clients, especially state DOTs, are requesting computer-aided design (CAD) documents in a specified format, leaving consulting firms to wonder how many different CAD...
Environmental Consulting Grows Up
The environmental engineering industry got its first taste of maturity in 1992, courtesy of the weak U.S. economy. Revenue growth, which had raced along at a 25%-30% clip for years, abruptly...
Relationships with Architects and Owners
There are many issues which affect the relationships between structural engineers and on the other, the owner clients. This paper discusses some of those issues from the point of view...
Developing a New Construction Policy for Bridge Management
The SHRP Program and other rehabilitation strategies are based on extending the life of concrete bridge elements. In the Bridge Inventory are a number of bridges that must be reconstructed....
Serviceability Reliability Analysis of Wood Beams
The effect of creep deformations on the serviceability reliability of single wood beams is investigated. Using stochastic load models and a time-dependent stress-strain relationship, the...
Fatigue Damage Accumulation Under Non-Gaussian Loads
The stochastic fatigue life prediction method, namely the Rayleigh approximation method, is almost exact when the loading is both normal (Gaussian) and narrowband. However, in many realistic...
Performance and Serviceability of Composite Floors
Concrete slabs on steel deck are the most common type of floor system in use today. This system of construction is particularly advantageous when ultimate strength design (LRFD) is used....
Vibration of Composite Floors
An AISC/CISC guideline on floor vibration is being prepared to help practitioners design to avoid floor vibration problems and to remedy problems that occur in practice. This paper provides...
How to Include Reliability Constraints in Structural Optimization
Structural optimization is a complex process made of design cycles aimed at finding the best possible solution. At each design cycle ultimate and/or serviceability limit states must be...
Embankment Dam Safety
Procedures for identification and evaluation of conditions which can lead to catastrophic dam failure through either piping or deep seated instability of the downstream surface are presented....
The Douglas Dam Emergency Response and Rehabilitation
Through the timely response of the Owner, the potential failure of Douglas Dam was averted, and lives and property downstream were protected. The economic losses created by loss of irrigation...
Nuclear Fuel Waste Disposal: The Canadian Consultative Approach
Over the past two decades society has demanded more public participation and public input into decision-making by governments. Accordingly, development of the Canadian concept for deep...
Marketing Strategies for Engineers
Engineers face the constant challenge of informing the public and their potential users of their capabilities and the benefits that may be achieved from their services.
Information Technology: Panacea or Poison?
Consulting engineering is entering a period of dramatic change which will provide opportunities and threats. Pressure on fee levels and changing markets are necessitating a greater emphasis...
Intelligent Systems for Information Retrieval in Construction
The last three decades of the scientific and business market have been signed by information revolution. In construction, large amounts of information are manipulated and consulted. Information...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
Assessment of Guideway Systems for Maglev Applications
Recognizing the potential benefits of MAGLEV high speed mass transportation systems, three innovative guideway systems have been evaluated herein from the viewpoint of: (1) loads and performance...
Runway Rehab: A Case for CADD
Hired to design and monitor construction at Boston's Logan Airport, engineers at S E A Consultant's quickly realized that they would have to supplement their...
The Role of Information for Offshore Natural Gas
Natural gas may play a larger role in the Nation's energy mix. Extensive reservoirs of natural gas exist on the Outer Continental Shelf (OCS). But exploration for oil and gas on the OCS...
