Application of Field Data to Serviceability and Life Prediction of Highway Bridges
Serviceability of Earth Retaining Structures
Civil Engineers increasingly face decisions concerning the serviceability of existing earth retaining structures. Serviceability limit states describe the functional disruption which occurs...
Information, Global-Style
The quality, timeliness and accuracy of information can give an international architectural, engineering and consulting firm a distinct competitive advantage, and the wrong system can...
Getting Together for Sustainable Development
With environmentally sound development getting increasing attention, there is a need to bring experienced environmental engineers together with counterparts in the developing world who...
Predicting Paint's Service Life
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...
Natural Hazard Issues in International Structural Engineering
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...
Environmental Consulting Firms More Profitable, New Study Discloses
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...
