Bridge Management Research Needs
The present article deals with some aspects of bridge management of particular interest to bridge engineers and to bridge users at the moment. It addresses questions such as life-cycle...
Long Life Fatigue Behavior of Welded Steel-Bridge Girder Details
The Federal Highway Administration is nearing completion of a five year, 1.5 million dollar effort titled 'Variable Amplitude Load Fatigue' to investigate the behavior of welded bridge...
Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...
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...
Role of Economics in Endangered Species Act Activities Related to Snake River Salmon
The development of recovery actions for the species of Snake River Salmon listed under the Endangered Species Act (ESA) must consider a wide range of actions covering the different life-cycles...
The Evolution of Conservation Rates in Phoenix, Arizona
Conservation or increasing block rates first implemented in Phoenix, Arizona in 1982 were reexamined by a three year study involving Water Department staff, a Citizen Rates Committee and...
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.
Modeling Facility Engineering Processes & Data Using the P-C Approach
A facility engineering process typically involves participants from different disciplines, several life-cycle phases, and many computer applications. In this paper, we propose the Primitive-Composite...
Technology Framework for Computer Integrated Construction
