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...
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...
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....
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...
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...
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...
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...
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...
The State of the Art of Bridge Management Systems
The development of Bridge Management Systems, and Pontis in particular, requires states to change many of their traditional inspection and record-keeping procedures. If these are changed,...
Tie Model: A Crosstie Replacement Planning and Costing Model
The Tie Model described in this paper is a maintenance planning and life-cycle costing model for wood crossties. The model includes a number of different failure modules to predict crosstie...
