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...
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...
Scour Analysis for Bridges over Missouri and Mississippi Rivers
Engineering services are being provided for three bridge crossings, two over the Missouri River and the other over the Mississippi River. Scour consideration for the bridged waterways...
21st Century Composites Require ASCE Standards and SDS
This paper describes the ASCE initiative and discusses the philosophy and needs for the structural design system (SDS) of which the standards will be a part. Our perspective is from the...
Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...
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...
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...

Earthquake Hazard Investigative Procedures for Central United States Waterworks
The vulnerability assessment of Central United States waterworks for earthquake hazards is a developing engineering practice for civil engineers in Arkansas, Missouri and states close...
Corrosion Fatigue of Deepwater Offshore Materials
Evaluation of the fatigue life of offshore structures operating in depths of up to 10,000 feet (3,048 m) requires knowledge of the combined effect of axial and hydrostatic loading on the...
Coastal Engineering—The Past!, The Present!, The Future?
The author discusses past and present practices of coastal engineering, and speculates on the diredctions that the profession will take in the future. Also discussed is the question of...
Investigation of Coastal Conditions at Oregon Inlet, NC for the Replacement of the Herbert C. Bonner Bridge
The Bonner Bridge across Oregon Inlet was constructed in 1962 and is approaching the end of its service life. Planning for a future crossing must consider natural inlet migration expected...
