A Case Study of Propeller-Induced Currents and Sediment Transport in a Small Harbor
The operation of vessels in marinas and small harbors can provide important driving forces affecting ambient circulation patterns and current speeds near the bottom. The case study on...
Marina Cabo San Lucas?A Case Study
Designing and constructing a high quality, state-of-the-art marina is a difficult task in major metropolitan areas such as Los Angeles or San Francisco. But when the marina development...
Landing on Frictionless Surfaces
Who in his right mind would deliberately land an airplane on a frictionless surface? Unfortunately, professional pilots occasionally encounter situations where the friction between rubber...

Riverbank Renewal
In Providence, project teams from the public and private sector worked side-by-side, rerouting two rivers and constructing a new corporate headquarters. What made the task more challenging...
Seattle's Good Neighbor Policy
The West Point wastewater treatment plant in Seattle sits on a spit of land jutting into Puget Sound. Close by is Discovery Park, a haven for nature lovers, located on a bluff above the...
Microtunneling MARTA
Microtunneling technology was used to provide temporary support for two transit tunnels that were part of the extension of the Metropolitan Atlanta Rapid Transit Authority system. This...
Knowledge Acquisition in Civil Engineering
Expert systems are an intriguing approach for transferring valuable problem-solving skills from the minds of human experts to the logic of computer programs. For the past several years,...
Seismic Ground Motion and Attenuation Relationships
A key element in the assessment of seismic hazard is the estimation of how energy from a given earthquake is affected by crustal structure along the propagation path. There are recognized...
A Seismic PRA Procedure in Japan and its Application to a Building Perforance Safety Estimation: Part 1. Seismic Hazard Analysis
A method for seismic hazard evaluation which deals with response spectrum information is presented. A local city near Tokyo facing the Pacific Ocean is selected for the case study. It...
Safety Assessment Methodology for Construction Operations
There are many factors that affect the safety of construction operations which might lead to failures and accidents. The factors are associated with random, human-based or system uncertainty....
Dynamic Load Computation for Flexible Guideways Under Moving Vehicles Within a Multibody Approach
This paper addresses the problem of the dynamic interaction of vehicles with their supporting guideway. Because of topographical and environmental reasons, modern railways and magnetically...
Model Identification of an Arch Bridge for Dynamic Analysis
The dynamic responses of a steel deck tension-tied arch bridge subjected to earthquake excitations were investigated. The 189 m (620 ft) Birmingham Bridge located in Pittsburgh, PA was...
Fatigue Reliability and Remaining Fatigue Life of Existing Steel Rail-Road Bridges
This paper presents a fatigue reliability model for the reliability-based evaluation of remaining fatigue life of existing rail-road bridges. It is demonstrated that the simple fatigue...
The Estimation of Allowable Strength Based on Fatigue Reliability of Welded Part and Base Metal of Rail in Korea
In the allowable stress design, the safety of structures have been ensured by safety factor based on static strength. Under dynamic loading condition, the allowable stress based on allowable...
The Prefab Tunnel
Jacking a prefabricated concrete arch through a railroad embankment to provide a new access ramp to the Don Valley Parkway in Toronto was done for the first time in North America. In September...
Tales From Milwaukee's Underground
Written from RETC papers and interviews, this article is a status update on the Milwaukee Metropolitan Sewerage District's $2.1 billion Water Pollution Abatement program,...
A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...
Downtown in Soft Ground
Critchfield and MacDonald describe the shield excavation of twin bus tunnels 21.25 ft in diameter and 5,000 ft long as part of the Downtown Seattle Transit Project. This $450 million project,...
