Vancouver's Skytrain Cable-Stayed Bridge?Dynamic Behaviour
This paper focuses on the dynamic behaviour of the Skytrain cable-stayed bridge under the action of earthquakes and wind. The 340 m span railway bridge is located on the west coast of...
Dynamic Behavior of Three J.S. Cable Stayed Bridges
Dynamic considerations in the design of three recently designed cable stayed bridges are discussed. The presentation includes analysis for eigenfrequencies and eigenmodes, assessment of...
Effects of Three-Dimensionality and Nonlinearity on the Dynamic and Seismic Behavior of Cable-Stayed Bridges
The cases of multiple-support as well as uniform seismic excitations of these long and flexible structures are considered; furthermore, effects of the nondispersive travelling, seismic-wave...
Comparative WWind Tunnel Testing of Bridge Road Decks
A 1:75 scale full aeroelastic model of the Quincy Bridge over the Mississippi River was tested in the National Research Council of Canada 9 m multiplied by 9 m wind tunnel. Tests were...
Sunshine Skyway Ship Collision Criteria
The 'new' crossing of Sunshine Skyway was born, not only to replace the previous crossings and improve the regional economy but also with increased clearances...
Wind Buffeting of Long Span Bridges with Reference to Erection Phase Behaviour
The balanced cantilever technique for cable-stayed bridge erection can lead to an unacceptable buffeting response at high wind speeds unless the erection scheme is carefully studied. The...
Safety of Long Span Highway Bridges Based on Dynamic Response
This paper consists of an analytical study regarding the dynamic response of highway bridges subjected to heavy vehicle loads, with emphasis on long span low fundamental frequency bridges....
The Far? Bridge?Long Life at Low Costs
The superstructure of the bridge is a steel structure which proved to be competitive compared to the tendered concrete solution, due to simple and rational design both structurally and...
The Applicability of Satellite Altimetry Data to Tidal Models
Different tidal regimes require different data assimilation schemes. In all cases, however, it is better to perform a separate tidal solution before assimilation. For proper assimilation...
General Considerations for Managing Floods and Droughts
Work described at this conference and future developmental work of water resource engineers will best contribute to professional improvement if such work is guided by appropriate objectives....
Missouri River Basin Water Accounting System
A water accounting system was developed for the Missouri River Basin to establish an accurate and acceptable base of information describing water availability and uses, and to provide...
Optimizing a Minimum Instream Flowby
The Commonwealth of Virginia is currently investigating methods to establish minimum instream flow requirements which may be applied to flow allocations statewide. The Crump Creek Reservoir...
Alternative Formulations for Water Quality Management Models
Various model formulations for water quality management are examined herein, each of which involves a somewhat different approach to the problem of determining optimal treatment levels...
A Water Quality Model for Urbanized Drainage Basins
The Virginia Stormwater (VAST) Model has been developed for use on IBM compatible microcomputers to simulate stormwater runoff and nonpoint source pollution. Hydrologic and nonpoint source...
Water Quality Management Through Project Operation
Harry S. Truman Dam, a multipurpose reservoir project, is located on the Osage River in the headwaters of the Lake of the Ozarks. Construction of this project created the potential to...
Spatial Attenuation of Major Pennsylvania Storms
To utilize point estimates for more expansive areas, reduction factors are necessary to account for the attenuation of storm magnitude with increasing area. The spatial attenuation of...
Design Storm Selection for Stormwater Management Master Plans
The design rainfall event is an important performance standard for a stormwater management master plan. A stormwater master plan for Virginia Beach, Virginia, is used as a case study to...
Experiences of the U.S. Army Engineer District, Pittsburgh in Collecting Real-Time Water Control Data
As a result of an ever increasing need to optimize water use, 'Reservoir Regulation' has evolved into what is now known as 'Water Control Management'. In addition to the flood control...
Mesonets--A Solution to Improving Flood Forecasting
Floods continue to cause major destruction annually despite the efforts of Federal water resources agencies. Improved flood forecasts can reduce flood damages and corresponding loss of...
Water Supply Demand Forecast
In this study, estimates of location, quantity and timing of water demands have been investigated for determination of the adequacy of an existing water supply system, the need for additional...
