Wind Tunnel Aeroelastic Model Study of the Baytown Bridge (Steel Alternative)
Analytical and full bridge aeroelastic model studies performed to assess the aerodynamic stability of the steel alternative Baytown Bridge over the Houston Ship Channel are described....
Wind Tunnel Investigation of a Twin Deck Suspension Bridge
Wind tunnel measurements of the response of a twin deck suspension bridge to dynamic wind loads are presented. The investigation was concerned with the determination of the deck response...
Aspects of Wind and Earthquake Dynamics of Cable-Stayed Bridges
In the course of dynamic analysis of long-span cable-stayed bridges for the effects of earthquake and wind, a number of observations have been made that may be of interest to designers....
Analysis and Design of Wind- and Earthquake-Resistance of an S-Curved Cable-Stayed Bridge
Just recently, in January of 1987, the first S-curved cable-stayed bridge in the world has been completed as a part of Metropolitan Expressway's Katsushika-Edogawa Route in...
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...
Furrow Modeling with Variable Hydraulic Characteristics
A zero inertia furrow irrigation model was developed to run on an IBM-compatible micro-computer. The depth gradient term of the momentum equation is approximated by averaging over the...
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....
Are Soil Moisture Accounting Models Needed for the Real Time Forecasting of River Flows?
The difficulties inherent in using conceptual rainfall-runoff models in conjunction with filtering techniques, for the real time forecasting of river flows, are reviewed. The issue of...
The Great Lakes Large Basin Runoff Model
The Great Lakes Environmental Research Laboratory (GLERL) developed its Large Basin Runoff Model (LBRM) specifically for modeling runoff and moisture storages in the large river basins...
Probabilistic Forecasts of Continued High Great Lakes Water Levels
Existing projections of Great Lakes water levels over the next several years do not consider how meteorologic variability affects the hydrologic processes (basin runoff, overlake precipitation,...
Water Supply Analysis for the Milk River Basin, Montana
The U. S. Bureau of Reclamation's Milk River Irrigation Project provides water for 55,000 ha of irrigation in the Milk River basin of Montana. The project includes an interbasin...
Estimating Firm Yield and Reliability of Small Reservoirs on Ungaged Streams in North-Central Montana
A reservoir-operation algorithm utilizing a sequence of monthly streamflows from a lag-one Markov model is proposed for estimating firm yield and reliability. The reservoir-operation algorithm...
