The Design of Stays for Cable Stayed Bridges
Much of the R & D work done in the development of details for the modernized form of stayed girder bridges has been contributed by those practicing in the field of prestressed...
Wind Buffeting of Cable-Stayed Bridges During Construction
Some of the dominant loadings on a cable-stayed bridge during construction are a result of the non-uniform vertical and horizontal gust forces on the deck and the associated dynamic response...
Development of a Double Tee Structural System for Highway Bridges
The fully precast, prestressed double tee beams are tied together by transverse post-tensioning through simple grout filled V-joints. The system provides for complete transversal continuity...
Innovative Approaches to Bridge Pier Foundation Design
As a part of a Value Engineering change proposal the pier foundations for the US-31 bridge over the St. Joseph River and floodplain near Niles, Michigan were re-designed. The varying soil...
Design of Bridge Piers Against Ship Collision
Design rules for unprotected bridge piers, using uniform safety requirements, are proposed. The selection of an appropriate design vessel is based on a risk assessment model which uses...
Micro=Lam? LVL: A New Alternative for Timber Bridges
Laminated veneer lumber (LVL) provides a unique opportunity to obtain large structural members from ever-smaller trees. It provides the added benefit of high treatability. This paper explains...
Prediction and Control of the Wind Response of Long-Span Bridges with Plate Girder Decks
The aerodynamic stability of plate girder decks and methods of improving it are discussed. The selection of an appropriate design wind speed for flutter is reviewed including the effect...
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....
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...
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...
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....
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...
Design of Seepage Fields for Stormwater Disposal
Stricker Pond is a shallow twenty-acre kettle hole pond in south-central Wisconsin. The pond receives runoff from a closed watershed that is rapidly undergoing low density residential...
Maximizing Utility of Interfaces for Hydrologic Models
From the time a watershed layout has been determined, there is sufficient information for a computer to generate a command sequence for hydrologic simulation. Recognizing this fact, an...
Site Hydrology and Basin Design Using Spreadsheets
The Soil Cover Complex Method which was developed by the Soil Conservation Service is a commonly accepted method of evaluating site hydrology. The solution of this method is facilitated...
Micro-Illudas for Urban Drainage Design
The Illinois Urban Drainage Area Simulator (ILLUDAS) was developed at the Illinois State Water Survey in 1969 and has been available for use on mainframe computers since 1974. An enhanced...
