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...

Expert System for Mixing Zone Analysis of Toxic and Conventional Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software subsystems for the analysis, prediction and design of aqueous toxic or conventional pollutant discharges into watercourses...

Application of Normal Integration Formulas to Bridge Reliability Analysis
Structural reliability analysis often involves extensive integration of complex multivariable functions. Special techniques can be used to reduce this numerical effort. This paper deals...

Time-Domain Dam-Reservoir-Interaction Analysis Based on Boundary Elements
For a reservoir with an arbitrary shape of the upstream face and of the bottom including an adjacent regular part of constant depth extending to infinity, the hydrodynamic-stiffness matrix...

Response of Buried Structure Walls to Earth Penetrating Conventional Weapons
A structural analysis method is presented which accurately models the interface condition between a buried structure and the surrounding soil. During the loading phase, continuity of both...

Combined Finite Difference/Finite Element Analysis for Soil Structure Interaction
A method for the analysis of buried structures subjected to stress transients is presented. The method combines the finite difference and finite element techniques to provide the analyst...

Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...

Comparisons of Full Scale and Wind Tunnel Model Response to Wind of Long Span Bridges
There are several vital reasons for measuring the response of full scale structures to wind and comparing the results to models - both experimental and analytical - employed in design....

Improved Design Procedure for Shallow-Buried Structures to Resist Airblast Loading
Both conventional and nuclear weapons generate airblast loads of sufficient magnitude that structure survival at acceptable cost favors below grade construction. The design of shallow-buried...

Aluminum Orthotropic Bridge Deck Verification
This paper reports tests conducted to evaluate an aluminum orthotropic deck. Approximately 60 welded T-joints with 6061-T6 stems and 5456-H321 plate were subjected to flexural fatigue...

Fatigue Design Criteria for Welded Steel Details
A review of fatigue data and reassessment of the 1983 fatigue specification resistance functions has been conducted. Since the AASHTO specification fatigue resistance provisions were introduced...
