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...

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...

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...

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....

ENDOW, An Expert System for Screening Environmental Features for Stream Alternations
This paper discusses development of an expert system for Environmental Design of Waterways Projects (ENDOW) by stream alteration specialists who were novices in artificial intelligence....

HEC-1 and HEC-2 Applications on the Microcomputer
The Hydrologic Engineering Center (HEC) has developed versions of the HEC-1 Flood Hydrograph Package and the HEC-2 Water Surface Profiles programs for MS/PC-DOS compatible microcomputers...

Flood Forecasting with Minimal Data
The Corps of Engineers' HEC-1 program has been used with a specialized pre-processor program to provide interim emergency flood forecasting for a 4000 sq mi (10,360 sq km) watershed in...

Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...

An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Legal Misuse of Urban Hydrology Concepts and Regulations for Rural Areas
This paper presents recent observations of the misuse of technical definition, hydrologic concepts, sedimentation engineering principles, and flood control regulations by the legal profession...

Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...

The Design and Construction of the Washington State Convention and Trade Center Over Interstate 5
The Washington State Convention and Trade Center is a 10-level, 1,000,000-square foot facility constructed over Interstate 5 in downtown Seattle. The project spans over three city streets...

Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...

Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...

Lateral Impedance of Contact Pile Foundations
The static and dynamic lateral impedance of pile foundations for which there is continuous contact between the bottom of the pilecap and the underlying soil is investigated. A parametric...

Probability of Facility Damage From Extreme Wind Effects
A probabilistic methodology has been developed to assess the risks of extreme wind induced damage to structures and facilities. The wind effects considered include dynamic pressure, atmospheric...

Uncertainties in Wind Loads Caused by Adjacent Buildings
Mean and fluctuating values of all three moment components caused by wind acting on small-scale models of tall prismatic buildings have been measured. Measurements were made in a boundary-layer...

Risk Assessment for Cladding Panels: An Expert Systems Approach
Risk assessment for structures in the context of wind engineering involves many factors such as wind hazard, the wind sensitivity of the structure and the socio-economic value of the structure....

The Risk of Progressive Collapse of Single-Story Buildings in Severe Storms
The probability of severe damage and progressive collapse of single-story commercial, institutional and residential buildings is examined. Observations of actual damage and the results...

Assessment & Control of Wind Created Risk During Construction
Structures under construction have been damaged by winds. The damaging winds, typically, are much lower than the design wind loads for completed structures. Little guidance is available...
