Project Details

Project Description: 

In Japan, many parametric, aerodynamic studies of various deck geometries and details have been conducted and the information from such studies has been used heavily in the development of their Wind Design Guide for Long Span Bridges. In this country, there has been no such systematic study of geometry/details or cataloging of aerodynamic properties. While in the past some effort has been expended to conduct such activities in the Federal Highway Administration Aerodynamics Laboratory, it has been at a very low-level and progress has been slow. The intent of this project is to initiate a more aggressive program of parametric studies to investigate a variety of generic bridge geometries, actual bridge sections, and structural details.

Goals

The objectives of this research are to perform systematic parametric tests on a variety of bridge cross sections and catalog the aerodynamic properties for use by researchers and designers.

Deliverables

Deliverable Name: 
Research Report
Deliverable Type: 
Research report or guidelines
Deliverable Description: 
The deliverable will be a research report containing aerodynamic properties such as force coefficients (lift, drag, and pitching moment), flutter derivatives, critical wind speeds, and Strouhal numbers. The information will be organized for easy reference by researchers and designers. The findings in this report will serve as a basis for later development of draft design criteria.
Deliverable Name: 
Data Archive
Deliverable Type: 
Data
Deliverable Description: 
The test results will also be organized and compiled into an archive for use on future research projects.
