• Abstract:
  A unified body of theory is presented to cover the main phenomena of the wind-induced responses of long-span bridges. The methods discussed depend strongly upon experimental data extracted through aeroelastic tests of bridge deck section models. Much of the background material stems from Report No. FHWA-RD-75-115: "Recent Methods in the Application of Test Results to the Wind Design of Long, Suspended-Span Bridges", Federal Highway Administration, Offices of Research and Development, Washington, D.C. (October 1975). The sections of the present report are: I. Introduction and Overview; II. The Background Literature; III. Analytics of the Flutter Problem; IV. A Vortex-Shedding Model in the Bridge Context; V. Parameters Affecting Long-Span Bridge Buffeting Susceptibility; VI. Conclusions. The Report contains calculated examples of all phenomena discussed.
