Effect of windshields on the aerodynamic performance of a four-box bridge deck
Xi Chen and Elena Dragomirescu

 
Abstract
    A new type of bridge deck section consisting of four-box decks, two side decks for vehicular traffic lanes and two middle decks for railway traffic, has been experimentally investigated for determining its aerodynamic properties. The eight flutter derivatives were determined by the Iterative Least Squares (ILS) method for this new type of four-box deck model, with two windshields of 30 mm and 50 mm height respectively. Wind tunnel experiments were performed for angles of attack
 
Key Words
    flutter derivatives; four-box bridge deck; aerodynamic coefficients; wind tunnel tests
