Abstract The long span cable-stayed bridges are considered as a modern form of the bridges which are both economical and aesthetic. In the past of few decades construction of long-span bridges was used widely in crossing wide water. The study of wind effect is considered main items to design the type of bridges. Therefore, the importance of the wind tunnel test measured the flutter critical wind speed. Some of the researchers concluded from this test some of empirical equations to calculate the flutter wind speed. The main objective of this research is comparing some of equations with each other. These empirical equations applied to the three dimensional finite element analysis of cable-stayed bridges. The conclusion results of the research are compared to the empirical equations with each other by using the frequencies of three bridges model shapes, that was modeled on the SAP program |
