Since all of these conditions have the chance to damage bridge structure, we calculate the particular wind speed and magnitude that will maximize the reaction. To check if the theory works well, a bridge model is set up and analyzed in SAP2000 and the results are compared with one from mechanics theory. A cable-stayed bridge from Hong Kong is selected for analysis. After we compare the bridge reaction by different methods, we find that theory of aerodynamics can provide reasonable result. However, we're still looking for a better performance from the bridge and improved motion control. Thus, to optimize the structure, design of a tuned mass damper is included as well. Summarily, wind effect on long span bridge is predictable and could be well controlled by various means based on the analysis in this thesis.","abstract_html":"This thesis has studied different types of reactions of long span bridge under wind load, such as vortex shedding, flutter and buffeting.
