In 2010 , the World Expo held in Shanghai, China , the World Expo theme of \This also means that the world urbanization is accelerating, and urban construction as the carrier of the urbanization process is even more important . City bridge is an indispensable part of urban construction , modern city bridge towards landscape coordination , people-oriented , broad bridge width direction of development . This thesis is on North Road Liuyang River Bridge, the main bridge in Changsha Mars research background , combined with the characteristics of the development of the modern city bridge , the use of finite element theory knowledge and calculation software , mainly to study the contents of the following aspects of its design analysis : 1, people , cars Branch steel box arch bridge structure structure and mechanical characteristics of the analysis , and applications in the Liuyang River Bridge . Liuyang River Bridge space finite element static analysis . On this basis boom , beams, bridge decks and other structural details were fine finite element analysis , and compared with the experimental results . Liuyang River Bridge space dynamic characteristics of the finite element analysis , and comparative analysis and modal experiment results . 4 , Liuyang River Bridge in the earthquake response were calculated and analyzed using the response spectrum method . Finally , according to the results of the analysis of each chapter summarized the force characteristics of the vehicles and branch structure steel box arch bridge , bridge design reference for the same type .
