Research on the structural verification of the"butterfly arch continuous beam"composite system
Due to its innovative construction and meeting the development needs of bridge aesthetics,irregular arch bridges have become landmark buildings in various regions in recent years.Due to the complex design and structural stress system of irregular arch bridges,it is necessary to study the construction process and reasonable completion status of arch bridges.In response to the complex problem of the"butterfly arch continuous beam"com-posite system bridge structure,in order to ensure the stability of the structure during the construction and operation phases,the construction sequence and reasonable completion status of the butterfly arch continuous beam composite bridge were studied,and the structural stability and applicability of the"butterfly arch continuous beam"composite system structure were verified.Using the method of structural verification,check whether the parameters such as deflection and stress during the construction phase meet the stability requirements,analyze the ultimate and normal limit states of the bearing capacity during the operation phase,and verify the structural deflection to ensure the sta-bility and applicability of the structure.The management data of the entire life cycle from construction to operation has been formed,which can be used to guide the design and construction of the bridge,solve the problem of unrea-sonable distribution of internal forces in the suspension rods,improve the structural safety redundancy,and provide reference for the design and construction of such butterfly beam arch composite bridges.
