Abstract


Navigable Bridge of Qingdao Bay Bridge Red Island research background, combined with our large span steel box girder construction practice , by the finite element analysis , a systematic study of the steel box girder force performance . Finite element space truss model using the finite element software MIDAS , the cable-stayed bridge overall force performance analysis ; use of a large-scale general-purpose finite element software ANSYS , the cable-stayed bridge overall stability analysis . Red Island navigable bridge tower anchorage anchorage system with steel anchor plates , steel - concrete composite structure using ANSYS finite element analysis of the cable-stayed bridge anchorage zone , different load case Pylon in contact with the base at and the base of each cross-section of the force . Anchorage Zones in key parts of the cable-stayed bridge , with a the anchor box-type anchor structure in the web outside of welded box -type structure , cable anchor anchor box pressure board , from the cable-stayed passed to the huge cable force dispersed throughout the main beam section on the basis of the analysis of the overall performance of a local analysis , the use of ANSYS for cable-stayed bridge on the Anchorage area segment by force . Establish the model of the steel box girder sections , two, three system stress loads under the most unfavorable conditions force , obtained local stress distribution and overall displacement law , and did not exceed the local maximum stress the material's yield strength. Steel box girder finite element analysis , recommendations for the design of the cable-stayed bridge . Red Island navigable the hole bridge tower anchorage steel anchor plate anchorage system , the structure is novel , the first use . The finite element analysis and calculation , understand the anchorage zone stress mechanism and load transfer , and provide a reference for future cable-stayed bridge in the use of the bridge construction and promotion .
