Abstract


Bridge structural design and calculations do not usually consider the joint force of the whole layer with the main structure , and thus ignored the overall layer structure mechanical behavior . With the the deck pavement improvements in technology and the application of new materials , improved the overall durability of the layer , the whole layers involved in the force structure , and thus overall layer structure calculations should consider the impact of for most bridges . Explicitly consider the effects of the overall layer of prestressed concrete box girder bridge force performance , according to the characteristics of precast box girder deck as a whole layer under the action of Composite Structure by finite element program to simulate the mechanical characteristics and combined with real bridge load test a systematic study of this issue . 1, respectively, without a whole layer of prestressed concrete simply supported box girder , the overall layer anchorage prestressed concrete box girder , the overall layer anchorage prestressed concrete box girder finite element analysis , study three types of members of the force characteristics , comparative analysis of the mechanical behavior of the deck as a whole layer of the main beam . Variable continuous prestressed concrete simply supported continuous beam under the influence of the the overall cascading cooperation with the finite element analysis of prestressed concrete continuous box girder under vertical loads , and to explore consider the the Cascading overall cooperation with the continuous box girder internal force distribution law . 3 , prestressed concrete box the Liang Qiaojing of which is set out test, test 4 test conditions most unfavorable section of box girder stress and deformation , to make assessment of prestressed concrete box girder bridge the mechanical properties of the whole bridge . And with finite element software to calculate the stress and deformation of the test conditions the whole bridge , comparison, analysis and test test value of the overall layered aggregate effect of the impact force of the entire bridge . 4 , with engineering examples , explore the overall stacked together effect in engineering and make recommendations accordingly .
