The3D Simulation And Analysis For The Bridge Based On ABAQUS

The big bridge of N is a large highway cable-staged bridge of concrete.Due toIncluding the advanced design techniques and construction techniques, thecable-staged bridge needs more considerable money. Say for the big bridgecontaining high techniques and high devotion, it is essential to maintenance andprotect it for its working well. Therefore, the topic for the big bridge’s strengthanalysis can check it whether it works well as designer’s planed proposal.ABAQUS is an advanced general-purpose finite element system, the softwarestructure of solid and structural mechanics, numerical calculation and analysis, inparticular, is capable of controlling a very large problem and simulate the influence ofnonlinear There are two main analysis module in ABAQUS: ABAQUS/Standardprovides a common analytical ability; applications of ABAQUS/Explicit is time forthe dynamic simulation of the explicit integral. Use of the ABAQUS finite elementanalysis of mechanical strength of the N bridge to provide accurate and usefulnumerical reference for the engineering design and safe operation into a bridgemaintenance. N Bridge in ABAQUS three-dimensional simulation, simplifiedmechanical bridge model in ABAQUS, and then use the functionality of the softwarehas loaded, a realistic simulation. At the same time the mechanism of the bridgeunder the combined effect of the three loads and the initial displacement, the elasticanalysis and deformation analysis. This article using the elastoplastic damage modelfor concrete mechanical analysis, numerical results were compared with experimentalresults, concrete injury trend. While taking advantage of the numerical resultsobtained on the role of bridge load deck and stress changes calculated; verify that thedesign meet the requirements of internal force combinations and arrive at the projectonly because of improper construction, resulting in cracks in the concreteconstruction.The computing using the intensity analysis of cable-stayed bridge is a non-linearcalculation method, the elastoplastic damage model of concrete mechanical analysis,and provides valuable reference data for the design and bridge maintenance. Thesame time, the economic input of the cable-stayed bridge in the ABAQUSthree-dimensional simulation, the nonlinear numerical analysis, the economic cost ofthe engineering test of the relative entities, very little, save a considerable economicinput. In addition, as a practical engineering design and simulation applications ofcomputing to provide reference data in this paper the following conclusions: the roleof bridge load, calculate the deck as well as the stress changes; and come to meet therequirements of the design, but due to improper construction, resulting in theconstruction of concrete cracks. Paper the strength of the static load on thecable-stayed bridge, does not do dynamic load plastic analysis of simulation andpractical than a certain amount of deviation. This is where we need to improve infuture studies.
