The Cable Force Identification Of CFST Archbridge And Optimization

In recent decades, our bridges with economic prosperity is rapid development, especiallyfor long-span bridges, it is a glorious period. Among these, the arch bridge on the possession isnot a small proportion. Of these are novel structure, technical complexity, design andconstruction difficult, high technology content. Home and abroad,the middle and lower CFSTarch bridge collapse accident is mostly associated with the health state of the cables. Periodicinspection cables force status is an important basis for arch bridge. The cables are importantcomponents of arch bridge, As bridge construction and post the entire bridge management andhealth monitoring of the most important indicators, it has long been the majority of researchersattention. So how to recognize the cable of the force, especially short cable force, how to usethe cables years to assess health status, how to bridge the impending lesions accuratepredictions and so on, is placed in hanger force identified an important topic in the field. Onlyefficient and accurate identification of the cables force, early detection of bridge issues inorder to avoid harm to innocent people.This research is divided into five parts: The first part is the identification of booms forceresearch also introduced the pros and cons of various identification methods, and describes theconstruction boom common method of cable force optimization. The second part cable forcefrequency method for identifying the status quo and its various restrictions applied to theboom; The third part of the ANSYS APDL-based optimization technology, the boom forparametric modeling to study the structural parameters of the boom itself sensitivity issues,and for the latter cable force recognition software development foundation in theory; fourthpart of the combination Shahe bridge MIDAS finite element model of the boom into the bridgecable force and initial Tension optimized analysis, research in the construction of the bridgeand into a state of structural stress and displacement of the bridge, analyzes the optimalconstruction sequence; fifth part of the main application development software for the cableforce identification test for detection analysis, indicating that the system is capable of ShaheBridge suspender force situation accurately and efficiently identify, to further improve theaccuracy of identification suspender force.
