The Force Analysic Of Frame Structure Of Isometric Column Grid In Uneven Settlement Of Foundation

Differential settlement of the Foundation is the major cause of damaged buildingstructure, uneven ground settlement cracking in XI ’ an induced by severe. In order to preventdamage caused by activities of the ground fissures to the new building, Shaanxi Provincialminimum avoidance distance of the local statutes provides for buildings. In-depth analysis ofthe cracks in the area of construction safety has s important practical significance to determinesecurity Lien.Zhou Yangyang and Liu Bohua have an analysis on cracks in Gallery of framed structuresunder the influence of internal forces and deformation.In this paper, the research is onequidistant cylindrical NET frame structure, study on application of combination of theoreticalanalysis and finite element analysis method, through the elastic analysis on the structure of thedifferent collision avoidance distance, equidistant cylindrical NET frame structure research ofinternal forces and deformation.Predecessors have analyzed the internal forces and deformation under the influence ofcrack in the gallery-style frames. This paper uses50A of the future settlement curve,establishing a total of4,6,8, and span,6m,8.4m, six equidistant cylindrical NET framemodel structures. We use displacement method simulation of taphrogenic differentialsettlement and the SAP2000analysis of different layers, different span and collision avoidancedistance raster columns taphrogenic differential settlement under the framework of thenetwork of internal forces and deformation. After the analysis of the internal forcecombination, equidistant columns with different span network framework in7degree(0.1g),8degree(0.2g) internal forces and deformation of the district.Through the collation of results analysis, the article gets the taphrogenic differentialsettlement under the action of different heights, different spans of internal force changing ruleof equidistant cylindrical NET frame structure, gives the causes of uneven settlement of totalinternal force and internal force (combination of dead load, live load and earthquake) ratiotables. After the combination of internal forces and different intensity of different spans,equidistant cylindrical NET frame structure in a variety of collision avoidance distance withinthe structure’s internal force and displacement and comparative analysis of structure internalforce and displacement of ordinary venues, moved down specification for frame structureunder a reasonable possibility of collision avoidance distance.Research result of this article has some significance reference for Ley lines on the site ofequidistant cylindrical NET frame structure design.
