Internal Force Analysis Of Multiple Shear Wall In Ground Fracture Area

Ground fracture in city construction has caused severe damage effect particular allkinds of buildings in the ground fracture area. There is few research work especially shearwall buildings in the ground fracture area, so in this paper, multiple shear wall in the groundfracture area are studied.At the basis of the coupled shear wall that Hu Zhijun and Xu Zhen Qi studied,according to the predictably settlement model given by Zhouyangyang, elastic-plasticanalysis for multiple shear wall structure were carried out by the finite element analysissoftware, study of the structure state of different limb shear wall at different required securedistances in ground fracture area.ANSYS12.0finite element analysis software is used to establish two limbs in this paper,three limbs and four limb the separated finite element model of reinforced concrete shearwall, the uneven ground settlement will be applied to the model by a given bearing forceddisplacement and performed finite element analysis. Firstly, the model is only affected theresponse of the structure by the influence of uneven ground settlement, Sorting out themodel of internal force, deformation, stress, fracture, etc, finding the greatest impact on thestructure of the internal forces from a different avoidance distance and found the responseand shear structures limb have not directly related to the number of walls. Again comparethe internal force of shear wall structure alone under the uneven settlement of the groundwith that of combination of internal forces under common field. the ratio of the table willlink the uneven settlement of the ground with common field, you can easily find Thestructure of the total internal forces in ground fracture area. Besides paper also put forwardsome suggestions for engineering reference shear walls. Therefore, to study the impact ofinternal forces in ground fracture area on the building structure has a certain significance forenriched theoretical research and rationalize engineering design in ground fracture area.
