Completion and development of reliable analytical models using finite element method could help\r\ninvestigation and prediction of the actual structure response results. Analysis of each model in finite\r\nelement software need meshing that computer results are dependent specific to geometry and\r\ndimensions of the elements, calling mesh dependence. Finding a strategy for independency of results\r\nto meshing is tangible. For the mentioned purpose and also to investigate the role of finite elements\r\nmeshing in flanged shear walls, finite element software was used. Different meshing of shear walls\r\nwhich tested by Vecchio and Palermo analyzed and studied. Finally, and after calibration, optimum\r\nforms and dimensions recommended. As an illustration, an idea presented, which indicates by using\r\nthat, flanged shear wall could be analyzed more carefully in ultimate strength and ductility. The results\r\nof this analysis showed that the results of squared mesh are closer to the fact. For example, this type of\r\nmeshing 6% error in ultimate strength and ductility in accordance to lab Specimen, presented the closer\r\nresponses. Furthermore, investigation on the optimum size of the mesh showed that if the mesh has\r\nthe same size of the thickness of the connecting element (Shear Wall Web), the results will have very\r\nhigh accuracy. For example, squared meshes with same dimension of meshes equal to web thickness,\r\nrather than those with half dimension of that led to 1% of lateral resistance, which is closer to\r\nexperimental test.
