“…To discretize the wall in the SHELL model, four-node quadrilateral shell finite elements (Shell-thin) were used with dimensions of 0.4mx0.4m and 0.12 thickness, as shown in Figure 2. Braguim [2] made comparisons between meshes with 0.2mx0.2m and 0.4mx0.4m dimensions and concluded that the differences in the results are practically non-existent. In this paper, a prior analysis was carried out to evaluate the influence of the mesh discretization on the results of the study building.…”

“…Dependendo da inclusão ou não das vinculações laterais são formados um ou dois planos de flexão na parede (Figura 2.4). Figura 2.4 -Planos de flexão e vinculações -Adaptado de Braguim (2013) Os estudos realizados nos trabalhos de Saheb e Desayi (1989Desayi ( e 1990 serviram como base para o equacionamento utilizado pelo código americano ACI318 (American concrete Institute, 2011) para paredes de concreto submetidas a esforços normais.…”

“…Pode-se concluir pela análise do estudo de Nunes (2011) que o uso de elementos planos é necessário apenas nos pavimentos afetados pela deformação da base das paredes. Braguim (2013) comparou a análise estrutural de um edifício de parede com 16 pavimentos em um modelo de pórtico tridimensional com um modelo composto por elementos de membrana (Figura 2.10). O estudo realizado considerou os edifícios sobre apoios fixos.…”
