O modelo proposto simula o comportamento da parede utilizando exclusivamente elementos finitos de barra, compondo, assim, um p?rtico equivalente. A valida??o foi realizada sob dois aspectos: primeiramente, mediante estudo de diversos pain?is planos gen?ricos, confrontando os resultados obtidos do modelo de p?rtico equivalente com os de um modelo de refer?ncia, o qual utiliza elementos finitos de casca na discretiza??o das paredes e, numa segunda etapa, comparando com os resultados do modelo experimental de Rosenhaupt. As an?lises consideraram o comportamento el?stico linear para os materiais e consistiram basicamente na avalia??o dos deslocamentos verticais e dos esfor?os nas vigas de apoio, bem como das tens?es na base das paredes. Foram avaliados tamb?m, a partir de modelagem plana e tridimensional de algumas paredes de um projeto real, aspectos importantes da intera??o parede-viga, tais como: presen?a de aberturas de portas e de janelas, dispostas em qualquer posi??o; condi??es de apoio e vincula??o das vigas; interfer?ncias das amarra??es entre paredes; considera??o da a??o do vento. As an?lises dos resultados alcan?ados evidenciaram a efici?ncia da modelagem proposta, em raz?o de apresentarem aspectos muito semelhantes na distribui??o de tens?es e de esfor?os, sempre com intensidades um pouco maiores do que as dos modelos de refer?ncia e experimental. / The developed study proposes a new computer modeling efficient and easy to apply in usual project situations to evaluate the interaction between masonry panels and support structure. The proposed model simulates the behavior of the wall exclusively using frame finite elements, thus compounding an equivalent frame. The validation was performed in two ways: firstly, through the analysis of various panels of generic plans, comparing the results obtained from equivalent frame model with the ones from a reference model, which uses shell finite elements in discretization of the walls? and in a second step, comparing with the results of the experimental model of Rosenhaupt. The analyzes considered the linear elastic behavior for materials and consisted basically in the evaluation of vertical displacements and efforts in support beams, and tensions at the base of walls. Was also evaluated, from flat and threedimensional modeling of some walls from a real project, important aspects of the wall-beam interaction, e.g.: the presence of openings of doors and windows, arranged in any position? conditions of support and linking of beams? interference of moorings between walls? and consideration of wind action. The analysis of the achieved results demonstrated the efficiency of the proposed modeling, since they have very similar aspects in the distribution of stresses and efforts, always with intensities slightly larger than those of the reference and experimental models.
