Numerical and experimental evaluation of masonry prisms by finite element methodAvaliação numérico-experimental de prismas de alvenaria estrutural pelo método dos elementos finitos Abstract ResumoThis work developed experimental tests and numerical models able to represent the mechanical behavior of prisms made of ordinary and high strength concrete blocks. Experimental tests of prisms were performed and a detailed micro-modeling strategy was adopted for numerical analysis. In this modeling technique, each material (block and mortar) was represented by its own mechanical properties. The validation of numerical models was based on experimental results. It was found that the obtained numerical values of compressive strength and modulus of elasticity differ by 5% from the experimentally observed values. Moreover, mechanisms responsible for the rupture of the prisms were evaluated and compared to the behaviors observed in the tests and those described in the literature. Through experimental results it is possible to conclude that the numerical models have been able to represent both the mechanical properties and the failure mechanisms.Keywords: numerical simulation, concrete prisms, prisms failure modes.No presente trabalho desenvolveram-se ensaios experimentais e modelos numéricos capazes de representar o comportamento mecânico de prismas confeccionados com blocos de concreto comuns e de alta resistência. Foram realizados ensaios experimentais de prismas e, para a análise numérica, adotou-se como estratégia de modelagem, a micromodelagem detalhada, onde cada material (bloco e argamassa) foi representado por suas propriedades mecânicas. A validação dos modelos numéricos foi realizada com base em resultados experimentais realizados. Verificou-se que os valores obtidos numericamente de resistência à compressão e módulo de elasticidade diferem 5% em relação aos valores observados experimentalmente. Ainda foram avaliados quais os mecanismos responsáveis pela ruptura dos prismas, comparando-se tanto com o comportamento verificado nos ensaios, quanto com os descritos na literatura. Por meio dos resultados experimentais conclui-se que os modelos numéricos foram capazes de representar tanto as propriedades mecânicas quanto os mecanismos responsáveis pela ruptura.Palavras-chave: simulação numérica, prismas de concreto, modos de ruptura prismas.
