“…The whole procedure is repeated until the values of the reactions converge or the settlements are obtained between two consecutive iterations within a desired tolerance. More details about the methodology adopted can be found in Santos [10]. In this paper, the convergence criterion presented in Eq.…”

“…This mechanism is called soil-structure interaction (SSI) and has been the topic of many studies (Meyerhof [4], Chamecki [5], Goshy [6] and Gusmão [7]). Testoni [8 and 9] and Santos [10] discussed SSI in reinforced concrete wall buildings. Despite recent research and the design code, advances are still needed in knowledge regarding the reinforced concrete wall building behavior and their analysis models.…”

This paper presents a study of the effects caused by soil-structure interaction in reinforced concrete wall building on shallow foundation. It was verified the influence of displacements of supports on the redistribution of internal forces in the structural walls and in the redistribution of loads on the foundation. The superstructure was represented by shell finite elements and the soil-structure interaction was evaluated by iterative methods that consider the stiffness of the building, the soil heterogeneity and the group effect of foundation elements. An alternative model that considers the soil-structure interaction is adopted and the concrete walls are simulated by bar elements. The results indicate that the soil-structure interaction produces significant changes of the stress flow, with larger influences on the lower walls, as well as a tendency of settlements standardization and load migration to supports with smaller settlements.

“…As diferenças são elevadas do ponto de vista de projeto e, por isso, não devem ser desprezadas no dimensionamento dos elementos estruturais. (TESTONI, 2013, p.178) Neste trabalho, deu-se continuidade às investigações realizadas por Testoni (2013), e complementando o escopo das investigações realizadas por Santos (2016), aprimorando com a consideração das ações evolutivas ou sequência construtiva, lançando mão da validação do modelo Yagui, com foco na modelagem refinada das paredes (em elementos finitos de casca), do pilotis, blocos e estacas (em elementos finitos de barras), e do solo (em elementos finitos sólidos).…”

A análise das estruturas, independentemente da sua complexidade, é de grande valia na formação acadêmica e profissional do engenheiro, uma vez que isso impactará em todo projeto que este estiver a frente. Esta pesquisa objetiva a determinar, pelo método das forças, os diagramas de esforços solicitantes de momento fletor e cortante de um elemento estrutural e compará-los a softwares automatizados, utilizando de método quantitativo, documental, bibliográfico e simulação de software. A amostra corresponde a uma viga hiperestática de concreto armado (viga V1) em um edifício unifamiliar, que possui 4 apoios: 1 apoio de segundo gênero na extremidade esquerda e 3 apoios de primeiro gênero, sendo 1 na extremidade direita e 2 como apoios intermediários. A análise tem foco nos resultados obtidos em cada um dos casos encontrados a partir do Sistema Principal da viga escolhida. O resultado aponta que o método das forças para determinação e resolução da viga mostra-se limitado, pois por se tratar de um método simplista, tem grande chances de ocorrer falhas na obtenção dos valores corretos dos gráficos de esforços, o que poderia comprometer o dimensionamento correto da viga de concreto armado, no que tange as suas armaduras.
