“…The analysis results in terms of load versus deflection, strain in the longtitudinal steel bars, and cracks were compared with the experimental results. It was found the finite element analysis results are in close agreement with the experimental results of RC pile caps (Sam and Iyer 1995). Souza et al 2007 conducted a non-linear finite element analysis of RC pile caps under generic loading.…”

Reinforced concrete (RC) Pile cap, a thick reinforced concrete block, is constructed to provide a connection between a structure and multiple single piles. In the existing design methods, the behavior of RC pile cap is usually considered as a rigid body and resulting forces or reactions on piles are assumed equal. However, in actual conditions, there is a possibility of bending of pile cap and unequal reactions or forces on piles. This study represents a detailed finite element analysis of RC eight-pile cap by using a computer program ATENA. ATENA serve as rational tools to explain the behavior of RC structures. Research parameters included different types of loading conditions, analysis types such as linear and non-linear, support conditions, length of pile, strength of concrete and thickness of pile cap. The finite element analysis results indicate that the behavior of RC pile cap is not a rigid body and resulting forces or reactions are unequal. Also, it was observed that, support conditions, analysis type and thickness of RC pile cap had a significant effect on the global behavior of RC pile caps.

“…In order to verify if the adopted models for the numerical analysis of the two pile caps show correct behavior trend, comparative analysis of experimental tests and numerical simulations of several researchers. In this work, it will be presented the results of the comparative numerical analyses of the tests performed by Mautoni [15] and Adebar et al [16] and of the numerical simulation developed by Sam & Iyer [17]. In Delalibera [5], it can be observed the rest of the comparative analyses performed and more details of the numerical analyses developed.…”

“…In the numerical simulation, these forces were 501,94 kN and 2589.74 kN. Figures [12], [13], [14], [15] e [16] showed the correlations obtained between the numerical and experimental results and [17]. The piles caps were simulated with arrangement reinforcement distributed in mesh and on the piles.…”

The structural behavior of pile caps with sockets embedded is influenced by interface of column-socket, which can be smooth or rough. With intent to analyze the behavior of two pile caps with embedded socket, considering the friction between the column and the socket, with eccentric normal load, the numerical simulations were carried out, using a program based on the Finite Element Methods (FEM). In the numerical analysis the non-linear behavior of materials was considered, also the friction between the column and the socket. It was considered perfect bond between the reinforcement and the concrete around. It was observed that the embedded length is preponderant factor in the structural behavior of the analyzed element.

“…As conclusões de Iyer e Sam (1995) contrastam com as conclusões de Blévot e Frémy (1967) e de Taylor e Clarke (1976) no que diz respeito ao melhor arranjo de armadura. Nos resultados experimentais, a força média de ruína para os blocos com armadura em forma de malha e com armadura sobre as diagonais foram respectivamente 10% e 8% superior à obtida no bloco armado segundo os lados.…”

“…Mas, percebe-se que o ângulo de inclinação das bielas dos modelos ensaiados por Iyer e Sam (1995) é de 54,2°, próximo ao valor máximo indicado por Blévot e Frémy (1967) de 55° para o uso do Método das Bielas com segurança. Considerando que o tirante idealizado situa-se sobre as estacas, pela lógica do Método das Bielas, é conveniente que haverá maior eficiência quando houver maior concentração de armaduras nessa região, todavia, ao se aumentar o ângulo de inclinação das bielas ocorre uma redução da força de tração no tirante que pode explicar os resultados obtidos por Iyer eSam (1995).…”
