“…Nine 20-node elements with fifteen integration points are used in the analysis. In Figure 8, the central displacement response of the concrete slab is determined and compared with the results obtained by Ayyad (2003) and by Haido et al (2010) who used layered shell elements. Results are in agreement with those obtained in the previous references.…”

ResumoNesse trabalho, apresenta-se um modelo numérico para a análise não-linear estática e dinâmica de vigas, placas e cascas de concreto reforçado. Sendo assim, procedimentos de análise, baseados na teoria da plasticidade e com monitoramento de fissuração, são desenvolvidos. Elementos finitos de casca degenerada de 9 nós são usados na análise estática, enquanto elementos finitos de 20 nós são considerados para a análise dinâmica. A lei constitutiva do concreto é acoplada a um modelo sensível à velocidade de deformação, para se terem em conta os efeitos produzidos para altas velocidades de deformação. O procedimento de Newmark é adotado para a integração no tempo do sistema não-linear de equações. Considera-se que o aço de reforço está perfeitamente distribuído e aderido ao concreto, sendo esse representado por elementos finitos de membrana. Vários exemplos são solucionados com o presente modelo numérico e os resultados obtidos são conferidos com os resultados de outros autores. Para todos os casos, o caminho de falha, o carregamento de colapso e o mecanismo de falha são reproduzidos com suficiente precisão. Palavras chaves: Estruturas de concreto reforçado, método dos elementos finitos (MEF).

“…The main objective of this work is to verify the application of the FDEM to nonlinear analysis of reinforced concrete slabs using the Damage Model of Mazars [18]. Another nonlinear models, based at experimental results, has been used to describe the stress-strain behavior of concrete [22][23][24] but the application of Mazars´s Model showed a good performance to analyze of reinforced concrete beams [25][26] and requires few experimental parameters. Two reinforced concrete slabs evaluated experimentally by Taylor et al [27] and McNeice [28] were used to validate the proposed model.…”

This work presents a model to predict the flexural behavior of reinforced concrete slabs, combining the Mazars damage model for simulation of the loss of stiffness of the concrete during the cracking process and the Classical Theory of Laminates, to govern the bending of the structural element. A variational formulation based on the principle of virtual work was developed for the model, and then treated numerically according to the Finite Difference Energy Method, with the end result a program developed in Fortran. To validate the model thus proposed have been simulated with the program, some cases of slabs in flexure in the literature. The evaluation of the results obtained in this study demonstrated the capability of the model, in view of the good predictability of the behavior of slabs in flexure, sweeping the path of equilibrium to the rupture of the structural element. Besides the satisfactory prediction of the behavior observed as positive aspects of the model to its relative simplicity and reduced number of experimental parameters necessary for modeling.
