Análise não linear geométrica de treliças planas de madeira a partir do método dos elementos finitos posicional

Abstract: <p class="Normal1"><span>Neste trabalho apresenta-se uma metodologia para análise não linear geométrica de sistemas treliçados planos de madeira, a partir de uma formulação posicional do método dos elementos finitos. Dois modelos de treliça são analisados e madeiras folhosas com classe de resistência C60 são consideradas na composição das barras. A formulação do elemento finito é realizada a partir da minimização da energia potencial total, cujo sistema de equações é não linear em relação às posiçõ… Show more

“…The positional formulation based on the Finite Element Method (FEM), conceived by Coda (2003), is an attractive option due to the computational capacity of its approach and the accuracy of the results. This formulation can be adapted to the nonlinear geometric analysis of timber trusses, as noted by Silva et al (2020) and Silva et al (2021).…”
