Resumo: | A method for the calculation of the initial tangent stiffness and the ultimate secant stiffness of flexible connections was presented. Local flexibilities, in elastic phase, of rigid connection where evaluated.It was proposed the utilization of node models, in plane frame structuralanalysis, in order to make possible the consideration of stiffness, in flexible connections and/or in rigid connections. A computer program was developed to automatize the generation of the node models in the structures to be analyzed. So, it became possible that the influence of the connections, treated as semi-rigids, could easily be considered in the structural analysis. Two examples of utilization of the program were presented. The responses of conventional structures (simple support nodes and rigid nodes) and structures with node models were compared. |
