For a long time, structural engineering has been searching for the improvement of numerical methods and more accurate analysis. Currently the most applied and known numerical method for structural analysis structures is the Finite Element Method. Recently, Bonet et al. (2000) and Coda (2003) presented one formulation based on the nodal positions, so called positional
formulation, which is robust and simple to implement. In this paper, the finite element method in positional formulation is used
for frames structures analysis considering the effects of geometric nonlinearity
and inertial forces. The main purpose is to implementation of non-uniform BSplines
as shape functions for the positional formulation. B-Splines, beyond possessing attractive properties, such as positivity,
smoothness and local control, are standard CAD functions. Therefore, its use in an efficient program for structural analysis makes easy the integration between design and analysis, reducing time and eliminating errors with mesh generation in the finite element analysis environment. |
