CRUZ MORENO, Jorge David. Co-rotational beam-column non lineal element evaluation for elastic space frames analysis. Rev. Fac. Ing. UCV [online]. 2011, vol.26, n.3, pp.127-134. ISSN 0798-4065.

This paper shows the results of the analysis of elastic space structures modelled with co-rotational beam-column elements, that takes into account large displacements and rotations of the joints that separate them, from the deformations of the members. This work combines the incremental load method and the procedure of joint orientation matrix, which allow to distinguish and to calculate, in each deformed configuration, the spatial orientation of joints and members. The reported values obtained numerically here are compared with those calculated via other finite element type and with experimentally data.
