摘要：

Periodic lattice structures such as the large space lattice structures and carbon nanotubes may take the extension-transverse shear-bending Coupled vibrations, which can be well represented by the extended Timoshenko beam theory. In this paper, the spectrally formulated finite element model (simply, spectral element model) has been developed for extended Timoshenko beams and applied to some typical periodic lattice structures Such as the armchair carbon nanotube, the periodic plane truss, and the periodic space lattice beam.
