The studies carried on during the last three decades with respect to
bamboo have been directed to the physical, mechanic and microstructural
characterization of different species, under static load. The experience has shown
that the houses and buildings constructed using bamboo as structural element
have had good resistance to earthquakes. This work is one of the first researches
to know the bamboo dynamic behaviour. It was studied the dynamic properties of
systems made of bamboo with the species Dendrocalamus Giganteus and
Phyllostachys Áurea. The researched dynamic properties correspond to values of
damping and natural frequencies of vibration for each specie, which were gotten
through free vibration and modal tests. With the intention to study the influence of
the storage period in the dynamic response of the material, for culms of
Phyllostachys Áurea specie, five variables were considered: culms without
treatment cut in March of 2008, without treatment cut in May of 2007, without
treatment cut in 2001, with treatment on fire (blowpipe) cut in March of 2008 and
with treatment on fire (blowpipe) cut in May of 2007. Furthermore, for the two
species was determinate the variation of damping in function of variation of the
quantity of fibers along the material thickness.
