To this end the crushing behavior of single cubical space trusses welded from mild steel bars was studied experimentally. Test specimens made from bars of several different diameters d and lengths L were crushed axially between parallel plates both statically and by the use of a drop hammer. It was found that the energy absorbed per unit mass of energy absorber decreased with the increase in aspect ratio R=L / D in both the static and the dynamic testing, although the specimens tested dynamically were found to absorb nearly twice the energy absorbed by specimens tested statically. Using basic relationships, closed-form equations were developed for predicting the crushing force and the energy absorbed by cubical space trusses. It was shown that the prediction of the crushing force is fairly accurate when compared with experimental results. 2011-09-14T15:08:31Z 2011-09-14T15:08:31Z 2007-06 Article The Journal of the Institution of Engineers, Malaysia, vol. 68(2), 2007, pages 15-20 0126-513X http://myiem.org.my/content/iem_journal_2007-178.aspx http://hdl.handle.net/123456789/13754 en The Institution of Engineers, Malaysia
