The structure is an aluminium truss used at exhibitions. Their are 4 50dia tubes forming the beam/truss separated by lattice bracing. Tubes are spaced at 470mm thus forming a square shaped truss. I have read the paper suggested but it only provides J for an individual CHS. I'm looking for J...
Am trying to calculate Torsional Constant for an aluminium tubular truss. The truss is made up of 4 50dia tubes setout in square shape 470mm apart. Tubes are separated by bracing struts. Can anyone provide advice?
