There is provided a box structure having upper and lower composite integrated sandwich panels, for carrying load. The panels have facesheets sandwiching one or more core portions and dense packs adjacent the one or more core portions oriented in an axial direction. The box structure further has a plurality of spars. Each spar has a web and web attachments and has a spar length in the axial direction. The plurality of spars are connected to the panels with the web attachments located at the dense packs. The facesheets have plies oriented to cause the facesheets to carry primarily torsion and pressure loads in shear and no significant axial loads. The dense packs have plies oriented to cause the dense packs to carry all significant box bending, in axial tension and compression loads.
