Abstract:In the case of good design ratio of the area,we can obtain higher load of the structure about wall panel design. But for the Integrally panel, establish skin and finning separation surface position is very difficult in the practice design.Aiming at the problem on the related research work,the skin thickness in 2.5mm to 3.5 mm “hit” within the scope of whole wall, in the area under the same conditions for a given separation surface position, get the skin and the optimun design for the bar area ratio. This area ratio design of thick skin,the shape of integral panel under axial compression load capacity of the strongest.
