Similar structure and mechanics behavior exist between the bamboo stem and the crane’s box girder. We studied the relation between the structure parameters and mechanics behavior for the bamboo structure and, it showed that the distance of stems increases by the decreasing of the bending moment and the shear force in the bamboo stem. Meanwhile, the permitted maximum distance between two adjacent stiffeners is established by considering the effects of the distance between two adjacent stiffeners on the rigidity and strength design indexes of the box girder. The strategy of the bionic optimization is to allow variable distances between two adjacent stiffeners so that the box girder has uniformly distributed buckling stability. The optimization is carried out by the finite element nonlinear buckling analysis. On the other hand, through case studies we find that the bionic box girder requires smaller number of stiffeners and smaller amount of steel than the traditional box girder. Moreover, the bionic box girder possesses more uniform buckling stability along the direction of its axis.
