Secondly, based on the finite element method (FEM) by ANSYS of the original model and the whole-reinforced model by carbon fiber reinforced plastic (CFRP), we definitely know the difference of the static and stability performance between the two models. The evaluation of the CFRP reinforcement ofthe spatial netlike shell is obtained by studying on the results ofthe analysis.
