Abstract：
LED display support structure is divided into the floor, wall and roof type three kinds. Stress and strain characteristics of various types support structure is different. Based on finite element analysis of the three kinds of supporting structure system obtains the corresponding optimization of supporting structure, the result shows that the cantilever columns of the floor type support structure should use circular section, the horizontal support system of the wall hanging type support structure should use composite truss, the support structure of the roof type support structure should use space truss system. The supporting structure of key nodes to optimize the design, by setting the shear keys or cross stiffener structural measures such as optimizing the node stress state, to improve the safety performance of support structure.
