Abstract

Abstract

The design and analysis of the suspension reticulated shell using green renewable wood plastic as the main material were carried out. Through tests and analysis, the related properties of various materials were compared, and the wood-plastic co-extrusion material was innovatively used as the main force rod of the reticulated shell. According to the requirements of building and wiring, the section form of wood-plastic rod was designed, and a new steel-wood-plastic combined joint was developed. The finite element analysis software was used to carry out mechanical analysis of the reticulated shell model, and the internal force, displacement and deflection of the structure with different joints were compared. Eigenvalue buckling analysis and geometric nonlinear buckling analysis considering initial defects were carried out for the reticulated shell, and the safety factor of the reticulated shell was obtained. The analysis results showed that the internal force, deformation and stability of the new reticulated shell in normal use could meet the requirements of the current relevant specifications, and it has the value of popularization and application.
