摘要

摘要: 对采用绿色可再生木塑作为主要材料的悬挂网壳进行了设计和分析。对比了多种材料的相关性能，创新性地采用木塑共挤材料作为网壳的主要受力杆件；结合建筑和布线的需求，设计了木塑杆件的截面形式，开发了新型钢–木塑组合节点；采用有限元分析软件对网壳模型进行了相关的力学分析，对比了不同节点连接形式的结构内力、位移及挠度；对网壳进行了特征值屈曲分析及考虑初始缺陷的几何非线性屈曲分析，得到了该网壳的安全系数。分析结果表明，该新型网壳在正常使用过程中的结构内力、变形和稳定性均能满足现行相关规范要求，具备推广应用价值。

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.
