摘　　要：针对历年大学生结构设计竞赛中空间杆系结构的赛题,以复压竹皮和竹杆为原材料设计空间杆系结构并进行其结构形式分析。利用有限元软件MIDAS Gen建模和计算,对系列空间杆系结构在多种荷载工况下的应力和位移进行数值模拟仿真,分析其承载能力和变形特征,总结出空间杆系结构在荷载组合工况下的强度、变形等力学特性以及结构优化的有效措施。In response to the spatial bar structure problems posed in previous national structural design contest for college students,this study focuses on designing spatial bar structures using bamboo veneer and bamboo rods as raw materials and conducting structural type analysis.Utilizing the finite element software MIDAS Gen for modeling and calculations,numerical simulations of stress and displacement are conducted for a series of spatial bar structures under various load conditions.This analysis aims to evaluate their load-bearing capacities and deformation characteristics,and to summarize the mechanical properties such as strength and deformation of spatial bar structures under combined load conditions,as well as effective measures for structural optimization.
