简介了巨型桁架结构体系的内涵、分类，并以大型支撑钢框筒为例，进行了试设计，建立了巨型桁架结构体系的分析模型，运用有限元方法进行算例分析，研究了巨型桁架筒体结构的静力特性。利用文中提出的角柱应力集中系数和材料效率指数，对框筒类结构的剪力滞后效应和轴力杆系的效率作出评价，对比分析表明采用大型支撑框筒明显改善框筒结构的剪力滞后效应，提高了结构的工作效率，巨型桁架体系是一种很有前途的超高层建筑结构体系。
The connotation and classification of mega-truss structure system are briefly introduced. Taking large-scale supported steel framed tube as an example, a trial design is carried out to establish an analytical model of mega-truss structure system. The finite element method is used to analyze the case study. Static characteristics of body structure. By using the corner column stress concentration factor and material efficiency index proposed in this paper, the shear lag effect of frame-like structure and the efficiency of axial force rod system are evaluated. The comparative analysis shows that the shear lag of frame structure can be obviously improved by using large support frame tube Effect, improve the work efficiency of the structure, giant truss system is a promising high-rise building structural system.
