摘　　要：为了拓展筒体结构在高层建筑中的应用,根据结构同时承受竖向力和侧向力的受力特点,提出了一种高层筒体结构新体系——高层网筒结构,该结构体系是各种形式的竖向网格结构围合而成的空间网格状筒体结构。该文构思了该结构体系的基本组成和网格形式,给出了可以在实际工程中应用的几种空间几何形式,造型多样、美观,可适应复杂的建筑造型。并通过实例计算,简要分析了网筒结构的受力特点,初步揭示了网筒结构的优势:空间工作,传力简捷;重量轻,整体刚度大。In order to extend the application of tube structures, a new tube structure, i.e. , a grid tube structure, was developed as the exterior structure for tall buildings subjected to simultaneous vertical and lateral loads. The structure is a reticulated structure assembled as a surrounding mesh. The structural [raining is composed of the main and subordinate components, such as diagrid columns and ring beams. Various geometric tube shapes can be used to form unusual configurations. Analysis of a design example shows how to calculate the larger overall stiffness of the grid tube structure and the advantages of the grid tube structure.
