高层建筑钢结构有全钢结构、钢-混凝土混合结构和钢-混凝土复合结构(即SRC结构)。表5所列是这三类结构的十几个工程实例。一、全钢结构全钢结构可粗略地分为4类:1)半刚性或刚性连接平面框架结构;2)平面框架与剪力桁架共同作用结构;3)部分和中等效能筒体结构;4)高效能筒体结构。这些结构体系示于图2,图表中用楼层数表示其应用的经济限度。 1.平面框架结构:它的效能主要取决于柱网尺寸的大小和梁的高度。其优点是,
High-rise building steel structure has steel structure, steel-concrete mixed structure and steel-concrete composite structure (ie SRC structure). Table 5 lists dozens of engineering examples of these three types of structures. First, the steel structure of steel can be roughly divided into four categories: 1) semi-rigid or rigid connection plane frame structure; 2) plane frame and shear truss joint structure; 3) partial and intermediate performance cylinder structure; 4 ) High-efficiency barrel structure. These structural systems are shown in Fig. 2, where the number of floors indicates the economic limits of their application. 1. Plane frame structure: Its effectiveness depends mainly on the size of the column grid and the height of the beam. The advantage is that
