在高层和超高层钢筋混凝土建筑中,下部柱的内力很大,其轴力可以达到3000～4000kN甚至更高.在这种情况下,为减小柱子的截面,应视轴力的大小分别采用高强混凝土、约束混凝土、钢管混凝土和型钢混凝土或其复合柱.文中介绍了这些柱型的性能及在国内外的使用经验和轴压比限值,并给出了如何根据轴力大小进行选型的算例. In high-rise and super high-rise buildings, the internal forces of the lower columns are very large, and their axial forces can reach 3000 to 4000 kN or even higher. In this case, in order to reduce the cross section of the columns, the axial forces should be respectively High-strength concrete, confined concrete, concrete-filled steel tube and steel reinforced concrete or their composite columns.This paper introduces the performance of these columns and their experience at home and abroad and axial compression ratio limits, and gives how to select according to the size of the axial force Example.
