在上讲《一身二任》中,谈及高层建筑如采用框架结构,当高度增加时,单纯靠框架结构无法满足受力需要,于是考虑把楼梯间、电梯间、设备管道井等竖向构件集中起来,做一个钢筋混凝土的竖向大筒,让这个刚度和强度比柱都大的大筒承受水平荷载所产生的弯矩,而框架结构只承受垂直荷载所产生
In the above talk about “One Person and Two Men,” when it comes to high-rise buildings such as the use of a frame structure, when the height increases, simply relying on the frame structure can not meet the force requirements, then consider the vertical components such as stairwells, elevators, equipment, and other wells To get together, make a vertical large tube of reinforced concrete, and let the large tube with greater rigidity and strength than the column bear the bending moment generated by the horizontal load, while the frame structure only bears the vertical load.
