现代高层建筑中,悬挂式建筑特别令人感兴趣。以英国伦敦落成的两座20层悬挂式大厦为例(图1),整座大厦只是一个12米见方的钢筋混凝土井筒结构或称方塔。电梯、楼梯、管道、电缆均敷设在塔内或塔壁上。整座大厦的竖向荷载、侧向风载和地震力等均由这根空心巨柱承载。方塔顶部设置一 Suspended buildings are of particular interest in modern high-rise buildings.

Elevator, stairs, pipes, cables are laid in the tower or tower wall. The vertical load, lateral wind load and seismic force of the whole building are all carried by this hollow pillar.
