世贸中心大楼的承重方式是以外围的钢柱和有电梯井的核心部分来支撑的。从基准层上看,每隔1米有一根40cm×40cm的钢柱子,形成了单边是 63米的正方形平面。建筑物分为3个部分,在44层与78层分设主电梯空中平台,在这两层可以换乘分电梯到达各个楼面。 为了抗风,世贸中心大楼的外围用钢柱和钢拱肩的组合,形成桶状的强韧的结构。这样高度的大楼在日本考虑水平力时也是从风的角度来考虑的,而不是从抗震的角度来考虑的。有报道认为大楼由于没有进行抗震设计,结构上较弱的分析并不恰当。而楼板与外
The WTC building’s load-bearing mode is supported by the outer steel columns and the core of the elevator shaft. From the reference level, every one meter there is a 40cm × 40cm steel columns, forming a square is 63 meters square. The building is divided into three parts, the main elevator in the 44 floors and 78 floors divided into air platforms, in which two floors can transfer sub-elevators to reach the various floors. In order to resist the wind, the periphery of the World Trade Center building is made of a combination of steel columns and steel spandrels to form a barrel-shaped, strong structure. Such a height of the building in Japan when considering horizontal force from the wind point of view, rather than from the seismic point of view. It has been reported that the structurally weaker analysis is not appropriate because of the lack of seismic design of the building. The floor and outside
