Taiwan is located in seismic belt, within the scope of the Taipei basin, and three small fault, for the construction of Taipei 101, the design of the building must be to prevent the earthquake damage.Taiwan every summer will have formed the Pacific typhoon, earthquake and wind is Taipei 101 two buildings required to overcome the problem, for seismic assessment of Taipei 101, the impact of, Chen D. S. geologists began exploration site scheduled to in the vicinity of the geological structure, drilling 4 found from Taipei 101 200 meters there is a at up to 10 meters thick fault. According to these data, the National Earthquake Engineering Research Center established a different size model, to simulate the earthquake occurred, the building may occur. In order to increase the flexibility of the building to avoid the damage caused by strong earthquakes, the center of Taipei 101 is composed of a large column of 8 steel bars. However, good flexibility, but also let the building facing the breeze shock, that is, the problem of shaking. The main design is to offset the shaking generated by the wind, and the shape of the building of the wind tunnel test, through the wind tunnel test, can reduce the 30-40% wind generated by shaking.101 Taipei foundation project for a total of 15 months, up 700 thousand tons of soil, pile by 382 reinforced concrete pile structure. The center columns for dual structure, the inner tube is filled with concrete, Juzhu welding spent about two years to complete. There are at least 5 kinds of steels used in Taipei 101, according to different parts of the design, special modulation of concrete, concrete strength than the general 60%.
