In the United States, 24.6 m or 7 layer above as high-rise buildings; In Japan, 31m or 8 layer and above as high-rise buildings; In Britain, to have equal to or greater than 24.3 m architecture as high-rise buildings. Since 2005 provisions in China more than 10 layers of residential buildings and more than 24 meters tall other civil building for high-rise buildings. KEYWARD：High-Rise Buildings；Shear-Wall Systems；Rigid-Frame Systems 1. High-rise building profiles Although the basic principles of vertical and horizontal subsystem design remain the same for low- , medium- , or high-rise buildings, when a building gets high the vertical subsystems become a controlling problem for two reasons. Higher vertical loads will require larger columns, walls, and shafts. But, more significantly, the overturning moment and the shear deflections produced by lateral forces are much larger and must be carefully provided for. The vertical subsystems in a high-rise building transmit accumulated gravity load from story to story, thus requiring larger column or wall sections to support such loading. In addition these same vertical subsystems must transmit lateral loads, such as wind or seismic loads, to the foundations. However, in contrast to vertical load, lateral load effects on buildings are not linear and increase rapidly with increase in height. For example under wind load , the overturning moment at the base of buildings varies approximately as the square of a buildings may vary as the fourth power of buildings height , other things being equal. Earthquake produces an even more pronounced effect. When the structure f
