Abstract:Seismic design of the bottom of high-rise buildings is very important. In order to improve seismic performance of the bottom structures and avoid the overall collapse of high-rise buildings caused by serious damage of the bottom structures under rare earthquake, effective measures should be taken. Several problems of the bottom of high-rise buildings, such as constrained part and stilted building were discussed. Some practical measures for seismic design of the bottom of high-rise buildings were provided.

Keywords:high-rise building； seismic design； constrained part； stilted building
