Influence of soft land seismic dynamic characteristics on high-rise building in Tianjin

With a high speed development of the economy in Tianjin,plenty of high-rise buildings appear promptly.The large scope of soft soil in Tianjin has the worst anti-seismic characteristics, and the high-rise building on the soft site is apt to suffer the damage of earthquake.The influence of the soft land seismic dynamic characteristics on the high-rise buildings in Tianjin is discussed emphatically in the light of an analysis of the seismic reaction for an engineering site in a central area in Tianjin. And some problems that should be discussed further are put forward.
