Design And Analysis For Seismic Behavior Of Connected Multi-tower Structures With An Enlarged Base

Multi-tower structure is a kind of complicated structural system. Because of couplingvibration of the towers, the seismic design method of mufti-tower building is quite different from the one of usual structural system. Some requests about the seismic design of multi-tower structure which is a kind of complicated tall buildings, are regulated in "Technical specification for concrete structures of tall building"(JGJ3-2002), but the regulations about the seismic analysis and the constructional measures are not definite and thorough enough to operate. In practice, the number of tower is not more than two, three or more towers are so less designed that less practical experiences are available. Therefore, it is necessary to analysis the properties of seismic response of complicated tall building with two or more towers.In this paper, two -tower building with name of the NO.12th building of South centry park is analyzed by the international current program SATWE , considering seismic...
