This article reports a sub-domain method to analyze the dynamic interaction of soil-high-rise building group considering sit effect, which is the extension of the domain reduction method proposed by Bielak and his coworkers in the framework of the finite-element method, originally for building–soil–foundation interaction problems. The whole domain with high-rise building group is divided into two interrelated sub-domains, the external domain and the internal one. And the method contains two steps. In addition, the effect of the external domain to the internal domain is expressed by the equivalent forces which are put on the nodes of the interface between the two sub-domains in the second step. The formation of the equivalent force is attained according to the equation of motion. In the first step the free-field ground motion is calculated under the bedrock wave excitation, and all the nodal displacements are stored. Then the equivalent forces are calculated according the data in the first step, using the formulation of the equivalent force. In the second step a finite element analysis model of the sub-domain containing the internal domain and the high-rise building group is established, and the equivalent forces are put on the nodes of the interface. Later the seismic response of soil-high-rise building group can be calculated.

Fresh Transfer

In order to satisfy the requirement of building elevation, the setback change is carried out for the structure of a high-rise building. In order to minimize the influence of transfer story on building functions, the setback part is provided with the method of partial lapping column transfer. Lapping column transfer is a relatively fresh transfer method, which can increase the building space utilization, reduce the consumption of concrete materials, and avoid the vertical stiffness mutation of high-rise building effectively. However, the stress for lapping column transfer is rather complex, and this text makes a special analysis to the transfer story and node.

Layer Position

In order to study the conversion layer position to the effects on seismic characteristics of high-rise structure, this paper made the frame supported structure of high-rise building model using finite element software Etabs. Through four different height conversion layers of analysis model, it studies the setting height to the influence of the dynamic characteristics on the structure system. The results shows that the conversion layer position will all produce unfavorable effects on seismic performance for the whole structure, no matter that too low or too high.
