“…Wall-frame structures are very commonly used seismic-resistant system. Various methods of horizontal seismic response analysis have been proposed to fulfill safety anti-seismic design for the structure [1][2][3][4][5][6]. In a previous paper by the author [7], wall-frame structure under horizontal earthquakes along its orthogonal direction is simplified as a double member system and a transfer matrix method was derived to solve seismic response.…”

Based on the double member model of wall-frame structure and the corresponding transfer matrix method, the concept of frequent impedance of rigid foundation is introduced so that SSI can be taken into account. This method is more convenient and efficient compared to finite element method because of fewer structural parameters and faster calculation speed. Necessary structure parameters include 7 parameters of each storey, geometry size and total mass of foundation and elastic parameters of site soil. Totally 39 examples were calculated for 13 values of foundation mass and 3 kinds of soil, which are compared to the result of fix bottom model of upper structure. Results show that SSI does not always deduce a decrease of seismic response. Sometimes SSI may increases structural displacement evidently. The simplified method would provide structure designers an efficient tool to understand seismic behavior of wall-frame structures with various foundation and site soil.

Abstract-In order to provide a new approximated method for the preliminary design, tub-in-tube structure is simplified as a double cantilever beam system with compatible horizontal displacement at each floor along one of orthogonal direction of structure. According to the linear elastic assumption, the fluctuation equations of tubes, the equilibrium of floor and displacement compatibility conditions, the spectrum of dynamic response of structure such as displacement, rotation angle, bending moment and shear force of two tubes are expressed by a transfer vector with 6 dimensionless elements. The equations to solve seismic response, natural frequency and mode shape of structure are finally derived by taking into account the boundary condition of structure. This method has 8 parameters in each storey and is suitable for structure with different storey parameters. With the aid of Fast Fourier Transform, it can provide time history solution for displacement, rotation angle, bending moment and shear force of every tube at the top and bottom of each storey. During the preliminary design, the designer can use this method to realize a satisfied design efficiently.
