“…Several modelling techniques are suggested for the evaluation of the elastic behavior of the lateral load resisting structures with CSWs (Syngellakis and Chan 1992, Pala and Ozmen 1995, Kinh and Tan 1999, Doran 2004. In an equivalent 1D frame model, the stiffness of a coupling beam can be defined as the product of the equivalent stiffness (combined bending and shear) of an equivalent frame and the stiffness modification factor.…”

The results of NN models, if constructed properly, generally yield a more realistic and accurate predictions. NN models are constructed based on simulating the structure and learning activities of the human brain. Garrett et al. (1997) defines a NN model as "a computational mechanism able to acquire, represent, and compute mapping from one multivariate space of information to another, given a set of data representing that mapping". This study is intended to estimate the stiffness modification factor for the coupling beam of coupled shear walls using a neural network model. In mid and high rise R/C buildings, shear wall and coupled shear wall (CSW) systems are usually

“…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.
