Numerical Elastic Analysis of Coupled Shear Walls.

Assessment of the Lateral Stiffness of Walls With Openings

“…Coull and Choudhury [1,2] proposed a simple method to estimate the peak lateral displacement of walls coupled by slabs or beams (Figure 3), where the lateral loads are resisted entirely by the walls. They proposed a simplified model where the coupling slabs or beams are replaced by an equivalent continuum shear media; that is, the coupling beams with individual stiffnesses EI p are replaced by an equivalent continuum which stiffness per unit height (h) is EI p /h.…”

“…In fact, many expressions, approximations and simplified analysis methods date back to those dates, because during that decade several midrise buildings with shear walls were built, which fostered practical research studies. Among other methods proposed at the times, one can highlight for their simplicity the methods proposed by Coull and Choudhury [1,2] and the Equivalent Frame Method (EFM) proposed by Schwaighofer and Microys [3]. The approximations obtained with these methods were calibrated then with the results of few low rise walls with symmetrical openings patterns with respect to a vertical axis.…”

Analysis of shear wall structures of variable cross section

“…In order to test the correctness of the presented technique, the obtained results have been compared with those obtained from tests on araldite model, given by Coull et al (1973). The dimensions of analysed 21‐storey model are shown in Figure 3.…”

“…The dimensions of analysed 21‐storey model are shown in Figure 3. All dimensions are given in inches, according to (Coull et al , 1973). The thickness of walls equals 0.625 in.…”

“…The application of the continuum method to the analysis of plane coupled shear walls with stepwise changes in the cross section has been considered by Coull and Puri (1967, 1968), Traum (1967), Pisanty and Traum (1970), Rosman (1971a) and Aksogan et al (2003), using the analytical method of solving differential equations. Methods proposed by Coull et al (1973) and Tso and Chan (1973) are based on a transfer matrix technique. Some authors (Lis, 1977; Cheung et al , 1998) applied the finite strip method to the analysis of coupled shear walls of variable cross section.…”
