“…A number of methods including finite element method have been developed for stability analysis of the buildings. In the literature there are numerous studies (Rutenberg et al 1988;Syngellakis & Kameshki 1994;Aristizabal-Ochoa 1997;Aristizabal-Ochoa 2002;Hoenderkamp 2002;Zalka 2002;Aristizabal-Ochoa 2003;Potzta & Kollar 2003;Zalka 2003;Girgin et al 2006;Kaveh & Salimbahrami 2006;Mageirou & Gantes 2006;Tong & Ji 2007;Gomes et al 2007;Girgin & Ozmen 2007;Xu & Wang 2007) concerning the stability analysis. Rutenberg (1988) proposed a simple approximate lower bound formula for the gravity buckling loads of coupled shear-wall structures using continuous medium assumption.…”

This study presents an approximate method based on the continuum approach and transfer matrix method for lateral stability analysis of buildings. In this method, the whole structure is idealized as an equivalent sandwich beam which includes all deformations. The effect of shear deformations of walls has been taken into consideration and incorporated in the formulation of the governing equations. Initially the stability differential equation of this equivalent sandwich beam is presented, and then shape functions for each storey is obtained by the solution of the differential equations. By using boundary conditions and stability storey transfer matrices obtained by shape functions, system buckling load can be calculated. To verify the presented method, four numerical examples have been solved. The results of the samples demonstrate the agreement between the presented method and the other methods given in the literature.

“…In research conducted by Yura [6], the bracing requirement was extended to cases where the bracing stiffness is less than the full bracing condition. Bracing requirements for frame structures were investigated by Tong and Ji [7], where a threshold bracing condition for full bracing of plane frames was derived and a critical buckling force for weakly braced frames was determined. Studies conducted by Girgin, Özmen and Orakdogen [8] showed that code formulae for determining the buckling lengths of frame columns may yield erroneous results, especially for irregular frames.…”
