“…The first one is the shear behaviour which represents by shear stiffnesses of columns and beams, K; the second one is the global bending of the whole structure as one unit and is represented by global bending stiffness of columns, EI g ; and the third one is the local bending of full height of individual columns using the local bending stiffness of columns, EI. This terminology provides the possibility for identifying the contributions of different bracing systems of multi-storey buildings to evaluate the local and global behaviours of those buildings in a simplified manner [8].…”

“…The reference [8] has used this terminology to deal with local and global behaviours of different bracing systems of multi-storey buildings through deriving the differential equations of these systems which depend on the continuum method with applying appropriate boundary conditions to represent the whole multi-storey building as an equivalent single column that has the sum of the relevant stiffnesses of its members. Hence, based on this, the contributions of other bracing elements such as shear walls/cores in the lateral resisting systems are assumed to be the local bending stiffness only in corresponding to the local bending stiffness of columns in rigid frame systems depending on the fact that their resistance to global bending and shear is very big.…”

-This paper assesses the reliability of applying a popular continuum method "Equivalent Column Theory" into investigating the static and dynamic performance of various tall reinforced concrete building systems. Analytical formulae of this method were used to explore many issues that relate to the local and global behaviours of tall buildings such as horizontal deflections and fundamental frequencies in x and y directions and about z-axis. Therefore, to confirm the accuracy of this method, the same models were simulated by using the commercial finite element software SAP2000 which is considered as an exact and reliable method for comparison.

SUMMARYReplacement beam formulations represent a family of 1D continuum models suitable for approximate analyses of the structural arrangements of buildings. In this paper, an energy equivalence approach is applied to coupled shear walls to develop suitable replacement beam models. Assuming properly compatible coupling fields between walls, a novel three-field coupled two-beam approach, therein providing shear and axial deformations, is proposed. The corresponding mathematical formulation provides closed-form solutions for simple loading cases with homogenous properties. Considering slender coupled shear walls, as typically found in tall buildings, the coupled two beams can be reduced to a two-field formulation, i.e., a parallel assembly of an extensible Euler-Bernoulli beam and a rotation-constraining beam. The latter model is solved analytically, and expressions for the tip displacement and base bending moment are presented. A finite element model is then presented and demonstrated to be an efficient tool for static and dynamic analyses. The effects of the axial deformation and degree of coupling on slender coupled shear wall responses are described as being dependent upon two suitable parameters. Various approximate relations are also proposed for design purposes. Finally, the validity of both analytical solutions and the finite element model is confirmed via numerical examples.
