Torsion Analysis of Core Wall Structures by Transfer Matrix Method

A theory is presented for torsion analysis of symmetrical corewall structures for tall buildings by discrete method in conjunction with transfer matrix formulation. Apart from warping deformation, the possible changes at different storeys such as the thicknesses of walls and the existence and the depths of connecting beams or slabs, are taken into account in the analysis. In an example for a particular case, the correlation of the proposed theory with results calculated from other published methods is shown. The generality and flexibility of the application of the theory is enhanced by the fact that the maximum size of matrices involved in the analysis is only 4 x 4, which is within the practical bound for design office calculations.
