Analysis of building structures by replacement sandwich beams

In this paper replacement beams of building structures are developed, and the stiffnesses of the replacement beams are derived. The analysis is robust and can be used for slender and wide structures consisting of frames, trusses, shear walls, or coupled shear walls. The utility of the derived replacement beam is demonstrated through the examples of the in plane and flexural–torsional buckling and vibration analyses of high-rise buildings.
