Abstract:After an introduction to the approach used in the laminar analysis of coupled shear walls in structures, the limitations of this technique are outlined. It is shown that cracking may have considerable effect on the distribution of internal actions. The elasto-plastic behavior is assessed by an approximate analysis, which also yields the plastic rotations of the coupling beams. In the example of an 18 story shear core it is demonstrated with stagewise loading that the coupling system needs to possess a large ductility factor to enable the ultimate strength of the structure to be attained.
