【Abstract】 In this paper, formulae were developed for estimating the optimum location of horizontal strengthened stories by means of rotation compatibility analysis, in which the deformation of the strengthened stories?types of lateral load distribution?the variation of the flexural rigidity of core and axial rigidity of the perimeter columns along the height were considered, and the computer program was compiled. A 50-storey building with strengthened stories was numerically investigated and the results showed that the method is accurate enough for use in the preliminary stage of design.更多还原
