Abstract

In this paper, the rigid slab hypothesis, which is widely used in high-rise buildings, would be discussed. The modal analysis results for two building structures would be presented and compared based on the ISSS [1-4], with and without rigid slab hypothesis respectively. It could be observed from the present computing results that: (1) there are only slight difference between the natural frequencies of elastic slab model and rigid slab model; (2) while there are large difference between the effective mass coefficients for one of the buildings. So the following conclusion could be obtained that the hypothesis of rigid slab is not adaptive to all kinds of high-rise buildings and for some structures the elastic slab model also deserves attention, although its computational scale is much larger than that of rigid slab model.
