In tall building, it is an easy plan to transfer upper wall substructures to lower frame-wall substructures with dual rectangular-shaped slab. The dynamic responses upon transitional slabs and the effect of the slab thickness are the topics of general interest to engineers and scholars. So some theoretical, computational researches about the dynamic properties and responses of the model structures with dual rectangular-shaped slab and etc. are given through the practical project of the tall apartment building in the area of Louzi Lane (4th stage).
Keywords:  structures; transitional slabs; dynamic properties; responses; finite element
