Abstract:
involves the presence of a rigid soil in the design of multistory buildings. The paper investigates the effect of neglecting the soil deformability on several rigidity-related aspects of the structural analysis of multistory buildings subject to lateral forces; the rigidity of structural walls and frames; the magnitude and distribution of seismic forces; the magnitude of torsional forces; and the stresses due to temperature changes. The results show that the "fixed support analyses" lead to important distortions of the rigidities and stresses. We have either to perform analyses by taking into account the soil deformability, or to perform "fixed support analyses" in which we have to decrease the rigidities of the structural walls by multiplying them by coefficients to be determined for each type of structure.
