Abstract

The paper addresses uncertainty related to boundary conditions of a rectangular concrete floor with focus on its impact on the modal properties of the flooring system. For this purpose, finite-element analysis has been performed using Mindlin theory The hypothesis is that even though a floor is intended to be simply supported along a given edge, if may to some extent be fixed, and vice versa. The influence of variation in the support conditions on the variation of eigenfrequencies of the flooring system is discussed, and the consequences for design of flooring systems is addressed.
