A simplified procedure for computation of the maximum amplitude of vibration of floors under foot traffic is introduced. Two types of dynamic loads are considered: the heel drop load and a modified treading in place load. Dynamic response analysis of a simplified one degree of freedom damped system is used to relate maximum amplitudes of vibration to the static response under peak loads by means of dynamic magnification factors. Response spectra of the latter are introduced. Limit lines for acceptable floor vibrations in various types of buildings are suggested for Israeli dwellings according to a literature survey and local habits. Examples of evaluation of three different reinforced concrete floor types conclude the paper.
