Evaluation of a proposed vibration criterion

Abstract

A lightweight floor system consisting of a concrete slab on steel joists or beams is susceptible to annoying vibrations caused by walking. This investigation considers a criterion developed by Allen (1991) that indicates whether a proposed structural floor system is acceptable for walking vibrations.

The proposed vibration criterion is evaluated using the Murray vibration criterion as a basis for comparison. Both criteria are used to determine the acceptability of existing office floors, shopping malls, and pedestrian bridges. The evaluation results for each criteria are compared and the strengths and weaknesses of both criteria are discussed in detail.

A derivation is presented for the proposed criterion and the calculations involved in utilizing the criterion are described. Finally, recommendations for future research are discussed based on the evaluation results of the investigation.
