Design For Floor Vibration

Because of the complexities involved in human response to vibration and the different.

Design for floor vibration.

This design guide is organized for the reader to move from basic principles of floor vibration and the associated termi nology in chapter 1 to serviceability criteria for evaluation and design in chapter 2 to estimation of natural floor fre quency the most important floor vibration property in chap. Testing and vibration performance assessment based on experimental data are powerful tools which can be used to ascertain the as built vibration behaviour of building floors. Preventing or reducing floor vibration problems. This article presents a straightforward overview of laboratory floor vibrations and suggests some strategies to improve the behavior of most laboratory building structures.

A new approach developed by the uk s steel construction institute sci uses a finite element approach to determine the accelerations at various points on the floor due to walking activity. These accelerations are then compared with the limits cited in the international standard iso 10137 to determine if the. For slender floor structures as made in steel or composite construction serviceability criteria govern the design. Annoying vibrations due to normal walking activity have been observed more.

Dynamic testing of floors. Codes don t regulate floor vibration. Sophisticated finite element analysis fea techniques can be used to solve floor vibration problems which can affect people in a high rise office boardroom or disturb sensitive medical and industrial equipment and to design isolation systems for both small equipment and entire buildings. This publication provides guidance for vibration design of all steel framed floor and building types.

It deals with the human perception of vibration and the criteria by which it is measured. The purpose of this publication is to provide design engineers with a practical yet comprehensive review of the criteria and methods available to prevent floor vibration problems. The concepts of floor response and the different types of excitation produced by occupant induced vibrations are explained. Guidance is given for.

Design of floor for vibration. Serviceability rather than strength is the most critical design requirement for vibration vulnerable floor constructions. In canada the building code includes limits on floor vibration. With thoughtful design the engineer can create a floor system that properly damps vibrations for sensitive equipment in an affordable and functionally flexible structure.
