This paper is a summary of new information that has become available relating to the design of floor systems for vibration. Particular attention is given to the application of this information to precast, prestressed concrete floors. Design recommendations for three different sources of vibration are given, with the reasoning behind the recommendations. The paper will serve as a basis for revising the appropriate section of the Sixth Edition of the PC/ Design Handbook and will provide useful information to structural engineers who might be designing structures with potential vibration problems.
