Builders design for deflection only typically by holding deflection due to live load to a maximum of l 360 where l is the floor joist span or perhaps a more restrictive l 480.
Design for floor vibration.
This article presents a straightforward overview of laboratory floor vibrations and suggests some strategies to improve the behavior of most laboratory building structures.
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.
