Abstract

Timber floors can suffer from poor serviceability performance and require upgrade. By stiffening floors with a thin (20mm), polymer modified, fibre reinforced floor screed, excessive in-service deflections and vibrations are remediated. This paper describes the recent development of the upgrade technique through: characterisation of shear connectors under static and cyclic loading; a programme of short-term bending tests of panels; floor vibration testing and a collapse test of a complete floor. It was found that a thin topping upgrade increased the bending stiffness by up to 114%, reduced the number of modal frequencies below 40Hz from 5 to 4 and reduced the peak acceleration of the vibration response by 56.8%.
