Precast concrete suspended floor systems - selection and application

Summary

This symposium paper (678 Kb PDF) describes the site circumstances which necessitate the use of suspended construction, such as topography and soil conditions, and offers guidance on the conditions which may favour the use of precast concrete floors.

The main purpose of a floor is to support the vertical imposed loads and transmit them safely to the ground or supporting structure. In many situations the floor also has to satisfy other performance requirements such as thermal and acoustic insulation, in addition to contributing to the overall stability of the structure.

The various forms of precast concrete floor systems are discussed and how they satisfy the requirements of the Building Regulations at ground and upper floor levels including aspects such as thermal and acoustic performance. In addition, reference is made to the structural performance of the different types of precast floor system with information on a variety of construction details.
