Pile supported self-compacting fibre reinforced concrete flat slabs

Abstract

A challenging application of Steel Fibre Reinforced Concrete (SFRC) is in pile supported flat slabs. The implementation of this relatively new material for this type of structures could provide considerable advantages in comparison with traditional solutions (reinforced concrete), such as optimization of resources, reduction of execution time, reduction of environmental impact and other social aspects. However, the use of SFRC for structural purposes is limited because there are still some aspects related to both service and ultimate limit states that are not suitably covered. For this purpose, a full-scale test on a four-field self-compacting fibre reinforced concrete pile supported flat slab has been performed within the context of an industrial-oriented research. The construction system has been analysed and the prototype has been loaded in different stages with permanent and overloads in order to study both cracking and deformation responses. The results of this extensive research are presented and discussed herein.
