Pile supported self-compacting fibre reinforced concrete flat slabs


New experimental evidence of structural capacity

 


Last years the use of steel fibre reinforced concrete (SFRC) increased significantly due to the acceptance of the material as a structural one in various countries throughout the world. In fact, it was an essential step forward, which motivated researchers to investigate possible application of SFRC in elements with high structural responsibility, as pile supported flat slabs for buildings (PSFSB). The implementation of this relatively new material for elements has 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 fullscale test on a four-field self-compacting fibre reinforced concrete PSFSB (5.00 by 6.00 m spans) has been performed within the context of an industrial-oriented research. The construction system has been analyzed and the prototype has been loaded in different stages with permanent and overloads in order to study both cracking and deformation responses and, eventually, led to failure. Results and outcomes of this industrial-oriented research are presented and discussed herein.
