Slab on pile

Pile supported slabs are quite common in  areas where soil-structure interaction may create differential settlement or long term tolerance problems.  .

The structural slab is designed without any ground support.

As the fiber content increases, propagation of newly formed cracks requires a much higher level of energy than what was used to create them. Under these circumstances, more new cracks are formed, whereas the existing cracks which require additional energy to propagate behave as stationary and remain inactive. This results in multiple crack formation as opposed to the propagation of a dominant single crack. Under this situation, the cracking diffuses and distributes within a band of high tensile stress regions in the elevated slab. 

Support heavy duty load

Suspended ground slabs are generally subjected to  high  concentrated  point  loading  (150  kN)  intensities  as  well  as  uniformly  distributed loadings (50 kN/m²) and wheel loads.

The success is evident as SFRC slabs resist high moment intensities as well as high shear and punching shear stresses. Shrinkage cracking control is directly obtained by the use of fiber reinforcement. Large bay areas are possible due to shrinkage control and directly result in a reduced number of construction joints.
