Very economical for spans starting from 6m to 13m. with imposed loads upto 10KPa (PT flat slab thickness: 225mm slab / 225mm drop. Economical span upto 35 ft). (Pt flat plate thickness: 275mm. Economical span upto 25ft)
Construction of PT flat slabs (with drop panel ) /PT flate plates is one of the quickest method available for multi storey buildings.
Increases shear strength and -ve moment capacity of slab.
simple, clean, uncluttered and widely substituted for RCC slabs, with no beams
