DESIGN PRECAST PRESTRESSED HOLLOW CORE SLABS


Project Title
   




Design Code,     Fire rating,   min     Select HC,    

Diameter of Strands;
Strand 1,   mm     nos,   ,     Strand 2,   mm     nos,   ,    
Strand 3,   mm     nos,       Strand 4,   mm     nos,      

Concrete strength ;
fck,cube,transfer   N/mm2     fck,cube,topping   N/mm2     fck,cube,service   N/mm2    

fpst =   N/mm2    

Max initial prestress = fpst_initial =   % of fpst     % loss =   %    

Lifting for Demoulding Stage
lifting location ,   m from each ends of the HC slab    

Reinforcement for topping concrete
fst,   N/mm2     BRC,   N/mm2    

φrebars ,   mm     rebarspacing ,   mm c/c     φmesh ,   mm     meshspacing ,   mm c/c    
Note: Cover to rebars for topping taken as 30mm from top.    

Hollow Core Span, Ls = m    

Nos of equal span props during topping stage, Nprops =   nos     (unavailable)
note
refers to Props AT EQUAL SPACINGS other that those at the supporting beams location    

topping, htopping =   mm    

Live Loads, LL =   kN/m2     Constructio Live Loads, LLtopping =   kN/m2     sdL=   kN/m2    

Bearing length, Lb   mm
