1. MATERIALS SPECIFICATION
Concrete strength_28 days fck/fck,cube (Mpa)
Fluency strength rebars fyk
2. BUILDING DATA
SELECT USE FOR THE SLABS:
DL: (SUPERIMPOSSED DEAD LOAD):

LL: (LIVE LOAD- USE):

Total area of slab (m2)
Number of storeys:
Height of storey: (m)
Total height of building = PT

Total height of building = HA

3.DATA OF THE PANEL
data of the panel
Larger Length (m) = L1
Span's restraint condition L1
Shorter Length (m) = L2
Span's resgtraint condition L2
4.SELECTION OF TYPE OF SLAB

5.SECTION DESIGN POST-TENSIONING SLAB
RECOMENDED THICKNESS (Post-tensioning)=

SELECT SECTION FOR DESIGN (POST-TENSIONING SLAB)
MACIZA-SOLID SLAB

Self weight's slab:

Minimum density's tendon = kg/m2

Maximum density's tendon = kg/m2

% SELF WEIGHT TO BALANCE (between 40 to 70%)
SELECT DIAMETER OF THE STRAND
Prestressed steel required mm2/m2 to balance self weight

Number of strands per m2 or number of strands per ribs

Density of prestressed steel

Verification of minimum pre compression

Minimum rebar steel (geometrical ratio)

6.SELECTION DESIGN CONCRETE REINFORCEMENT SLAB
