Formslab floors

Formslab: top reinforcement:

 

• Position: normative cut for which the reinforcement is calculated.
• h-d (mm): calculated distance from the top of the concrete to the center of the reinforcement. Calculates the internal lever arm.
• hTr (mm): height of the lattice girder. This only applies to the lower reinforcement.
• Principal: Principal reinforcement
  • Basic: basic reinforcement, which runs the full length of the beam.
  • Add.: additional reinforcement, which runs over a part of the beam and can be reduced based on the moments coverage line.
• Secondary: secondary reinforcement
  • Layer: the location of the secondary reinforcement: in the 1st layer (outer) or the 2nd layer (inner).
  • Basic: secondary reinforcement which runs over the full width of the beam.
  • Add.: additional secondary reinforcement which runs over the full width of the beam.
• Prov.: if available, this can be used to define the reinforcement as already present, after which the required reinforcement is calculated.
• As;req: the required reinforcement in mm².
• As;prov: the applied reinforcement in mm².
• MEd: moment in the cut in kNm.
• MRd: moment resistance with the applied reinforcement in kNm.
• Check: the result of the norm-related checks is shown here. The checks are visible in the tooltip.
  
   
  • As: check of required and provided reinforcement.
    
    
     
  • Basic: check of basic reinforcement.
    
    
     
  • Main: check of the main reinforcement.
    
    
     
  • Cover: checking the applied cover against the required nominal cover.
    
    
     
  • Cracking: check of the crack width based on the setting under concrete options.
    
    
     
  • Fire: checking the required fire resistance with reduced cross section and steel stress.
    
    

 

Formslab: bottom reinforcement:

 

• Position: normative cut for which the reinforcement is calculated.
• h-d (mm): calculated distance from the bottom of the concrete to the center of the reinforcement. Calculates the internal lever arm.
• hTr (mm): height of the lattice girder. This only applies to the lower reinforcement.
• Principal: principalreinforcement
  • Basic: basic reinforcement, which runs the full length of the beam.
    In this example:
    The 2R8-(75+675) are the lower bars of the lattice girder
    And the R6-750 is the top bar of the lattice girder.
  • Add.: additional reinforcement, which runs over part of the beam and can be reduced based on the moments cover line.
• Secondary : secondary reinforcement
  • Layer: the location of the secondary reinforcement: in the 1st layer (outer) or the 2nd layer (inner).
  • Basic: secondary reinforcement which runs over the full width of the beam.
  • Add.: secondary reinforcement which runs over the full width of the beam.
• Prov: if available, this can be used to define the reinforcement as already present, after which the required reinforcement is calculated. A  lattice girder is fixed by default.

 

Formslab:  V-shear:

 

With the strip type "Slab" no stirrups are calculated, but a check is made on the shear force.

• Position: decisive cut where the shear force is checked.
• Side: right or left of the cut.
• Basic: the basic stirrup is shown here for reinforcement type "Strip" or "Beam". (e.g. R8-300).
• Total: the total stirrup is shown here for reinforcement type "Strip" or "Beam". (e.g. R8-150).
• Interface: here the reinforcement of the lattice girder is shown which is processed in the control of the shear between the precast concrete and poured concrete.
• As;req: the required shear reinforcement is shown here, if applicable.
• As;prov: the applied shear reinforcement is shown here, if applicable.
• VEd: acting shear force in the cut in kN.
• VRd: shear resistance based on the applied reinforcement in kN.
• Check: the result of the norm-related checks are shown here. The checks are visible in the tooltip.
   
  • As: check of required and applied reinforcement.
    
    
     
  •  Basic: check of basic reinforcement.
    
    
     
  • Main: check of the main reinforcement.
    
    
     
  • Fire: checking the required fire resistance with reduced cross section and steel stress.
