Concrete formwork Design and carrier formwork scaffolding design calculation is below:​

The Concrete formwork components' modulus of elasticity and strength value is the characteristic value. For the strength value, GK = 2.0 is accepted.

...

• Secondary Beam Intervals according to primary support beam dimensions to be used in slab, beam, column, and shear wall formwork, L_ik ,

...

• Rod Intervals to be used in column, shearwall, and beam side formwork, L_b

...

N_d= Rod tensile capacity or prop axial pressure capacity

• The props sof of the beam formwork will be on each secondary support beam.

...

• The Ƥ_d value used to determine the Prop Interval, L _d, varies according to the sequential use of the scaffoldings. The total number of stories (n) where the props are used sequentially, starting from the ground story, is entered as user-defined.

• If the number of primary beam, secondary beam, rod, or prop is 2, the interval values ​​are reduced by multiplying by 0.8.

• When calculating the prop interval, the total load (nG+Q) that will affect the props is increased by 10%.

• Prop interval for slabs,
