Raft Foundation Parameters

Concrete cover

It is the distance from the center of gravity of the tensile rebar inside the raft slab to the outer face of the concrete.

Min. main tensile percentage

In raft foundation working in double direction, it is the drawing pursuit in the short edge direction of the floor. In the span of the raft foundation, the rebar area is calculated from the moment found as a result of the calculation. This area is also compared to the minimum area of ​​rebar calculated using the minimum main tensile percentage. The area is used whichever is bigger.

Min. other tensile percentage

In raft foundations working in double direction, it is the pulling pursuit in the long side of the floor. In the span of the foundation, the area of ​​revar is calculated from the moment found as a result of the calculation. This area is also compared to the minimum area of ​​rebar calculated using the minimum other tensile percentage. The area is used whichever is bigger.

Min. one-way percentage

In raft foundations (L_long /L_short≥2) whose long side is 2 times more than the short side, it is the pulling pursuit in the short side direction. In the span of the foundation, the area of ​​rebar is calculated from the moment found as a result of the calculation. This area is also compared with the minimum rebar area calculated using the minimum one-way percentage. The area is used whichever is bigger.

Min. one-way other percentage

In raft foundations (L_long /L_short≥2) whose long side is 2 times more than the short side, it is the drawing pursuit in the long side direction. In the span of the foundation, the area of ​​rebar is calculated from the moment found as a result of the calculation. This area is also compared with the minimum rebar area calculated using the minimum one-way other percentage. The area is used whichever is bigger.

Min. reinforcement interval

 This parameter is taken into account when selecting the rebar in raft foundations. If the distance between two rebars is less than the minimum rebar spacing, the rebar diameter is increased.  

Max. reinforcement interval

The distance between two rebar cannot be more than the value entered in this parameter. The maximum range of rebar is used together with the x * d parameter.

Max. reinforcement interval x * d

The value entered in this parameter is multiplied by the thickness of the plate. The value found is the maximum rebar range and the distance between two rebars cannot be more than the value calculated from this parameter.

Min. reinforcement interval (Aux)

It is the parameter that limits the minimum distance between additional rebars in foundations. This parameter is taken into account when selecting additional rebar in foundations. If the distance between two additional rebars is less than the minimum rebar spacing, the rebar diameter is increased.

Max. reinforcement interval (Aux)

It is the parameter that limits the distance between two additional rebars in foundations. The distance between two additional rebar is not chosen more than the value written here. The maximum rebar spacing is compared with the parameter x * d and the smaller one is used.

Max. reinforcement interval (Aux) x * d

It is the parameter that limits the maximum distance between additional rebars in foundations. Plate thickness is diametered with the value entered in this parameter. The value found is the maximum rebar range and the distance between the two rebars is not chosen more than the value calculated from this parameter.

Minimum extra rebar length

It is the parameter that determines the minimum length of additional rebar in raft foundation.

Extra rebar length rounding factor

The length of additional reinforcement in raft foundation is the parameter that determines the rounding coefficient.

Use multiple of 5 rebar intervals

If the option is selected, the program enables the selection of rebar spacing in multiples of 5 and 5. The option is not checked, the rebar range is put as much as required for the calculation.
