Slab Parameters
With the Slab Parameters command, the design parameters used in the concrete slab design are determined. Concrete cover, maximum and minimum reinforcement interval, etc. parameters are determined from the Slab Parameters window.
Location of Slab Parameters Dialog
Ribbon menu Analysis and Design tab Design Parameters title under Slab parameters by clicking on the command Slab parameters can be found in the dialogue.
Slab Parameters
It determines with parameters which criteria the program will comply with in concrete design and rebar placement stage.

Concrete cover It is the distance from the center of gravity of the tensile rebar inside the slab to the outer surface of the concrete. |
Min. main tensile percentage It is the pulling pursuit in the short edge direction of the slab in slab floors working in double direction. In the span of the slab, the area of rebar 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 tensile percentage. The area is used whichever is bigger. |
Min. other tensile percentage It is the pulling pursuit in the long side of the slab in slab floors working in double direction. In the span of the slab, the area of rebar 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 It is the pulling pursuit in the short side direction in slab floors whose long side is 2 times more than the short side. In the span of the slab, 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 It is the pulling pursuit in the long side direction in slab floors whose long side is 2 times more than the short side. In the span of the slab, 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 rebar in slab floors. 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 rebars 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 slabs. This parameter is taken into account when selecting additional rebars in slabs. 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 slabs. 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 slabs. 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 slabs. |
Extra rebar length rounding factor The length of additional reinforcement in slabs is the parameter that determines the rounding coefficient. |
Rebar shape The shape of the rebar in the slab is determined. If it will be designed as additional straight aux. rebar, if it will be designed as flat or pleated, choose the option to add piles. |
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. |
