Stair Parameters
With the Stair Parameters command, the design parameters used in the Concrete Stair Design are determined. Concrete cover, maximum and minimum reinforcement interval, minimum tension percentage for main and other direction, etc. parameters are determined from the stair parameters window.
Location of Stair Parameters Dialog
It is in the Concrete icon list in the Design Parameters section of the Analysis and Design menu in the ribbon menu.
Stair 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 rebar to the outer face of the concrete. |
Min. main tensile percentage It is the pull pursuit in the short edge direction of the plate in the plates working in double direction. |
Min. other tensile percentage It is the pulling pursuit in the direction of the long side of the plate in plates working in double direction. |
Min. one-way percentage It is the pulling pursuit in the short side direction in the plates with the long side 2 times more than the short side (L_{long}/L_{short }≥2). |
Min. one-way other percentage It is the pulling pursuit in the long side direction in the plates with the long side 2 times more than the short side (L_{long}/L_{short }≥2). |
Min. reinforcement interval This parameter is taken into account when selecting the rebar. 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 default value for this parameter is 1.5. 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. This parameter is taken into account when selecting additional rebar. 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 additional rebar. The distance between two additional rebaris 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. 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. |
