Ribbed Slab Design Settings Section
With the Ribbed Slab Design Settings, the design parameters used in the design of concrete ribbed and waffle slabs are determined. Concrete cover, maximum and minimum reinforcement interval, etc. parameters are determined from the rib-waffle parameters window.

Concrete cover  It is the distance from the center of gravity of the tensile or compression rebar inside the rib and waffle teeth to the outer face of the concrete. |
Min. tensile percentage  It is the parameter that determines the minimum rebar to be placed in the tension zone in the rib-waffle thread. For rib and waffle threads, this parameter is used at the bottom of the tooth opening and above the tooth support. Under no circumstances can the rebar be less than the limit set by this parameter. |
Maximum percentage  It determines the upper limit of the tensile rebar (upper rebar in the support, lower rebar in the span) to be placed on the rib-waffle thread. Under no circumstances can the rebar exceed the limit specified by this parameter. If it is too much, the program will give the message "section insufficient" for the rib-waffle tooth where the maximum increase is higher. |
H for body reinforcement  If the height of the rib-waffle thread is more than the value specified in this parameter, 2 pieces of 10 body rebar are placed on the thread. |
Min. stirrup interval  In the program, the spacing of the stirrup to be placed on the rib-waffle tooth is selected not less than the value specified in this parameter. |
Max. stirrup interval  In the program, the spacing of the stirrup to be placed on the rib-waffle tooth is selected not to be more than the value specified in this parameter. |
Min. B for double stirrup  The width of the rib-waffle thread is compared with this parameter. As long as the width of the thread does not exceed the minimum width specified in this parameter, the threads are equipped with a double arm stirrup. Otherwise, they are equipped with 2 double-armed stirrups. |
Consider connecting beam rebars for stirrup lengths determination  When calculating the length of the gingiva, it is thought that it will be placed to surround the flat rebar at the bottom with the top mounting. When this option is checked, it is assumed that the flat rebars coming from the adjacent beam, if any, together with the top assembly are also included in the stirrup. As a result, the stirrup length is calculated with allowance for the rebars coming from the neighboring entrance at the top and the opening is drawn in that way. |
