With the Coupling Connection Beam Design Settings, the design parameters used in the Concrete Coupling Connection Beam Design, which are modeled together with Concrete Single Footing and Strip Foundation, are determined. Concrete cover, maximum and minimum reinforcement interval, etc. parameters are determined from the coupling connection beam design settings window.

Parameters with the ( % ) sign mean the percentage expression of the rebar ratio. It is the ratio of the cross-sectional area of the reinforced concrete element to the rebar area expressed as a percentage. For example, when a “1” is written to the minimum percentage parameter, the rebar percentage is considered 1%. Since the percentage equivalent of a 0.01 rebar ratio is 1%, it is appropriate to write “1” to this parameter. |

Concrete cover  It is the distance from the center of gravity of the tension or compression rebar in the coupling connection beam to the outer face of the concrete. |
Min. tensile percentage   It is the parameter that determines the minimum rebar to be placed in the tensile zone in the coupling connection beam. 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 to be placed on the coupling connection beam. 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 is insufficient" for the coupling connection beam where the maximum strength is higher. |
Min. B for double stirrup  The coupling connection beam width is compared with this parameter. As long as the width of the coupling connection beam does not exceed the minimum width specified in this parameter, the tie beams are reinforced with a double arm stirrup. Otherwise, they are equipped with 2 double-armed stirrups. |
H for body reinforcement  If the height of the coupling connection beam is more than the value specified in this parameter, the web rebar is placed on the beam. |
Min. stirrup interval  The spacing of the stirrup to be placed on the coupling connection beam is chosen not to be less than the value specified in this parameter. |
Max. stirrup interval  The spacing of the stirrup to be placed on the coupling connection beam is chosen not to be more than the value specified in this parameter. |
Max. mounting interval  It has no function for coupling connection beam. |
