Location of Column Parameters Dialog
Ribbon menu Analysis and Design tab Design Parameters title under Column Parameters by clicking the command Column Parameters can be found in the dialogue.
It determines with parameters which criteria the program will comply with in the concrete design and rebar placement stage of the elements.
It is the distance from the center of gravity of the reinforcement inside the column to the outer face of the concrete.
It is the ratio that determines the minimum value of the longitudinal rebar to be placed in the column. The multiplication of the gross area of the column with the minimum percentage parameter determines the minimum rebar area. Program means that the rebar to be placed in the column cannot be less than this area.
It is the ratio that determines the maximum value of the longitudinal rebar to be placed in the column. The multiplication of the gross area of the column by the parameter maximum percentage determines the maximum rebar area. The program compares the rebar that should be placed in the column with this area. If the area of rebar to be placed on the column is excessive, a warning of insufficient cross section is given for the column exceeding the percentage value.
Min. stirrup interval
In the program, the range of stirrups to be placed in the middle of the column is selected not less than the value specified in this parameter. The conditions given for the coiling-joining-middle zone ranges are also controlled automatically so that they are not less than the regulations.
Max. stirrup interval
In the program, the range of stirrups to be placed in the middle of the column is selected so that it is not more than the value specified in this parameter. The conditions given for the coiling-joining-middle zone ranges are also controlled automatically so that they are not less than the regulations.
If the "use as minimum" option is not checked, the program places the rebar as the pursmail value written in this line as jacket rebar on the column.
Use as minimum
If this option is not selected, the program places the rebar in the column as the pursmail value written in the "jacket percentage" line as jacket rebar. If the option is selected, the reinforced concrete calculation of the jacket is made and the rebar calculated in the jacket percentage is compared with the rebar resulting from the calculation. The amount of rebar is placed in the column as mantle rebar whichever is greater.
Column lower embracement region is 1.5lb
The column coiling zone is valid when it is made at the lower end of the column. If marked, the column wrap region is calculated as 1.5lb and the wrap region stirrups are drawn to this value. (Lb is TS500 overlap length distance.)
Use upper story element reinforcements as minimum on lower story
As a result of the analysis, if the strength of the columns in the upper story is more than the rebar of the lower story columns; It makes the rebar of the columns in the lower story equal with the columns in the upper story.
Apply high ductile transverse reinforcement design even for normal/limit ductile systems
If it is marked, the stirrup design of the columns of the normal ductile structure is made according to the highly ductile building materials.
Calculate required reinforcement using model
If marked, the required longitudinal reinforcement area in reinforced concrete columns is calculated by defining appropriate concrete and reinforcement models and section fiber in the column cross section.
Vertical rebar overlap lenght
The column allows the determination of the vertical reinforcement development length.
