Layout
Column: Specify the column in which the tendon will be placed.
Section Reference Point [Center of the Section]: For the column tendons, the reference point is the center of the section.
Layout Input Method [Path Data/Tabular Data] : There is two possible ways to input tendon geometry: Tabular Data and Path Data. Both of these methods take their reference from the selected structural object, the Column's reference point. User needs to specify points on each row and these points are combined by OpenBrIM to create a tendon line.
Tabular Data: This cell is activated when Layout Input Method is selected as Tabular Data. If Layout Input Method is selected as Path Data this cell is displayed as “N/A”. The parameters of Tabular Data use the local coordinate system of the object. Refer to the figure below for the orientation of the directions.
Longitudinal Distance: This parameter can be used to specify changes in tendon locations in the transverse and vertical directions. At least two rows of definitions are required, representing the start and end points of the column tendon.
Transverse Offset: The offset value for both local and global coordinate systems, in the transverse direction for both axes, can be specified using this parameter. The generation of the object will be adjusted accordingly.
Vertical Offset: The vertical offset corresponds to the alignment's longitudinal direction and the element's vertical direction. This offset can be specified using this parameter.
Radius:
Transverse Tendon Path: If the parameter Layout Input Method is set to 'Path Data', the parameters related to the transverse tendon path can be specified. Otherwise, this option will be marked as not applicable (N/A).
