If you want to provide the column with top starter bars, the desired option must be selected from the drop-down list 1^{st }at the top of the Longitudinal dialog box:
The Top Starter Bars Longitudinal dialog box
General Settings
No starter bars: if selected, the options in this dialog are greyed-out.
Additional starter bars (main + secondary): the starter bars will be obtained extending all the longitudinal bars in the column if the starter bars concrete cover is equal to the concrete cover of the column longitudinal bars. If the concrete cover of the starter bars is different, a set of individual starter bars will be generated, having the same properties as the column longitudinal reinforcement (diameter, number, etc.).
Example:
Additional starter bars (main): the starter bars will be obtained by extending only the main longitudinal bars in the column if the starter bars concrete cover is equal to the concrete cover of the column longitudinal bars. If the concrete cover of the starter bars is different, a set of individual starter bars will be generated, having the same properties as the column main longitudinal reinforcement (diameter, number, etc.).
Example:
Extended column bars (main + secondary): the starter bars will be obtained extending all the longitudinal bars in the column dissregarding the upper starter bars concrete cover.
Example:
Extended column bars (main): the starter bars will be obtained by extending only the main longitudinal bars in the column dissregarding the upper starter bars concrete cover.
Example:
Additional starter bars according to minimum reinforcement percentage: if selected, the minimum reinforcement area recommended in EN-1992-1-1 will be used to generate the column starter bars.
Additional starter bars according to imposed required area: if selected, the option Imposed reinforcement area becomes active.
Additional starter bars according to imposed diameters: if selected, the options Main starter bars diameter and Secondary starter bars diameter become active.
Imposed reinforcement area: defines the theoretical reinforcement area of the starter bars; the value is limited to 150 cm2.
Example:
Main starter bars diameter: defines the diameter for the main reinforcement of the top starter bars.
Secondary starter bars diameter: defines the diameter for the secondary reinforcement of the top starter bars.
Example:
L-shaped starter bars: select this option if you want to create L-shaped starter bars in column-connected beams. The option requires beams adjacent to all four column edges. Available only for square or rectangular column shapes.
Example:
Bars Length
Bars length: allows deciding how to determine the length of starter bars.
Imposed bars length: define the maximum length between bars.
Seismic effects length reduction: define the reduction factor for the anchorage length, when seismic effects are considered in the design.
Non-seismic effects length reduction: define the reduction factor for the anchorage length, when seismic effects are not considered in the design.
In the case of Transversal reinforcement, you have the option to select if the upper starter bars are provided or not with links.
The Top Starter Bars Transversal dialog box
The transversal bars' position can be chosen from the following options:
- Bottom: if selected, the upper starter bars are provided with links in the bottom part (starting from the superior face of the beam towards the bottom end of the starter bars).
- Top: if selected, the upper starter bars are provided with links in the top part (starting from the superior face of the beam towards the top end of the starter bars).
- Bottom and top: if selected, the upper starter bars are provided with links on the entire length (starting from the superior face of the beam towards the top end of the starter bars and towards the bottom end also).
The transversal bars' position
Spacing: define the spacing of the transverse reinforcement for the top starter bars.
Diameter: define the diameter of the transverse reinforcement for the top starter bars.
Consider links in bar schedule: select this option to take into account the top starter bars in the drawing and the bill of quantities.
