'General' tab
Minimum girder spacing:
Minimum offset between the girders that under no circumstances must be reduced.
Minimum girder length:
Shorter girders are omitted.
Criterion for placing girders:
Criteria for distributing girders for fitted panels:
Two at least: there are to be at least two girders even for the smallest panels.
Edge offset maintained: the edge offset is always maintained. That means for the smallest panels only one girder is used.
Round length to:
The rounding value for the girder length.
Rounding:
Do not round: no rounding.
Round exactly: 1-4 = rounded down, 5-9 = rounded up
Round down: lengths are rounded down to the above value.
Round up: lengths are rounded up to the above value.
'Height option' tab
Bar thickness / Value subtracted for calculation of girders:
This section explains how the girders are calculated in accordance with the selected option. You can define the parameters required for options 1 and 3. Here, the options are only explained; it is during design that you can select the option you want to use for calculations.
Option 1: the girder height is calculated from the wall thickness minus the concrete covers and twice the value of the bar thickness entered. The tolerances specified are taken into account.
Using this option, you can control how the height is calculated, as the girder heights specified in the girder catalog often differ from the height between the bottom boom and the top boom.
Option 2: the girder height is calculated from the wall thickness minus the concrete covers and the actual diameters of the first cross bars. If the cross bars are not in the first layer, all the diameters of the outer bars are also considered. The tolerances specified are taken into account.
Option 3: the girder height is calculated from the wall thickness minus the value specified. The program adjusts the concrete cover, so that the combination of possible spacers and calculated cross bars is as close as possible to the value specified. It is essential that the entire reinforcement is defined before it is created. Otherwise, the concrete cover cannot be calculated correctly. The tolerances specified are taken into account.
'Limits for height option' tab
Round required girder height to cm:
The required lattice girder height is calculated from the wall thickness and other parameters (depending on the selected option). The result of this calculation can be rounded:
Do not round: no rounding.
Round exactly: 1-4 = rounded down, 5-9 = rounded up
Round up: the girder height is rounded up [cm].
Round down: the girder height is rounded down [cm].
Note:
In practice this setting only has any meaning if your girder catalog has very small increments, i.e., if the wall thicknesses that can be produced differ by very little (1-2 cm). In general girders are only installed that do not exceed the calculated height.
Tolerated limits for calculating the height of girders:
Limits taken into account when lattice girders are calculated automatically using options 1 to 3. If these limits cannot be complied with, a message will be displayed and the lattice girder will not be placed. In this case, the wall element is marked in accordance with the marking option specified.
'Spacer' tab
Spacer type ... concrete cover:
[mm] Concrete covers for spacers. These values are used when the program calculates the girders automatically using option 3. The program adjusts the concrete cover so that the combination of spacers and cross bars is as near to the set value as possible.
