Access this option by selecting the Reinforcement lap tab in the Reinforcement: definition and detailing dialog. The following dialog displays:
When main reinforcement is being distributed, it may prove necessary to use reinforcement laps. If reinforcement length exceeds the value defined in the preferences (e.g. 12 000 mm), then the options provided on this tab enable defining reinforcement laps (connections of reinforcing bars).
The options provided on this tab allow you to:
- Determine if bars should be with or without laps
- Specify parameters of bars with laps.
If the Bars without lap splices option is selected, then reinforcement laps will not be used in a reinforcement distribution. Bars will be distributed so that they fit the distribution region, but without considering the maximum length of bars (single bars in the distribution may be longer than Lmax) and without laps. The reinforcement table included information about the total length of bars in a distribution multiplied by a factor defined in the Job preferences dialog (the Options tab).
'LM' bars are bars presented in the table in running meters as a total sum of all segments formed as a result of distribution.
If the Bars with lap splices option is selected, then reinforcement laps is created during reinforcement distribution. The following parameters of reinforcement laps are defined:
- A lap length (proposed value is a multiple of reinforcement diameter)
- A value of an offset when laps are arranged in the passing manner.
Definition of positions of Z laps involve changing the lap position (mirror reflection with respect to the bar center).
