| Bearing Width | Bearing Width is the required width of bearing of the precast unit on the beam flange. |
| Slab Tolerance | Slab Tolerance is the manufacture tolerance of the precast unit. |
| Construction Tolerance | Construction Tolerance is the manufacturer and construction tolerance of the steel beam. |
The gap between planks at the supporting beam is determined based on the beam flange width, the required Bearing Width of the plank, the Slab Tolerance, and the Construction Tolerance . The beam design will be rejected if the resulting gap width is less than 30mm, and a wider beam will be selected. A gap of at least 30mm is necessary in order to fit the studs between the precast units. The gap value is also used in the determination of the effective flange width.
Information regarding the transverse reinforcement and the precast units is also displayed to indicated the values that will be used by the program. These values can not be modified by the user.
Clicking Cancel will cancel any changes made and return you to the program.
Clicking OK will cause a warning message dialog box to appear on the screen stating that proceeding with this command will clear all previously optimized beam sizes. You are given the option to continue the criteria change by clicking OK or canceling the change by clicking Cancel.
