The gap is calculated as follows:
| gap = Flange Width – 2×(Bearing Width) – Slab Tolerance – Construction Tolerance | |
where
| Flange Width | = | the width of the top flange of the beam |
| Bearing Width and Slab Tolerance | = | values specified in
|
| Construction Tolerance | = | the greater of the value specified in
and Span/1000 |
The minimum allowable gap is 30mm. If the calculated gap is less than that value the beam size is rejected and a beam with a wider flange width is selected.
Note: The minimum allowable flange width is 165mm. If the top flange is less than that the beam size is rejected and a beam with a wider flange width is selected.
