Detailing of bolts and welds according to Chinese standard
Bolts
The minimum allowable distance of bolts is checked according to Table 11.5.2.
Minimum allowable distance of bolts; d0 – bolt hole diameter
| Minimum allowable distance | |
| Bolt pitch | \( 3 \cdot d_0 \) |
| End distance parallel to load | \( 2 \cdot d_0 \) |
| Edge distance perpendicular to load (bearing bolt type) | \( 1.2 \cdot d_0 \) |
| Edge distance perpendicular to load (preloded bolt type) | \( 1.5 \cdot d_0 \) |
Welds
The minimal weld size hf is checked according to Table 11.3.5. The weld size is determined from weld throat thickness: \( h_f = \sqrt{2} \cdot h_e \).
Minimal weld size hf
| Thickness of plate [mm] | Minimum weld size [mm] |
| \( t \le 6 \) | 3 |
| \( 6 < t \le 12 \) | 5 |
| \( 12 < t \le 20 \) | 6 |
| \( 20<t \) | 8 |
