Properties for calculating bolt spacings:
Space (mm): | |
Coefficient of edge distance (e1,e2): | |
Coefficient of pitch distance (p1,p2): |
Explanations:
1. Space is space between washer under the bolt head and the end of profile or tehe beginning of the radius.
2. Coefficient of edge/pitch distance:
These coefficients can be freely set. The preset values are minimum values according to EN 1993-1-8:12/2006 (tab.3.3).
But can be used recommended values, e.g. accordin to Prof. Josef Macháček (Faculty of Civil Engineering CTU in Prague) : e1 = 2,5 * d0, e2 = 2,0 * d0, p1,p2 = 3,5 * d0
3. Bolt pitches are calculated for M10 - M24 bolts only.
