The design shear resistance of a connection is calculated according to EN 1993-1-8 Art 6.2.2.
As it is described in EN 1993-1-8 Art 6.2.2 (2), the contribution of each bolt is dependent on the fact, whether the bolt should resist the tension or not. Each bolt contributes with:
The design shear force resistance of a joint Vz,Rd is then calculated as:
with:
| Fv,Rd | design shear resistance of a bolt calculated according to EN 1993-1-8 Art 3.6.1 Table 3.4 |
| nt | number of bolts which are also required to resist tension |
| nn | number of bolts which are not required to resist tension |
The design bearing resistance of a joint Fb,Rd of a bolt is calculated according to EN 1993-1-8 Art 3.6.1 Table 3.4 separately for each relevant component:
with:
| ntot | total number of bolts |
The final design shear force resistance of a joint Vz,Rd is taken as minimum of design shear force resistance and the design bearing resistance of a joint.
For further info on calculation of shear force resistance of a normal bolt see chapter: "Normal bolts".
For further info on the calculation of shear force resistance for connection with 4 bolts per row see the chapter: "Bolt-rows with 4 bolts".
