Guidance Note Shear connectors No. 2 - Steel Construction

Note that in steel box girders with composite flanges, there will be a concentration of shear transference local to the box webs. Shear studs will need to be arranged to suit this, resulting in a higher density of connectors above the webs - see EN 1994-2 Clause 9.4. Size of shear connectors Clearly, the design for shear transfer will have
