Supplementary reinforcement to cast-in anchors within a RC beam

[Mohrtec]

Hello all,

I'm looking for clarification on whether or not I need supplementary reinforcement within a 900x1000mm beam to which a 30mm cast-in shear plate with 30 welded anchor studs (5 rows of 6) is fixed. The studs are 30mm in diameter. There is a shear force of 1400kN acting on the shear plate. Thus far I've completed checks on the anchor, concrete cone pull-out, concrete splitting, blowout (although not necessary as no tension), pry-out and concrete edge, all of which are acceptable.

Given that this is a large force will supplementary reinforcement still be necessary?

Some questions ;

- Is the applicable code BS-EN 1992-4 ?

- Is the shear force of 1400kN acting on transversal direction?

- What about the other loads acting on 900x1000mm beam ?

- Can you provide some sketches ?

Just by rule of thumb, the shear resistance of RC beam could be less than 1400kN and you need at least provide some shear reinf.




My opinion..





I cannot give you the formula for success, but I can give you the formula for failure..It is: Try to please everybody.
