I am completing a check on a baseplate fixing with uplift and a shear load. The baseplate is close to a return corener of the concrete base material when reviewed on plan. When using hilti profis anchor it is not possible to create a base material with the same kind of profile and the use of a straight edge seems overly conservative when assessing edge breakout.
What would be the procedure for checking a baseplate with this kind of proximity to an edge, is it possible to review that the shear loading transfers into the concrete base and therefore an edge distance is not required?
I have included a sketch to outline the location of the baseplate on plan.
Many thanks,
Sam
Thanks for your question and sketch. Ok it's not possible to model a reentrant corner and the way I would suggest to check the connection is to model a bottom edge. Please see a modified sketch with the yellow line being extended across the bottom of the plate. You'll also notice where I've actually shown a slightly larger area of concrete to resist the shear. Now assuming the shear is running right to left or left to right the shear would be distributed amongst the 4 anchors. Depending upon the required load, slab details then the edge distance to the left then by eye would potentially be the governing factor or pryout failure.
