holding down bolts - shear design

[ByrnePM]

I am wondering if ROBOT checks the bearing capacity of the concrete in a baseplate design for bolts subject to shear (to Eurocode standard) ...I cant seem to see it in the result output nor can I see an option for the check when defining the connection? 

I feel that If this check is neglected than connection design may be unsafe as this criteria can often be critical when designing bolts for shear (if not using nib)

Thanks,

Robot performes a number of checks (see below) for shear verification and it is the weakest component that governs the design.

F1,vb,Rd,z =	360.00	[kN]	Resistance of an anchor bolt for bearing pressure onto the base plate		[6.2.2.(7)]
F2,vb,Rd =	37.00	[kN]	Shear resistance of a bolt - without lever arm		[6.2.2.(7)]
Ff,Rd =	0.00	[kN]	Slip resistance		[6.2.2.(6)]
Fv,Rd,wg,z =	102.67	[kN]	Resistance for bearing pressure of the wedge onto concrete
The final resistance is calculated as: Vj,Rd,z = nb*min(F1,vb,Rd,z, F2,vb,Rd) + Fv,Rd,wg,z + Ff,Rd When CEB cionditions are switched on in addition the following verifications are done:  Fv,Rd,sm = 0.01 [kN] Shear resistance of a bolt - with lever arm CEB [9.3.1]   Fv,Rd,cp = 155.03 [kN] Concrete resistance for pry-out failure CEB [9.3.1] Fv,Rd,c,z = 255.39 [kN] Concrete resistance for edge failure CEB [9.3.1]                   and the final resistance is determine as: Vj,Rd,z = nb*min(F1,vb,Rd,z, F2,vb,Rd, Fv,Rd,sm, Fv,Rd,cp, Fv,Rd,c,z) + Fv,Rd,wg,z + Ff,Rd The ratio is calculated by comapring the acting force with teh above resistance Vj,Ed,z / Vj,Rd,z ≤ 1,0 Assuming that you mean F2,vb,Rd resistance then it is checked according to paragraph 6.2.2.(7) of the code.
