Hilti HSA Anchors

1. The document provides structural calculations for an end connection using Hilti bolts. 2. Tensile and shear resistances are calculated based on steel resistance, concrete pull-out resistance, concrete cone resistance, and concrete splitting resistance. 3. For a M16 HSA-R bolt with a 400mm concrete slab, the tensile resistance is 18.86kN and the shear resistance is 45.2kN. Calculations are also provided for a M16 HSA-F bolt.

f3,N = 0.5*(1+s/scr,N) = 0.69
fre,N = 0.5 +hef/200 = 0.90

- Concrete Splitting Resistance (NRd,sp) =


NRd,sp = N0Rd,c*fB*f1,sp*f2,sp*f3,sp*fh,sp*fre,N 28.68 kN
Where: N0Rd,c = 24.10 kN
fB = 1.26

c/ccr,N = 4.17
s/scr,N = 0.38
f1,sp= 0.7+0.3* c/ccr,N = 1.00
f2,sp = 0.5*(1+c/ccr,N) = 1.00
f3,sp = 0.5*(1+s/scr,N) = 0.69

fhef = 0.05*(hef/d)^1.68 = 0.75
fc = (d/c)^0.19 = 0.52

So, Shear resistance is : 45.20 kN
