Global Reaction Summations .5g + deadweight Static Analysis Response Spectra Modal Analysis Global Reaction Summations
Hilti Drop-In Hilti HDI Concrete Flush Anchor Tests Allowable Design Loads are ¼ these Values, i.e. a F.S. of 4 is recommended A shear design capacity of 13000 lbs and a tensile capacity of 9000lbs is recommended. These envelope static and modal analyses. For shear, use 13000/6224*4 = 8 ½ “ Hiltis, For Tension use 9000/6751*4=5 ½ “Hilties 13 ½ “ Hiltis Total per Leg -or For shear use 13000/9696*4 = 4 5/8 Hiltis, for Tension use 4 5/8 Hiltis Or 8 5/8 Hilti’s Total per Leg
I Beam Support Column Static Analysis Results ¾ Hilti Test Capacity – Use ¼ Value This I Beam is Almost Completely in Compression This I Beam is Mostly in Tension – The Net Load is 35833 N or 8000 lbs – Small for ¾ inch bolts and Hiltis
From DOE Regs Static Acceleration used in the original NSTX qualification Fp = Z I Cp WP = 0.135 Wp This analysis used .5g – For Extra Weight and Uncertainty This is 1e6*.2248/4 = 56200 lbs per Hilti Consider adding shear plates with many Hiltis on outboard Diagonal Braces
