Is it correct that the gap between rebar in piles should be 100mm for bar diameters greater than 32mm.and its aggregate size plus 5mm or bar diameter?.
@jayrod12, I have set up a meet with Hilti to discuss my concerns. It appears that the general consensus is that the Hilti method is reliable provided the inputs are correct. Thats the re assurance I needed. I have also specified a pullout test load on of 3% of the total number just in case...
Just done a calc of foundation anchor bolts using hilti online software. The hilti bolt capacities (based on combined cone pull out) appear much higher than the Ec code capacity (based on bond stress between anchor an concrete). Is the hilti software reliable?. Been looking at previous...
Thank you so much for the tips.
Hokie66, the reason for cranking the bars has been requested by the contractor. The original cage had full length bars but the contractor prefers to do the cage in segments using casings a relatively smaller crane for lifting the prefabricated cage. Cranking the...
How do I calculate outward busting forces in a circular concrete pile at positions of cracked longitudinal rebars. This column is 800mm dia with 15No dia 32mm bars to enable splicing. The pile is 23m long. The rebar has 2 spices. Links are a spiral dia 16mm bars at 250mm pitch. Because there are...
