    AS 3600 Cl 10.8 Transmission of Axial Force through floor systems

    Hi BentEng, Thank you for your reply. What you are saying makes sense that we can’t have two sides fixity 0.7 just from the slab. However, I looked at commentary and it says that that figure is just an approximation where fixed ends are allowed a bit of rotation. That is why I used the...

    AS 3600 Cl 10.8 Transmission of Axial Force through floor systems

    aah yep that makes sense. I have done some calcs and tried to make it work without taking any rotation into the pad. I was able to get gamma as 0.15 for slab and if I consider gamma for pad footing as 10 which means no rotation, I am still getting k=0.725 if my calcs are correct. My slab above...

    AS 3600 Cl 10.8 Transmission of Axial Force through floor systems

    Thank you for that guys. Makes sense. The issue is for some of these columns, I have got the above column at 90 degrees, which means I cannot get all the bars through from the bars under. I am thinking about putting a 750mm deep drop panel so that I can develop my 12N32 bars in compression...

    AS 3600 Cl 10.8 Transmission of Axial Force through floor systems

    Hi guys, I am designing some 65MPa columns above and below a 40MPa slab. Referring to the Cl 10.8, it is a bit confusing to understand. Since I have to comply with (b) part of this clause, I have calculated my f'ce = 55MPa. It is a bit unclear whether this is the maximum compressive strength...
