Thanks You
I am using formulas for elongation and evrithing is OK for long bad (400ft), but for short bad (50) I am getting the forces above the 80% of the specified minimum ultimeate tensile strength.
Any idea what is wrong.
Thanks
I have 400ft long bed of hollowcore. On the begining of the bed there is no good copaction of the concrete so how I could know how far from the end of the bed cut the first slab to avoid slippage.
Thanks
