About beamless raft foundation reinforcement purchase.

[ilkem]

Hello there; We are having a disagreement with a colleague whose project I am examining about the purchase of beamless raft reinforcement. (reinforcement arrangement top-bottom flat reinforcement) For the top-bottom reinforcement, it has received 1 per thousandth purchase in each direction. Minimum reinforcement purchases are separately for both upper and lower reinforcement in accordance with TS500 Article 11.4.5; I say it cannot be less than 1.5 per thousand in each direction and 3.5 per thousand in total in both directions. He says that since the upper-lower total is 2 per thousand in each direction, and the upper-lower total is 4 per thousand in both directions, it provides 1.5 and 3.5 per thousand. (The technical service of the software he used also confirmed that the selected 1/10th of the weight was correct.) When we consider the positive-negative moment in the raft foundation, the behavior of the element, the stresses on the foundation plate, etc., the minimum reinforcement determined by the specification is the minimum reinforcement that should be everywhere on the foundation plate (the missing remaining They were not convinced even though I said that additional reinforcements will be placed in the regions. Although I said that there are sample solutions with 2 per thousand as a reference in the source books, it is useless. In short, as someone who has been working with at least 1.75-2 per thousand for top-bottom reinforcement in beamless rafts for years, am I wrong or am I wrong about them? Good work everyone.

Hi; We are having a dispute with a colleague whose project I am reviewing about the purchase of beamless raft reinforcement (reinforcement arrangement top-bottom flat reinforcement) He received 1 per thousand allowances for top-bottom reinforcement in each direction. Minimum reinforcement price TS500 In accordance with Article 11.4.5, I say separately for both upper and lower reinforcement; it cannot be less than 1.5 per thousand in each direction, and a total of 3.5 per thousand in both directions. That is, the top-bottom total in each direction is 2 per thousand, and the top-bottom total in both directions. He says that it provides 1.5 and 3.5 per thousand since it is 4 per thousand. (The technical service of the software he used also confirmed that the selected 1 per thousand was correct). Even though I said that it is the minimum reinforcement that should be everywhere on the foundation plate (additional reinforcement is placed in the missing areas), they were not convinced. As a reference, they were not convinced. Although I say that there are sample solutions with 2, in vain. In short, as someone who has been working with at least 1.75-2 per thousand for top-bottom reinforcement in beamless rafts for years, am I wrong or am I wrong about them? Have a nice work everyone.
