Net concrete cover

[evanes07]

[*]have a nice day; Is the concrete cover in the parameters of the program a net concrete cover? so the net concrete cover is now exactly the distance from the outermost reinforcement to the concrete finish isn't it? Is the normal concrete cover the distance from the middle of the reinforcement to the outside? Also, I would like to ask you what is the ideal concrete cover for the raft floors, I wondered your opinions?

The value entered in the Parameters dialog is the Concrete Cover value. Concrete Cover: Longitudinal reinforcement The distance between the center of gravity and the outermost concrete fiber. Net Concrete Cover: The distance between the outermost reinforcement face and the outermost concrete fiber. Net Concrete Cover values for the elements are given in TS 500 Table 9.3. Accordingly, basically 5 cm. Concrete cover can be entered as 6.5 cm to obtain a net concrete cover value of .

It was enlightening, thank you.

The value entered in the Parameters dialog is the Concrete Cover value. Concrete Cover: The distance between the longitudinal reinforcement center of gravity and the outermost concrete fiber Net Concrete Cover: The distance between the outermost reinforcement face and the outermost concrete fiber Net Concrete Cover values for the elements are given in Table 9.3 of TS 500. Accordingly, Concrete cover can be entered as 6.5 cm in order to obtain a net concrete cover value of 5 cm for the foundation. It should be 4 cm. As far as I know, 3 cm by default in ideCAD. Many companies also produce calculations/drawings according to 3 cm margins. Is this regulation not binding?

Hello Mr. Levent, According to the fire regulations, the net concrete cover of the columns must be 4 cm. As far as I know, 3 cm by default in ideCAD. Many companies also produce calculations/drawings according to 3 cm rust margin. Isn't this regulation binding?

Hello, it is written in TS500 that the concrete cover should be increased sufficiently in buildings with fire risk. The concrete cover value is not fixed in the program and the values given are minimum. These are the parametric values that the designer should change or change according to the fire risk situations.

Hakan, of course, I know that this value can be changed. I just thought, since every building is at risk of fire, shouldn't this setting be to provide 4 cm by default? As the net concrete cover increases, the minimum stirrup reinforcement ratio in the columns increases and the quantity starts to increase. That's why it's important to me.

Hakan Bey, I know of course that this value can be changed. I just thought, since every building contains a fire risk, shouldn't this setting be to provide 4 cm by default. Minimum stirrup on columns as the net concrete cover increases. The reinforcement ratio is increasing and the quantity is starting to increase. That's why it's important to me.

All parameters in the program are the values saved in the template project. If you load this template project, set the parameters to the setting you mentioned and save it to the relevant place, it will always come with that value from now on If you want the technical support team to do this, they will send you the template files as you wish.The issue you are talking about is not about software.

Minimum stirrup on columns as the net concrete cover increases. The rate of reinforcement is increasing and the quantity is starting to increase. That's why it's important to me.

Hello again, Every building carries a risk of fire, but there may be fire extinguishing systems specific to each building. The concrete cover values given are the values that predict the reinforcement to withstand fire for 120 minutes. Concrete cover values (including plaster in the building) are the values that the engineer should determine according to the fire resistance target of the calculated structure and whether there are other fire prevention systems.

Mr. Hakan, Mr. Ismail Greetings, Thank you for the details. If the fire regulations require 4 cm, I thought that it could not be done any lower, so I examined why 4 cm does not come by default in the software. Things change when protection measures and plaster are involved. In fact, the consultant in one of our projects said that 3cm was not enough, so I was confused. There are people who think that I get money from ideCAD, Mr. İsmail, I defend idecad Good work.
