Hello, No change is required. The parameters that change according to the concrete class are calculated automatically by the program.

Check the Superstructure interactive solution option. *There is an error in the continuous foundation column-panel connections in the project. For example, it seems that the CF12 Foundation is not connected to the S7 column, the TK14-15 foundations are not connected to the S8 column. The continuous foundations entered under the panel object must also be entered from one node to the other node of the panel. *S08 Both ends of the rib beams are empty in the ribbed slab no. No. A rib cannot be defined in this way. It would be appropriate to enter a beam on the upper and lower edges of the slab. *The loads on the rib slab seem a bit excessive to me. (If the weight of the rib beams is also included in the load, this no need to include the load.The program automatically takes into account the load formed by the rib beams.And this information is slab reinforced concrete me report.) The attached document union.pdf can be a guide for solving the problem B in columns."physician":gssy4a3g" said:I'm bothered, but no matter what I did, I couldn't solve the junction area problem, where did I make a mistake, I would appreciate your help, thank you
Hello. I am writing here because I made a mistake on this subject. 'minimum value' is written as 0.001 by default and it does not change automatically according to the concrete class. Wouldn't it be appropriate to calculate and change this value automatically as '0.8xfctd/fyd' according to TS500? Regards..."Levent Özpak":25i3weri" said:Hi, No change is required.

The program calculates and uses this value according to the concrete class already entered."proisa":ttkul12j" said:Hello. I'm writing here because I made a mistake on this subject.

The value in the beam parameters does not change. It is also a minimum parameter you enter. The program looks at the value you entered and the value it calculated from the material class in TS500. Whichever is negative, it uses the minimum value. You If you want the value in TS500 to be used all the time, enter a small value in the beam parameters. Minimum Span Tensile Pursantage It is the parameter that determines the minimum reinforcement to be placed in the tension zone in the beam. This parameter is used at the bottom in the span of the beam and above the beam support. Minimum reinforcement, Asmin=MinPullingPursantage* bw * (hd ) as h is calculated. Also, romin >=0.8 fctd /fyd condition is checked. It would be useful to review the technical manual of the program."proisa":3jb3aa3h" said:I have never seen this setting change automatically in the beam parameters menu... Since this value is valid for both C25 and C30, I manually enter 0.003. If I don't enter it myself, whatever material class I choose, it stays at 0.001 and 25/ It can give 2Q14 flat reinforcement in a 60' beam.

Curious friend, I don't understand what you mean. I'm not sure we're talking about the same thing. There is no minimum value other than the minimum opening pull margin in the beam parameters. If the span reinforcement is smaller than the TS500 minimum value according to the section calculation, the only parameter controlling this is the minimum span tensile reinforcement parameter TS500 formula, this can be given automatically because it only depends on the concrete and steel used.
The minimum value (0.8 fctd /fyd ) in TS500 is automatically controlled while determining the reinforcements separately for each beam. In addition to this check, a second check is made with the value entered by the user in the beam parameters and the larger of the two is taken as the minimum pursantan of the relevant beam. The program does not change the value in the beam parameters according to the concrete class, because different concrete classes can be defined for different beams within the static material logic.

In V7.017 a minimum working 30/50 beam, Concrete C25, Steel S420, when the concrete cover= 4.5 cm, the minimum reinforcement is 3.49 cm2 at the support and the span, 2fi16 reinforcement is selected in the pileless design Asmin = 0.8* (118.967/37241.81) * 30 * (50-4.5)= 3.488 cm2 Your concrete cover value in beams The beam may be running backwards (there may be no tensile moment in the lower part of the section in the span)... If you add the project, we will examine the situation?"proisa":3r4xfl8x" said:As you can see, there is 2Q12 flat reinforcement in a 30x50cm beam... Less than TS500 Concrete C25, Steel S420 V 7.017

If you look at the moment diagram of the K19 beam and the frame in which it is located, a reverse moment has occurred in the beam, in the vertical loading ... Therefore, reinforcement is not made according to the tension reinforcement bracket at the bottom. However, you can adjust the amount of reinforcement using your engineering initiative. (It is useful to increase the mounting reinforcement according to the reverse moment value at the top in the opening.)
Concrete cover, on one side of the section, longitudinally is the distance from the center of the reinforcement to the outer face of the section."proisa":vi9zbozu" said:And in the parameters, is the concrete cover on one side of the section or the sum of its two faces?
