Why doesn't the Beam Maximum Separation Exceeded warning show?

[qwerty]

Dear ide, When we manually intervene in the reinforcement of a section of reinforced concrete, does the program check according to the regulations according to the new reinforcement? When we intervene in the tensile reinforcement, does it control according to all the criteria related to the reinforcement requirements of the beams? For example, reinforcement ratio <0.02 , <0.85r pressure, >0.8*fctd/fyd, "At least one-third of the tensile reinforcement in the span must be extended and clamped to the support.", "The maximum support upper reinforcement at both ends of the beam At least 1 in 4 will be continued continuously along the entire beam. " Especially when we intervene in the pressure reinforcement for deflection, does it check whether we exceed the pressure value of 0.85r, which is the pressure break threshold? There is an example of a beam in the picture, and I couldn't understand why the program was not giving a warning.

When we intervene in the tensile reinforcement, does it check according to all the criteria of the regulation related to the reinforcement conditions of the beams?

Hello, manual reinforcement is user initiative. Maximum price control for the intervened reinforcement is not done in the program, however, if less reinforcement than the required reinforcement is entered, the program gives a warning.

Mr. Hakan, is the program not checking the maximum price because we are interfering with the equipment manually? Or in any case (manually or not) it does not check the maximum price? If the program does not in any case do the maximum price control according to the balance <0.85*ro, we, the users, have to do this control. (Note: In the description of the beam parameters, it says that it is controlled only according to 0.02) As you know, we should not exceed 85% of the balance reinforcement ratio (ro balance). (<0.85*ro equilibrium). Here the user will find and control the ro pressure for the opening and supports. So, is there an easy method you can recommend, as it will take a long time for the user to do this for each beam? Note: When we perform analysis after interfering with the reinforcement in the reinforced concrete dialog and locking it, it does not give a warning.

Hakan Bey, is the program not checking the maximum price because we are interfering with the equipment manually? or Does it not check the maximum price in all cases (whether it is manually intervened or not)? If it doesn't, we the users have to do this check.As you know, we should not exceed 85% of the balance reinforcement ratio (ro pressure).(<0.85*ro pressure). When we increase the reinforcement ourselves in the reinforced concrete dialog, the maximum allowance is not checked. In addition, the situation "the difference in the tension and compression reinforcement ratio in beams cannot be more than 0.85 times the balanced reinforcement ratio" is not checked in the program. It is among our notes to check it. The need to increase the reinforcement is not a situation that is normally applied because the program is designed Automatically select the reinforcement that is sufficient according to the design moments during the ar. If the maximum purchase price is exceeded during the reinforcement selection, the user is warned.

So, is there an easy method you can suggest since it would take a long time for the user to do this for each beam?

I don't think the number of beams that need to increase reinforcement in a project will be large. Beam dimensions are generally standard in the project. If you calculate the maximum amount of reinforcement in "As" according to the beam dimensions and the reinforcement cover, this value will help you during the intervention.
