Junction Zone Interrupt Security

[dogukan]

Have a nice day; After getting a shear safety error in the junction area in my project, when I check the double stirrup option for the beams in the relevant direction and make a reinforced concrete design again, the problem disappears, but the reinforcement area (As2) coming to the junction area, which I do not understand, decreases. What is the reason for this?

Good afternoon; After getting a joint zone shear safety error in my project, when I check the double stirrup option for the beams in the relevant direction and make a reinforced concrete design again, the problem disappears, but the reinforcement area (As2) coming to the joint area, which I do not understand, decreases. What is the reason for this? ?

Double stirrup option can change the reinforcement selection in beams. After re-analysis for both cases, compare the existing reinforcements in that support. You can see the difference after this comparison. Also make sure that there are no outdated As messages in the beams.

It is possible to select only one type of reinforcement, with the options of 14 for assembly, flat and pile, and 12 for additional, marked. Only one type of reinforcement is selected. can it affect? Stirrup does not have any effect on the longitudinal reinforcement calculation, I could not find the connection?

It is possible to select only one type of reinforcement, with 14 options for assembly, flat and pleat options and 12 for additional options. I don't fully understand how As2 in regulation equation 3.11 changes with double stirrup selection. Stirrup increases the shearing capacity of the beam, how can it affect the longitudinal reinforcement area? The stirrup has no effect in the calculation of the longitudinal reinforcement, I could not find the connection between them?

The number of assembly and flat in beams is arranged to correspond to double stirrup folds. This arrangement can change the number of reinforcements. the previous one has additional reinforcement on the common support, the next one does not, the current reinforcement values may have changed (Confirm that there is no missing Ace message on the beams. If there is no missing ace message, the selected reinforcement will never be the required one). If you add both of your projects, we will review and write a more precise answer.
