Join Interrupt Security

Because of the two beams attached to the column in different sizes (25/60 and 60/32), I cannot ensure the shear safety of the junction area. I can't give any misalignment to the beam, I don't want to make the column thicker, it doesn't make any profit to interfere with the reinforcement order... However, after some thought, I came to the following conclusion. 1- Since the beam heights are different, the beam sub-reinforcements are already discontinuous. 2- In the upper reinforcement, half of the 60 cm wide beam reinforcements are discontinuous. Some will continue, some will be squared in the column. In other words, there is an approach towards the situation where As2 should be 0. The program, on the other hand, takes into account discontinuous beam reinforcements when calculating As2. This is why the interrupt security of the junction region does not save. When I uncheck the "Continuously accept beam on the right end" option, the problem disappears. But when you do this, the beam details are given separately. In reality, there should be partial reinforcement in the upper reinforcements. I would like to have your valuable opinions on the program's As1-As2 calculation and whether it would be a correct intervention for me to continually acceptme beams to deal with this problem. Respects.

I tried, but when I do it, it doesn't give the desired result. With the partial transition option, all beam reinforcements are always accepted. So As2 comes out high, while other options separate the beams completely.

I know these. I asked whether non-continuous beam reinforcements should be included in the As2 calculation. Thank you.

Different width arm We do not have the possibility to choose which reinforcements will be used in the partial transition in the beams connected to it, but if you apply the partial transition in the program, a partial transition is achieved with the algorithm described below based on the ratio of beam widths. Width of the joint part of the beams = the area covered by the 2 beams together Reinforcement passing from the 1st beam to the 2nd beam = (cm2 of own reinforcement of the 1st beam) * (width of the common part / width of the 1st beam) The existing reinforcement in the 2nd beam = the own reinforcement of the 2nd beam reinforcement + reinforcement passing from the 1st beam to the 2nd beam. If the beam is at different heights at the same time, the lower reinforcements are not passed to the other side, the upper reinforcements are passed within the ratio. After partial penetration, As1 and/or As2 values are calculated according to the non-passing reinforcements in column beam shear safety control and used in column beam shear safety control. Reinforcement amounts of non-transferred reinforcements are not included in As1 and/or As2 value in column beam shear safety control.

If the beams connected to the column of different widths have less common area in the column, the reinforcement may not be passed to the other side. The "continuous accept or reject" option of the beams in the beams reinforcement settings does not affect the analysis model. It only affects the reinforcement shape of the beams. The expression of continuousness refers to the other side of the reinforcement. It is the answer to the question of whether the transition will be made to the other side of the column or whether the reinforcements will be cut on the other side of the column. In any case, the reinforcement selection is made by the program to meet the design moment on the right and left of the column. According to the existing reinforcement, the column beam shear safety check is made.
 
"Reinforcement amounts of non-through rebars are not already included in As1 and/or As2 value in column beam shear safety control." I expected this to happen. It already was. I guess I miscalculated. Thank you.
