Turkish The beam, which I have numbered 1-2-3 in the attached picture, is a single span beam that fits on the curtain at one end and the beam at the other end. According to what has been said on the forum, I should name the 1st part separate, the 2nd part and the 3rd part the same. When I give the same name, the beam exceeds the deflection limit, when I name it separately, it is sufficient. I think, when I give a different name in the deflection calculation, the support moment and clean span of the number 1 beam are used. Also, how would you interpret the moment graph to come out like this?

Mr. isbandam When you give different names or sizes of the beams given by adding them end to end; 1- Rigidity, center of gravity of the system, 2- Beam Deflections, 3- Moments, 4- Reinforcements are different. VERY IMPORTANT RULE: DO NOT ADD BEAM DATA WITH A DIFFERENT NAME OR SIZE. IF YOU WILL GIVE THEM THE SAME NAME AND SIZE. Take it easy.

Hello, The fact that the names of the divided beams in the program are different does not change the analysis results, namely the element end forces . It affects the reinforced concrete design. Giving the names of the two divided beams the same makes these two beams to be perceived as a single beam. Deflection control and reinforced concrete design of the beam is done as if it is a single beam.
I think there has been a misunderstanding. The beam, which I have numbered as 1-2-3 in the figure, is entered in the program as a single-span beam and at one time. It is recommended to consider the moment graph when naming beams, according to what was previously explained in the forum. Now, when we look at the moment graph of this beam, which I entered into the system as a single span (and at one time), the sign of the moment changes when passing from part 1 to part 2 of the beam. (I expected it to change on the right support side of the 3rd part).

Hello, Hello, There does not appear to be a problem with the beam results in the project. Make beam K313, to which beam K345 is attached, very rigid to get results close to what you expect. (For example, do 40/120.) Good work
