Short Beam Problem

Hello, there are short beam problems that I usually encounter in my projects. In general, I could fix these problems by changing the diameter, number or beam dimensions of the body reinforcements, but I could not fix 3 beams in the project I am currently working on. Can you help me with this, I couldn't load the project from the plugin, so I uploaded it to a separate site

Dear Colleague, If the attached alternative solution does not pose a problem architecturally, it may be preferred, you can fix the insufficient reinforcements in a few floors now! Greetings G.KOSE
 
DUE TO THE HIGH CUTTING FORCE IN SHORT BEAMERS, THE MUCH MUCH YOU ENLARGE THE BEAM DIMENSIONS, THE LARGER DIMENSIONS WILL BE INSUFFICIENT. IN SHORT BEAMERS, IF YOU INCREASED THE DIAMETER OF THE BEAM STOCK AND REDUCE THE STOCK SPACES, THE BEAM DIMENSIONS WILL BE SUITABLE. IN YOUR PROJECT, THE SOLUTION WAS PROVIDED BY MAKING THE SIZE OF THE K47 BEAM 30/60 AND MAKING THE STRAPS F14/10.
 
I was wondering who suggested this solution to you, in fact, the value you change is a parameter that is automatically calculated by the program and directly affects the analysis. Your solution should be to reduce the stiffness of the short beams so that the support moment assumed by the beam is reduced. G.KÖSE

mrb friends I solve short beam problems by doing beam-static-d1=1 good work everyone

Hello, by interfering with d1 parameter, you can change beam's rigid arm length. In my opinion, it is not the right approach to interfere with the rigid arms of the beams attached to the columns and panels. If the structural system cannot be changed, perhaps the cracked section rigidity can be used, considering that the beam cracks under earthquake loads. Good work
 
Hello Mr. Levent, can you explain the subject of d1:1 a little bit, what happens when d1=1, what happens when d1=0 or d1=0.5. Is this the same as the rigid zone factor logic in column beam junction areas in Etabs... Thank you..
 
d1: It is the distance parallel to the X-axis of eccentricity between the theoretical joint point of the left end of the beam and the left end of the beam in beams. d2: It is the distance parallel to the X-axis of eccentricity between the theoretical joint point of the right end of the beam and the right end of the beam in beams. If d1=1 is written, the left end of the beam is shifted 1 cm to the left from its theoretical point, and if d1=0.5 is written, 0.5 cm to the left. If d1=0, beam length and rigid arm distance are the values automatically determined by the program.
