Reinforcement build-up in elevator bulkhead and beam connection

[hydrkrmn]

I'M RECEIVING EXCESSIVE REINFORCEMENT BUILDING ON THE BEAM IN THE COMBINATION OF COLUMNS AND SCREENS. I CAN'T SOLVE WHAT I DID. I WAITING FOR YOUR HELP I ADDED THE PROJECT. THANK YOU

IN THE SAME WAY, THE SAME PROBLEM GETS K08 BEAM

I did not check the data, but your problem seems normal to me. Since the beam is short, the shear force is higher than the other ductile beams, and the beam behaves brittle. Therefore, reinforcement piling up can occur, usually in the form of body reinforcement.

Exactly, this is a normal situation, it happens in beams connected to the curtain, there is always an 85 percent stiffness reduction event There is also a tab called freedoms in the beam properties window. Can we use this tab for this type of beams? I want to ask the admins

Basic interaction, but superstructure- Hello, Structure system, superstructure- not defined in the appropriate model for the interactive solution. The elevator perimeter at low elevation and the continuous foundations connected to it from the upper level do not behave in harmony with each other in the 3D model. Therefore, the beams attached to the curtain receive more force than expected. TK22-T21 foundations are suspended in the air. TK26-TK09-TK17 foundations are in the S65 column The foundation of TK108, which is connected to each other at another point on the right, is defined on the curtain. It does not contribute to the system. For a solution, it may be appropriate to make a complete raft of the system, and for the elevator shaft, it may be appropriate to arrange the drawings according to the following information.

Duration If a double foundation is to be made, the whole structure must be connected to each other by continuous foundations. This is valid for version 7. There is no problem in 8 versions.

Hello, For beams located between two curtains, the program automatically reduces the stiffness of the beam by 50% (if marked in the beam settings) If the beams are supported on one side to the curtain, the stiffness reduction is not applied automatically. If it is thought that the beam will crack, that beam can be given freedom on its support.
