Column Shear Safety Control

[profesyonel]

Hello, in my attached project and the like, I cannot see the clear height of the basement floor and the ground floor, column shear safety control separately. The column gives the clean height according to the total floor height of the basement and ground floor. I get the same result if the sub-basement is rigid or non-rigid. Even solving the project as tamrigit or shell does not change the situation. Building inspection companies want to see the clear height of the basement and ground floor column separately in the column shear force control, but they create problems because they write the total height. I request you to revert to the issue. good forums

Hello, Curtains are not modeled as shells in your project. For an accurate calculation, analyze the properties of all your curtains by selecting the "Model as Shell" option in the Static Reinforced Concrete tab. In addition, since there is no diaphragm (floor) in the sub-basement floor, it would be appropriate not to accept the floor as rigid. In your project, the Ground class Ze type is a weak ground and the Design spectrum value is quite large. When the curtains are modeled as shells, a relative floor offset problem occurs in your project. You can review the knowledge base link below for the relative floor drift problem and possible solutions.
