Hi, Your project needs to add curtains in the y direction. Especially the upper right corner of the project is problematic. (In the project where you stated that you added curtains, the curtains you added in the x direction do not contribute to the structure at all.) In addition, the 4-meter elevator floor (which is arguably the elevator floor) negatively affects the relative floor drift control. We cannot see the contribution of the U curtains (which you should define as a group) on the left side of the building alone to the structure. If you can put similar curtains on the right of the building, it can contribute to the system as it will be more symmetrical. In the current relative story displacement report, Ey -5% large values appear: If you look at the displacement at the Ey 1 loading of the structure, you can observe this behavior: For example, if the K7 beam on the x axis is all floors, you will see the difference, but you will still need to add a curtain in the y direction. According to this information, if necessary, you should discuss the situation with the architect and review the carrier system of your project:
