Curtain Tipping Moment

Hello to everyone. 1-) When I make the curtain in one piece, the curtain overturning moment ratio is not 0.75, but when I divide this curtain into two and put a tie beam between it, the ratio is provided. As a result, the tie beam becomes a high beam (L/H<2). Is this beam a danger for the future? Shouldn't a single curtain give a more advantageous result than two curtains with tie beams? 2-) There are few curtains in the X direction of my curtain-frame project and the curtain overturning moment ratio in this direction is exactly 1.00. Is this normal or does it mean I made a mistake somewhere? 3-) Should the requirement of being at least 1/16th of the storey height for wall section thicknesses be considered for the height from the foundation or for the height of the part above the basement perimeter walls? Does it matter in which direction the other curtains are tied so that a curtain can be considered held? 4-) When I make the curtain in an L shape, is there a criterion for the curtain length in the short direction? I couldn't find it in the regulations. So one arm can be 30/200 and the other arm 30/60? Thanks in advance.
 
1) It is normal for the rafter curtain to take more overturning moment. 2) Although there are a small number of screens, it may be normal to have 1, to speak for sure, we need to look at the project. 3) The thickness condition is valid for the whole structure 4) If it is a one-way curtain, 1/6 condition is not required for the short arm. In polygonal curtains, at least one arm in both directions must meet the 1/6 condition.
 
Thank you for the answers. When I turn to the tie beam shear to achieve the 0.75 ratio, this tie beam becomes seriously "high beam". The tie beam, on the one hand, needs to be strong, and on the other hand, there is no high beam. It is not possible to provide both at the same time. Which one do you think I should neglect?
