Earth Curtain Design

[merus]

Hello, I am interested in a project prepared in the İdecad program. I have a few questions. Since I do not know the working logic of the program, my questions may seem a little absurd. Don't mind me. I would be glad if you could answer what you can. 1) When creating soil-propelled combinations in the program, is the content of these combinations vertical+soil or vertical+soil+earthquake effect (or both separately)? 2) In this program, is the effect of the earth thrust on the earth curtains the same as in SAP2000? In other words, we define the loads and soil thrust combinations, enter the load amounts/affect the load to the element. How then does the program determine which combinations to use in earth curtains? 3) What is the exact way I can decide whether soil thrust is effected on basement curtains in the program? 4) Regardless of the program, when we design according to the most unfavorable combination of vertical+soil and vertical+earthquake, can we generalize that the soil thrust at these shears will always be more unfavorable than the earthquake effect (or vice versa)? 5) Again, regardless of the program, isn't it insufficient to design according to the most unfavorable combination of vertical+soil and vertical+earthquake? Shouldn't we design according to the vertical+soil+earthquake combination?

Hello, -The process of defining soil load on the panels is explained in the link below.

-TS500 clause 6.2.6 states which loading combinations should be made in case of lateral soil thrust. Good work
