Pile Modeling

[kyuceturk]

Hello, I need to use a piled raft system for the structure I am solving. For this, first of all, is there a document about idecad's piled raft modeling management? 1. The issue I am particularly curious about is how does it models the vertical stiffness of the pile, is it fully rigid, does it model it as an approximate method (combining the surface impingement and base resistance) or does it consider these points as rigid on the raft. 2. The area where my piles will be located is a very low cohesive soil and is cohesionless in places. But as I understand from the definition of soil layers, piles can be defined for cohesive soils. Can I define a pile for cohesionless soils from a part that I cannot see? 3. For my piles in cohesionless soil, can I get the correct result if I find the equivalent spring coefficient of the whole pile and enter the soil spring coefficient section in the soil layers and take other parameters as 0? Since Idecad only models driven piles, can I calculate the bored piles approximately in this way? Thank you, Kutay Yuceturk
