Dear form users and idecad officials who always try to help us, Can different foundation types (Single / Continuous / Raft etc.) be applied in the same structure? Are there any drawbacks to its application? Is it suitable for the working principle of the İdecad program? Or What does the user need to do to be eligible? Thank you and have nice work.
 
Thank you for your answer. I think it might be useful to open the following topic: Can different foundation types (Singular / Continuous / Raft etc.) be applied in the same structure? Are there any drawbacks to its application? İdecad "A fundamental analysis model has been developed to use mixed foundation systems in version 8.62." you said. It concludes that solving mixed basis in versions before Idecad 8.62 is not correct in terms of the capacity of the program. Is there an official explanation by İdecad that they can help with this issue as a whole? What does the user have to do in order for the İdecad program to be compatible with the working principle of the versions before the 8.62 version?
 
In ideCAD, different foundation systems can be used in the same structure. There are differences between versions in ideCAD Static. With version 7.20 ; Continuous foundation system, raft foundation systems can be modeled and superstructure can be solved interactively. The rafter raft system can be modeled. This model is made by modeling the continuous foundations as a grid and defining a raft foundation inside. Beamed raft foundations can only be solved without superstructure interaction. In these versions, beamed raft foundation systems cannot be solved with superstructure interaction. Your model does not fit them, you have a model of partial raft foundation and continuous foundations connected to raft foundation. This hybrid pattern cannot be resolved in versions 7 and older. 8.504 and later versions (currently version 8.62) Basic modeling methods have been developed since version 8.504. Except for the single foundation, all the foundation systems I mentioned above can be solved with or without superstructure interaction. In singular foundations, you can only solve without superstructure interaction. Mixed foundation systems consisting of continuous foundations connected to the raft foundation, as in your project, can be solved with or without superstructure interaction. Raft foundation and continuous foundations can be modeled together as desired. Program possibilities and newly added features are announced to our users with updates.

Dear İdecad family, We are using this form under your help and arbitration. We share our knowledge and do it in the comments to help each other. But we need your correspondence to be verified by you in terms of the program. Otherwise, our thoughts and conclusions about the program remain suspended. I request you to intervene not only when our posts are wrong, but also when they are partially wrong or partially correct. Thus, we will be able to use the program properly. We need your valuable ideas and official explanations.
 
Dear idecad family, can Idecad also apply Mixed foundation (Single, Continuous, Raft etc. foundations together) for the same building? Is it suitable for the working principle of the İdecad program? Or What does the user need to do to be eligible? Do Idecad versions have a different perspective on the situation? As you can see in the picture, a mixed basis (Continuous basis + Radey basis) has been submitted to us for review. In the raft foundation, the soil stresses show zero after the analysis. (Soil tension control is not or cannot be done) Legislation and Program requirement What kind of way would it be right for us to follow?
 
Mr. Yasin Tezel, I thought you were independent form members like us. Sorry, I just learned that you are an İdecad employee. So some of my questions have been answered. (Idecad has made an official statement) Then I understood that idecad users should not use the mixed base system before version 8. Is it true?

As I mentioned above, you need to use 8.504 and later versions for mixed foundations

As far as I can see from the picture, you are using 7 versions. In Version 7, it is not possible to solve such mixed foundations. Therefore, the soil stresses are 0. If a solution is made in versions after 8.504, the soil stress values can be seen. Good work.

Dear enginer_yildiz, The project in the picture you attached was sent to us by mail by our user with the question "As the basic system is raft and continuous, the relevant municipality requests your approval." "The model you created is incorrect in terms of data entry in the version you are using. Continuous foundations TK7-8-12-13-14 should not be used as the edge of a raft slab. The raft slab edge should be defined on these edges. Sample data entry is attached." was answered. You can learn the details from the project manager. Good work.
 
Thank you Mr. Yasin and Mr. Levent. Mr. Levent, Even though we create our raft floor with the floor edge, the system is still continuous + raft foundation = mixed foundation. and in the version used 7. Would it be correct to solve it this way? Because it was said by idecad that "you must use 8.504 and later versions of mixed foundations". I wish you good work.

Dear engineer_yildiz -Different foundation types can be used together in all versions. However, in 7 and earlier versions, raft foundation without beam system, continuous foundations cannot be used as the border limiting the raft slab. (This is what Yasin Bey means by the mixed foundation system.) I am writing which foundation systems can be solved in which version below. 7 version; - Different foundation types can be used together in the same project. -Rat foundations without beams should be formed with slab edge. Continuous foundation cannot be used on any side. Superstructure interactive/non-interactive solution structure it can. In rafter raft foundation systems, all columns and walls are connected to each other with continuous foundations. A raft slab is placed in the intervening chambers. No superstructure interactive solution is made. -Continuous foundations are formed by connecting columns and shear walls at nodal points. Superstructure can be made interactive/non-interactive solution. -Single foundations can be defined under the columns. The superstructure is made non-interactive solution. Good work 8 version; -Different foundation types can be used in the same project. -Rat foundations can be created by using slab edge and/or continuous foundations together. A raft foundation can be made by defining a continuous foundation only on the outer edges or on any edge. The superstructure is made interactive/non-interactive solution. -Continuous foundations are formed by connecting columns and shear walls at nodal points. Superstructure can be made interactive/non-interactive solution. -Single foundations can be defined under the columns. The superstructure is made non-interactive solution.
