SOME PROBLEMS ENCOUNTERED

[muhendismy]

1- During the placement of the perimeter curtains, which are only in the basement, is there a difference in attaching the curtains to the column nodal point or to the column surface, or which one should be done? 2- In raft foundations designed as slabs, there is a requirement to design a column head for the foundation and to write the thicknesses and analyze it so that this head remains inside the foundation. Regarding this issue, I saw that the 40 cm slab did not save the foundation, but by designing the column head, I saw that the foundation was saved. Isn't this a trick of the program at some point? Or does the program really need a design like this for the plate raft foundation? 3- Lastly, it is desired to design a raft foundation for a building with a building importance factor=1.4 floor=10 t/m² floor area of approximately 600 m² basement+floor+1+2. What would you recommend for thickness selection, would you recommend plate raft or beamed raft? Thank you...

1- During the placement of the perimeter walls that are only in the basement, is there a difference between attaching the curtains to the column nodal point or to the column surface, or which one should be done? There is a condition that the thicknesses must be written and analyzed so that they remain within the foundation. Regarding this issue, I saw that the 40 cm slab did not save the foundation, but by designing the column cap, I saw that the foundation was saved. Isn't this a trick of the program at some point? 3- Lastly, one of our engineers is to design a raft foundation for a building with a building importance factor=1.4 floor=10 t/m² floor area of approximately 600 m² basement+floor+1+2.What would you recommend for choosing the thickness of the plate? Would you recommend a raft or a beamed raft? Thank you...

Hello 1- There is a difference between the two methods. there is no k. If you examine it from the 3D frame, in both cases the system is modeled as it should be. 2-The situation you mentioned, in 5 versions, there was a requirement to define a column cap under the columns in order to control stapling on slab raft foundations. However, when defining these column headings, the table height and table dimensions must be 0. In this way, we make stapling control without affecting the raft basic results. If you give dimensions to these elements, you define a title above the foundation. Of course, that element affects the Basic results. There is no such need in 6 versions, stapling control is done automatically. 3- Apart from the ground information, plan and column layouts are also important, I cannot give a definite answer to this. In both conditions, the system can be entered and tested. if soil stress problem does not occur, it can be compared in terms of labor and cost. Good work
