Raft foundation-Superstructure interaction

[Erdem]

Hello, I had a question about something. There are direct connection and enlarge connection area tabs under the raft foundation superstructure interaction title in the idestatic analysis settings in the foundation floor section. In which projects are direct connection tabs or large tabs of the connection region used? What is the criterion? I would be glad if you help.

Hi, I had a question about a topic. There are direct connection and enlarge connection area tabs under the raft foundation superstructure interaction title in the idestatic analysis settings foundation floor section. In which projects can you choose the direct connection tab or the connection region? large tabs are used. What is the criterion? I would appreciate your help.

This parameter is effective in beamless raft foundation systems. The stresses occurring in the finite elements should be examined. The higher the raft height, the more effective it will be. If you choose direct connection, the column raft finite elements are equal to the column width. If you choose the connection area large, you will spread the sudden stress jumps in the column regions to a wider area.If the ground stress shows sudden jumps around the column compared to the general structure, you can choose the connection area as large.
