Pressure or Force in lateral loading conditions?
Hello everyone, I am simulating a RCC Column subjected to axial load at top and lateral displacement at some distance from top. Now i am wondering what kind of behaviour will be exhibited on a column having load of 4 stories above it? Should i consider it as pressure load or axial load on face. I am getting different results with both the cases and hence I am a little confused.
Here's a picture for reference along with graph.
