Dear all,
I did linear buckling analysis in ETABS of a tall building under load case DL,SDL, and 0.25 LL as applied load. The modal analysis use eigen.
It happened that there is a warning on "no buckling mode found" during analysis result.
May I have your ideas and solutioins related to this...
Dear Trenno,
I have long column over that separate at 15 story height without divided at each story. I don't divide because I study Big mega column, and I assume that the flat slab is not sufficient enough to separate the columns effective length at each story.
Thank you very much for your...
Dear JoshPlum,
The floor level are not slopped. it is flat. Yes, the diaphragm takes in-plane shear as well. I use Auto-Wind load in ETABS. Would you mind explain more about move 0.1 inch left or right point load? I don't really get it.
Thank you very much for your response.
Dear engineers,
I modeled a building in ETABS, and under wind loading, then I got the result of story response forces like this.
The semi-rigid is assigned, and the slab are flat slab.
I wonder why the overturning moment and story shear force reverse the value from negative to positive value...
Dear Trenno,
Thank for your response.
I select all the core walls in all story and assign it as one pier [P1], then I check, and the results seem not logic.
Dear fellow engineers,
I have a question regarding the problem of checking the shear force between core wall and response story plot in ETABS 2016.
I check at the top location of story 75th, and see that the total shear force in core wall is bigger than the total shear force by story response...
