Plot Moment vs Rotation for THA in ETABS 2013
Plot Moment vs Rotation for THA in ETABS 2013
(OP)
Hello,
I am doing a THA on a simple 10-story Shear wall structure (10ft long) in order to get familiar with the software cause
I will then advance to performing more complcated modeling on rocking SW on foundation. Anyways, I submit
this structure to a THA, and I defined a Generalized Displacement "x" as the sum of the vertical displacement of the
2 joints in the 1st story extreme nodes and devided the sum by the length of the wall (one with + and the other with - sign), in
other words:
teta = (delta1 - delta2)/L (because they have opposite signs)
I also defined a section cut at story 1. I run the analysis, everything converge. But the problem arise when I try to use
the Display> Plot Function, I cannot select any Generalized Displacement already defined to be vertical or horizontal axes.
The problem is that the option that I get in "Plot Function" only let me select displacement at joints for the axes, but cannot
figure it out a way to assign the generalized displacement to the axes. With the section Cut there is no problem, I can perfectly
assign the Moment for the axes.
Do you have any suggestion to overcome this problem?
