plastic hinge based on modified Ibarra-Krawinkler

Post by setareh20 »

Hi,
This is one of my beam hinge definition based on modified Ibarra-Krawinkler model and after that there is a table that shows beam rotation history in time history analysis output.

For comparisons results between hinge definition and beam rotation history in time history analysis output, I should compare absolute value of negative rotations in time history analysis output with th_pNeg ,th_pcNeg and th_puNeg in beam hinge definition and positive rotations in time history analysis output with th_pPos ,th_pcPos and th_puPos in beam hinge definition respectively. Is it true?

Beam Hinge Definition:
set McMy 1.13
set n 10
set LS 323.115
set LK 0
set LA 0
set LD 323.115
set cS 1
set cK 1
set cA 1
set cD 1
set th_pPos 0.05
set th_pNeg 0.05
set th_pcPos 0.0387
set th_pcNeg 0.0387
set ResP 0
set ResN 0
set DP 1
set DN 1
set th_uPos 0.0967
set th_uNeg 0.0974

I am not sure I understand your question. Can you describe your problem again?

For analysis of the result (Beam Rotation History in Time History Analysis Outputin above) figures have + and - signs. I should compare figures with + sign in result with the th_pPositive ,th_pcPositive and th_uPositive in Beam Hinge Definition in above and also figures with - sign in result with the th_pNegative ,th_pcNegative and th_uNegative. Is it true?
