Hi run the example of Ex2c.Canti2D.InelasticFiberSection.EQ, I plot the hysteretic curve with the base shear and and the displacement at the deck level,but the hysteresis loop looks like a line ,it doesn't look like the usually hysteresis loop i saw in many publications. can you tell me what's wrong...

hello Fame
wish you to see my message .
my hysteresis loop looks like unusual,i don't know what is the matter with the model of bridge column , please give me some advice ,thank you!

best wishes

hello Fame
i meet the same problem,how did you do that? please give me some advice thank you!

hello,everyone!
there are many hysteretic models in opensees,and the hysteretic models usually define by the class of materials ,which order is define the hysteretic models ? may be should i define a hysteretic material at first?
best wish.

i meet the same problem,and the code stop running at the time which is ont the ground motion end time. > Hi > Here is a part of the warning message about convergence problems that I have due to > time history analysis: > > OpenSees > analyze failed, returned: -3 error flag > WARNING: CTestEnergyIncr...

to fmk thank you very much .when i check out the results and encountered a problem . there are two recorder of support reaction in my code ,one is " recorder Node -file ida/reaction1.out -time -node 1 -dof 1 2 3 reaction ",the other is " recorder Element -file x[expr $gmf]/ztele_1.out...

to fmk : i have an question about reyleigh damping factors,most exeamples show that the value of $betaKcurr and $betaKinit is 0,so i want to know how to define $betaKcurr and $betaKinit ,and What is the difference in using the $betaKcurr ,$betaKinit and $betaKcomm. fmk wrote: > the second analysis s...

to fmk: thanks,i move the loop to the start of the code ,the result is equal. fmk wrote: > the second analysis starts at the end of the first. if you want each to > start from 0 with the model at the initial state you need to move the for > loop to the start of the file and put in a wipe.

HE,ELi run the code ,i found that the result is different when i=100 and i=1 under the same Factor .

hi ,i wrote the code of IDA,i meet two problem ,1) in the loop , when $i=2 the ground start time is 28.01,but it should be 0.01; 2) the root displacement is different the $gmf=2.998 which wipe the loop, can you tell me what's wrong with the code? #“IDA CODE” #Units: N,m .Kg #Define model builder fil...

hello! I have been learnt paper,which is "Multiple Support Response Spectrum Analysis Of Bridges Including The Site-Response Effect and The MSRS code",and I am interesting MSRS code.So I look it for online,unfortunately, I found a connection but can not download software． The link is 'http...

to fmk: thanks so much! the answer is very detailed. there are a number of main subdirectories under OpenSees/SRC 1. Analysis - all classes associated with analysis are here 2. Element - all element types are under here 3. Material - all material types under here 4. Domain - all classes associated t...

thanks so much. I have been downloaded the code ,but the code has been divided into many parts,i don't know the part which is use for computing or simulation,would you please tell me ? thanks for your time ! go to the developer pages on the website. The last few releases of OpenSees can be downloade...

thanks so much !

how and where can i downlode the opensees source code?


thankes for your attention!
