you are more than welcome

No I did not try Adaptive pushover,I did Modal pushover instead. As I explained to u earlier, the material or hysteretic behavior of SDOF depends upon the response of Multimode full structure.. first u have to run a reversed cyclic Pushover analysis then after examining the hystertic loops it will b...

welcome there is no need to apply any axial load for SDOF..u can remove that OR even if u keep it zero it doesnt matter

you can easily modify this code, if you want to use bi-linear relationship,just replace the uni-axial hysteretic material with a bi-linear one

I have use uni-axial hysteresis material for SDOF. Then I have assigned the Fsn/Ln - Dn relationship to a zerolength element with unit mass..here is the code,let me if it is not working.. # units: N, m, sec wipe; # clear memory of all past model definitions set val1 [clock seconds]; file mkdir Data;...

You are welcome..Actually the choice of SDOF Idealized mode depends upon the hysterics behavior of your structure..U have to run Reversed cyclic Pushover analysis to get an idea of hysterics response of ur structure..By looking at hysterics response if u thinks that bilinear model is suitable for th...

you are more than welcome

Hi vesna..Thank you for ur reply..I need to calculate moment at each story,in static analysis its simple to get the moment by multilying the total height with Fx,but in time history analysis it wont be like that I think,because center of resultant force can shift downward.Thats why when I calculate ...

hi hjxiang and Vesna.. I also want to apply the Reverse cyclic history on a certain in my model. I did the same as you( hjxiang) have done,but when I look at the results it shows that displacement is increasing monotonically not as i write in my dispalcement history(i.e reverse cyclic). Can you plea...

Thank you Vesna..I got it..I have another question, I am having problem using 4 nonded Quad elements. Its a 2D model of a shear wall. Since it is a 2D model it gives my forces in x and y directions only. Is there any way I can get moments? I have done a time history analysis using Quad elements,so p...

hi sghanea here is an example for a 30 story shear wall for modal pushover analysis. wall is model by using non-linear beam column elements. you can see that the in pattern Plain 2 Linear lateral force (Sn1=m*phi_1) has been applied and then the wall is pushed upto 1% drift. For 2nd and 3rd mode rep...

Hi aslam... r u from Pakistan? from NED Karachi? Im Tahir from Pakistan,right now studying in AIT,Bangkok..If you need any help feel free to contact,my e-mail address is civilengr_tahir@hotmail.com

Hi vesna and everybody else... I have a done a eigenvalue analysis,after getting the values of shape factors, results shows that for 3rd mode,shape factor is higher in the mid height of my structure than the shap factor value at top node,It seems unusual to me,Is it right or wrong?can any body help me

hmmmmmmm Nobody is there to reply?

Can anyone help plzzzz
