Dear everyone, I have problem on the stress strain plots for the defined Steel02 material when the initial stress value isn included. I have defined Steel02 in BuildingTcl and use the test to see the material behaviour. However, when the initial stress value is included, the whole stress-strain beha...

Hey all, I need help for running OpenSEES on Mac. Could anyone help me on this? Step by step because I am new to this system. PS. I have write the model files by using tclEditor in Windows OS. Is there any possiblity I can transfer directly to Mac so I can use them to run on Mac straight away?? Than...

Dear all, I just have problem for using the Recorder to record the element/section stress strain. Based on the manual, the command is recorder Element -file -ele # section # fiber y z <mat> For my section model which I use fiber section and I subdivide the flange and web into many discritizations so...

Thanks very much, yigitozcelik

I think I just mixed up these two columns (I was using globalForce and thought that the first column was axial force)

Thanks very much for your time.

Dear yigitozcelik, I think I kind of figure out what wrong with my code. I would like to know what are the parameters represented in the results file. For element recorder, it can records both local element force and global force. i.e. recorder Element -file LHC1.out -time -ele 1 localForce(globalfo...

Dear yigitozcelik, Here is my Script file. Noted that I have subdivided each member into 8 sub-elements # OpenSees Frame 2 # Two-bay one-story Frame # ___________________ # | | | # | | | # | | | # 3m 7m # pin fix pin # # Units: kN, m, s # -------------------------- # Start of model generation # ----...

Dear yigitozcelik, I have built the model as the example shows with master and slave node. My model is a 2-bay 1 story frame. The support are pinned, fixed, and pinned for left column, central column and right column respectively. i.e. ____________ <---H | | | |LC |CC |RC | | | pin fix pin The pinne...

Thanks and really appreciate those comments. I just want to ensure that my method is corrected. I use an initial out-of-Straightness with a sinusoidal shape by changing the nodal coordinates. Is it the right way to impose initial out of straightness effect?? Another question is that how would I make...

Dear All, I am now analyzing a 2D single steel I-Section or W-section using fiber section with pinned at bottom and roller at top( free in vertical direction but fix in horizontal direction). A vertical compressional load is applied at top. I wish to obtained the elastic buckling force but seems Ope...

Hey all, I am now analyzing the steel frame that consider the steel residual stresses due to manufacturing. I have look up many examples to see if there is way to incorporate this. However, I couldn't find any way to do this. I would like to incorporate the residual stress distribution such as ECCS ...
