Hello I was confronted with an error like below. Please help me to solve that. Thank you . . . Congratulation !!! , Columns & Beams elements defined !!!. T1 = 2.8525470262665253 s T2 = 1.3284507695399246 s T3 = 0.7244860760094864 s T4 = 0.47832734986163417 s T5 = 0.33289606817833733 s Congratula...

Hello thank you for your useful responses It goes without saying that incremental dynamic analysis in sophisticated models causes convergence problems and we need to add a solution algorithm, to eliminate these problems. I prepared an incremental dynamic analysis code using a for-each loop like this...

Hello you shouldn't use this command for 3-d models, because frist line of this Command_Manual states: "The MVLEM element command is used to generate a two-dimensional Multiple-Vertical-Line-Element-Model " http://opensees.berkeley.edu/wiki/index.php/MVLEM_-_Multiple-Vertical-Line-Element-...

Hi Dear, Thanks a lot for your reply. 1- I want to know locations of End node tags ($iNode and $jNode) in this command: Element MVLEM $eleTag $Dens $iNode $jNode $m…….. 2- How can I calculate Number of element macro-fibers($m) in this command? 3-I think a concrete shear wall just should be connected...

Hello Dear
I'd like to model a SELF CENTERING VISCOELASTIC DAMPER (SCVDs) (Karavasilis, Blakeborough et al. 2011) in opensees, with properties like attached file.

Could you please explain that which command i can use?
thanks a lot.

Hello Dear I like to use MVLEM Element Command for Modeling a RC Wall. Could you please explain about my opacities? 1- Why the height was separated to 17 points in the relevant (.tcl) code? In other words, I’d like to know that is node 17 for top of building or is for top of story? (MVLEM_RW2.tcl): ...

Thank you Dear, Thanks a lot.

Thank you Dear, Thanks a lot.

thank you dear

Hello Dear Silvia I used below code for IDA analysis with changing 7 Earthquake Records Using foreach loop. But I had this ERROR: [ Wrong # args: should be “foreach varlist list ? varlist list …? command” While executing….] Could you please explain about this ERROR? Thanks a lot for your kindness. :...

Thanks a lot

Hello Dear Silvia I used The Giuffre–Menegotto–Pinto steel material (OpenSees STEEL02 material) with isotropic strain Hardening for Beams, Columns and Braces in a bracing frame system. Could you please help to me about considering strain hardening for below materials? .................. uniaxialMate...

Dear, Thanks a lot for your quite complete response Now, I have some opacities, Please help to my understanding: 1- It means that in a braced frame we must apply all PDelta loads to leaning column’s nodes. Is it right? 2- I want to know about effect of this leaning column in Capacity Curve’s shape. ...

Dear, Thanks a lot for your reply. I thought that way is just for moment frams , Because I have following opacities in this field. Please help to my understanding: 1- we have a bracing frame that columns are pinned at bottom. Must We add leaning column for Simulating P-Delta effects with changing pi...

Heloo
Please Explain to me This Matter:
How do i Consider P-Delta Effects (Large P-Delta) in a bracing frame without Using Leaning Column Algorithm (Mrs-Laura Eads, Stanford University, 2010 ).
Because it Seems that way is Just for moment frames.
Thanks a lot
