hello everyone!
Plasticity contains Distributed plasticity and Lumped-Plasticity .Now i want to analysis a cantilever column ,fistly should build model, if i choose Lumped-Plasticity ,How to define plastic hinge? if you have script about plastic hinge, can i share with you ?
thanks !

dinochen1983, thank you very much !

now ,i am in the difficulty ,please help me out! thanks!

[url] [img] you need to build it up using rectangular cross patches or use a graphical tool like xtract, OpenSees can actually read an xtract file. hello fmk! now i want to build a column with irregular section ,at the middle of which is a rectangular ,two sides of the rectangular are half circles. ...

Thanks silvia! :) If i calculate damage in post-processing,should i use OSP - The OpenSees Graphical Post Processor ? If i want to get hysteretic curves,should i define two ecorder command in the Reverse Cyclic Lateral Load Analysis ? the two ecorder command are : recorder Node -file RCyclic.out -ti...

Thanks silvia! but now i am puzzled. time is the analysis time, whether static or dynamic. then,should the analysis time be positive? but recorder Node -file RCyclic.out -time -node 2 -dof 1 2 disp , some part of out data is : -0.035528 0.0001 2.39744e-006 -0.0722387 0.0002 5.68205e-006 -0.121565 0....

Hello everyone! Please help me out In the manual,Node Recorder command is that recorder Node <-file $fileName> <-time> <-node ($node1 $node2 ...)> <-nodeRange $startNode $endNode> <-region $RegionTag> <-node all> -dof ($dof1 $dof2 ...) $respType -time : this argument will place the pseudo time of th...

Hello,divamva! I have two question about your Message of Displacement control fails with SDOFs having negative slope.In this Message ,there is a note: # NOTE here: IF you include -load or -time, you also get the axial load output. If you do not, then # you only get the nodal displacement! recorder N...

thank you silvia! now i have two question 1. in the RCyclicPinch.tcl ,how to get the parameter for example rDisp ,uForce,gammaK1 gammaK2 gammaK3 gammaK4 gammaKLimit ,gammaD1 gammaD2 gammaD3 gammaD4 gammaDLimit ? ##### Ratio of maximum deformation at which reloading begins ### Pos_env. Neg_env. set r...

hello everyone! I am a graduate and a greenhand of OS. Thanks in advance! I want to do Reverse Cyclic Lateral Load Analysis and damage of cantilever column. Reverse Cyclic Lateral Load Analysis script is: wipe source gravityloads.tcl pattern Plain 2 "Linear" { load 2 200 0.0 0.0 } uniaxial...
