Dear all, The fiber section is always used to model the RC beam/column. It can only work for tension, compression and bend due to each fiber containing a UniaxialMaterial. How does the fiber section work for shear condition? In the OpenSees document, section Aggregator can aggregate previously-defin...

Thank you for your reply. I'll try this

Dear all, When I used the command "section Elastic $secTag $E $A $Iz <$Iy $G $J>" to define a section for a nonlineareamcolumn element, How can i record its stress and strain of this section? In the recorder command "recorder Element -file ele1sec1StressStrain.out –time -ele 1 section...

remove loadPattern $tag

[quote="zeynepp"]Thanks for the reply. And is there any command to check stresses or strains? Actually the idea in creating that Matlab output was to check the strains at some locations in a fiber section. I want to check the strains that I get using recorder command during but not after t...

Hello, I do a transient dynamic analysis using the series load. The result seem to be wrong. The analysis model uses the Example 1. cantilever 2D. After the gravity analysis, the transient analysis code list as follow: ########################################## rayleigh 0. 0. 0. [expr 2*0.02/pow([ei...

That is OK. In first floor I have posted the integrated code. This example is based on "Ex1a.Canti2D". The transient analysis parameters is the same as "Ex1a.Canti2D.EQ". I just change the "pattern" and "analyze" parts. The point is how the transient analysis ...

Silvia,
I have sent the script to your "silvia at peer dot berkeley dat edu"

Thank you!

Silvia,
I have tried it using "Ex1a.Canti2D". The response of free node 2 is different due to these two ways. I'm confused on this. I don't know the reason. Could you help me to figure out this problem?

Thank you very much!

Sorry about that. The question is: *(1)We can use the Series command to execute a dynamic history analysis under a series loading. Such as: set DtAnalysis [expr 0.02]; # time-step Dt set Nstep [llength $loadlist]; pattern Plain 100 "Series -time $DtAnalysis -values $loadlist -factor 100" {...

Hello everybody, I try a simple example to understand the dynamic history analysis, the odd result comes out. In the test, I decompose the whole series to several series and use "for-loop" to connect them again. The testing model is "Ex1a.Canti2D". Does anybody know the reason of...

Thank you very much!

I have not find this kind of command yet.
Does anybody know this?

Hi Silvia,

I'm sorry I don't know how to find the updates for the latest version of OpenSees. Could you tell me? By the way, where can i find the new command list and help document?

Thank you very much!

Thank you very much! I have passed this problem. However, another problem comes out. The "nodeDisp" command can get the displacement or rotation at specified node. Does OpenSees have this kind of command returning the velocity at specified node? such as "nodeVel"... The node reco...
