recorder Drift -file $outDir/story_drift.out -time -iNode node@col_butt -jNode node@col_top -dof drift_direction -perpDirn direction_orthogonal2drift;

Works perfectly.

Thanks, Frank!

1.) I am running on the HPCC at the University of Notre Dame. I talked to the cluster admin and made sure they had built the most recent version of OpenSEESMP on the cluster. He suggested running the same code on the PEER cluster at Purdue but I haven't had the time to figure that out yet. 2.) Sorry...

Hi Frank, I have been using envelope recorders to extract peak demands as well as drift recorders with a specified recording -dt to obtain residual drifts and I've noticed some oddities and inconsistencies that I was hoping you could shed some light on. 1.) I am using an EnevelopeElement recorder to...

Thanks Frank, you should have an e-mail in your inbox with my scripts. If you have any question please don't hesitate to ask.

Thanks,
Andrew

OK Frank, I would appreciate that very much. How would you like to go about getting me your e-mail address? I assume you probably don't want to post it to the message board, haha.

Hello, I am performing close to 5000 dynamic analyses in a "for" loop and for each analysis the only thing that changes is the input ground motion. I have a very simple 2-D model with 2 dof from which I am outputting maximum story drifts and floor accelerations using the EnvelopeDrift and ...

Vesna, I am creating an asymmetrical cross section in 2D space. I am connecting a Nonlinear Beam Column Element with an asymmetrical cross section to the bottom edge of a rectangular panel frame. For simplicity of the model I would like to connect the NL BCE to the centerline of the frame. However, ...

Yes, I am trying to combine them as best as possible but I need to have many of the nodes and elements separated for post processing purposes. I'll try moving to a linux machine.

Thanks,
Andrew

Hello everybody, I was just wondering if there was a limit on the maximum number of recorder objects that can be used during an analysis. I have a script that creates a large number of recorder objects but after creating about half of them it appears that OpenSEES just gives up on creating the rest....

I am running a reverse-cyclic pushover analysis of a wall panel model using the files from Example 4 (specifically “LibGeneratePeaks”) on the OpenSEES website. I am able to run a symmetrical reversed cyclic pushover (with “CycleType” set to “Full”) for multiple peak displacements in both directions ...

I am also looking for a better definition for the input parameters of the Pinching4 Material. I have visited the material webpage on the OpenSEES wiki and read the attached PEER report but have not been able to find a thorough definition for what each of the parameters actually does with regards to ...

Please note:

The line that reads "section Fiber $HorizontalFiberTag {" Should read "section Fiber $FiberTag {" but that does not affect the ability of the code to run.

Thanks,
Andrew

I'm having trouble running a displacement controlled axial compression/tension test on a fiber element. The code is configured to run with an elastic material right now but I would eventually like to test a Concrete04 fiber element. Can someone please provide some insight as to why this code will no...

I am trying to develop a simple model of a totally hinged frame of rigid elements that only uses diagonal braced members for lateral resistance. Can someone please give me some advice regarding the simplest way to build this model. For example, which elements to use and how to ensure the end of each...
