Concrete02 hysteretic behavior

Hello, I have a question... Where can I found information about the cyclic behavior and parameters for Concrete02? I tried with

http://nisee.berkeley.edu/documents/eli ... -loads.pdf

but I have no access there.

Thanks!

Re: defining moment rotation relation for members

Hello,

Defining the moment-rotation relationship for beams and columns is possible. Look at this:

Re: "patch rect" command

Dear Vesna, I have a suggestion. What you have written would be correct only if the rectangular fiber took place in the whole y-z plane, but if the fiber were only in a particular quadrant, then that wouldn't be absolutely OK. So what I suggest is to change 3th and 1th quadrant by something like thi...

Re: "patch rect" command

You are welcome, Vesna. By the way, in a recent post, I'm asking for the usage of composite response recorder or something like that, present in the last version of OpenSees. It says that can record information from all section in a beam-column. Can you help me please, giving me an example or the wa...

Re: "patch rect" command

Hello,

I'm still using "patch rect". I think it is easier for rectangular sections, because you only need two points.

Re: Strange seismic response on high frame building

Dear Vesna,

could I send the files to you and could you please take a look of them?

thanks!

Strange seismic response on high frame building

Dear Frank, My name is Felipe Cordero and I'm modeling wall buildings in OpenSees for my engineering thesis under the guidance of prof. Leonardo Massone, who has contributed to Opensees before. I've been modeling several 2D frame buildings, trying to explain the seismic behavior and the damage obser...

Re: concrete problem

Yes, you are right. I've been having problems on cyclic behavior. However, I'll be here soon with more questions and asking for help :)

Thanks.

concrete problem

Hello, I'm working with big fiber section models for my thesis. I'm running pushover and time-history analysis and I'm getting really rare results (rare deformation and base reaction about twice or more times bigger than pushover). Trying to figure out what is the trouble, I decided to see what is h...

observation

if you have a too many ground motion files, the script fails because it opens every time the tmpEnvelop files. It happens when we use; set Dcontent [read [open tmpEnvNodalDisp.out ]]; set Di [lindex $Dcontent 2]; puts Sd$Di set iDi "$iDi $Di"; I recommend to use the following lines: set in [open tmp...

fiber section

Hello,

I need to model a T shape wall, but it changes geometry with the heigh (the web grows). I need that the position of the flanges in the interface between two sections be the same, ie, it is necessary to have not coincident centroids.

How is it possible?

thanks!

About Fiber Section

Hello,

When I use a fiber section, is the fiber's centroid always centered with the node of the element?

Thanks!
