Hi dear all, I am using the following command to record the fatigue damage: recorder Element -file $dataDir/Damage.out -time -ele 22 section 1 fiber [expr $coverSecC-$y1C] [expr $z1C-$coverSecC] $IDfatigue damage; My problem is that, while the whole frame is severely damaged after IDA, the recorded ...

Hi, I need to perform cyclic force control loading before cyclic displacement control loading. The displacement control part is OK, but I don't know how should do force control part. The forces I want to apply are a gravity load which is 100 KN and cyclic horizontal loading ( on the same node which ...

Hi,

I need to calculate distance between the bar and neutral axis ( d-x) in a RC column.

How can I calculate Depth of compression zone? Which recorders I need to use?

Thanks.

Hello,

I have used a zero length section element at the base of a RC column and need to record its Moment-Rotation behavior. I have used a section deformation and force recorder for it.

Could anybody let me know how should I use the recorded data to get M-Theta?

Thanks.

Hi, Could any one help me know what is the output format of section deformation recorder in a zero length section element? I know that in case of force beam-column element, its second and third columns are axial strain and curvature, respectively. However I do not know exactly what are the correspon...

Hi,

I want to record end rotation of a RC column. I have used a zero length section element at the base of the column.

I know that we can record Moment-Curvature directly, but I don't know how to record moment-rotation directly.

Can any one help me to sort this problem out?

Many thanks.

Hi every one,

I need to use pinching4 material to model RC beam-column joint behaviour, but the problem is that this material includes many parameters needs to be define. Could any one help me to know how should I define this parameters?

Is there any manual for it?

Many thanks,

Ebrahim

Hi dear all,

I am modelling a RC frame and I want to model RC beam-column joint using Altoontash and Lowes (2003) model with pinching 4 material.

Could any one help me? I would be very thankful if anyone could send me an example tcl code to see how should I model it.

Many thanks,

Ebrahim

Dear Mr/Mrs assimi,

If you have any experience with OpenSees on linux machines ( or if you know somebody that have been installed OpenSees on Linux), I would be thankful if you can be in touch with me.

Dear all, I extremely need to install OpenSees 2.4.6 on Linux "OpenSuse" 64 bit and run it by Matlab. Unfortunately I have not any experience with Linux. I have read other posts related to this topic but I think they are not useful for beginners. I need to step by step instructions to run ...
