Re: Fragility Analysis

Respected Sir,

I've mailed you my code samples and other relevant details.

Thankyou.

Re: Fragility Analysis

Hi Professor Scott,

As I told you earlier, I've tried out some basic examples from OpenSees Documentation.

As I've to generate fragility curves using passive vibration control devices, I will have to define my material and the parameters.
uniaxialMaterial $someMaterial $matID $Cd $a ($Cd=Damping Co-efficient , $a = Damping exponent)

The steel frame would be coded as I saw in examples, by :
1. Defining Geometry
2. Defining Nodes.
3. Defining the single point constraints
4. Setting up mass
5. Setting up column and beam properties.

After, this when my frame is ready along with the damper, (I'll also have to connect the damper between two nodes), my setup will be complete.
After this, I'm completely unaware on how to generate the fragility curves. You'd told me about the Fragility module being deprecated, I'll have to use FORM analysis. Could you please help me a bit? I'm new and not able to find proper documentation/examples on using the FORM analysis.

Thanks.

Re: Fragility Analysis

Thanks for the quick response.

I'm quite new to OpenSees currently. I'm still learning and have just tried out simple programs to generate frames.

My project concentrates on generating fragility curves for building frames with passive dampers for seismic analysis. Hence, I was wondering if I will have to code my own fragility function or is there something already in OpenSees that I could make use of. This is all I can tell you currently. But, within a fortnight, I would definitely, come up with a script and post it as you've suggested.

If I'll have to make my own fragility function, using loops etc. as you suggested, what is the use of FragilityApnalysis C++ file in APIs?

Fragility Analysis

How could I use the FragilityAnalysis.cpp file in OpenSees API to generate fragility curves?

Are there any examples portraying the use of API and how to use APIs?
