I would like to generate a fragility curve based on pushover analysis. If I can use only a single pushover analysis, is it possible to generate a fragility curve from that? How do you do it?
I want to develop one for RC Frame buildings with masonry infill.
Yang, Yes, off course.
Thanks Mr. SS, these are very helpful, especially the second one.
I have a question about a similar topic. I'm using SAP2000 to carryout pushover analysis for the purpose of fragility assessment of RC buildings. What ground motion records can I use, and how do I implement them to achieve the different damage states defined by FEMA/ATC?
I think for pushover analysis you don't need to select ground motions. For dynamic time history analysis you can select ground motion based on your associated hazard status. you can scale the any ground motion records with your design response spectra, for this you can use Seismosignal or any other relevant software. If you have no ground motion records you can use virtual records like from PEER NGA database. You can achieve different damage states from bi-linear capacity curves. see the attached paper.
Can you help me in interpretation of result for multi layer shell element
Can you please help me in development of fragility curve for shear wall which is modeled using multi layer shell element in sap 2000.
Fragility curve is just a cumulative distribution function which needs a mean and std. dev. and it depicts expected exceedance damage probabilities under a given intensity measure. If you analyse a single building, you can take that building's response as a mean representative case of that kind of building class and for std. dev. you can use Hazus Manuals where you will get convenient std. dev. suggested for different type of building in different site condition. However, these std. dev. are expert opinion based. you can follow one of paper DOI 10.1007/978-81-322-2193-7_82
