RC joints

[newman]

Could you please let me to know that how can create a suitable model for RC joint? I know that it needs link elements and also elfrm elements, but, how should be define the behavior curves parameters for these link elements when there are no test for calibration? I want to know that the researchers how create a RC joint in seismosoft without any test data while it needs to define a lot of parameters values for behavior curves (such as Takeda). Please clear to me what is the best method to create a simple RC joint model in seismostruct. I read the verification reports and also read its details, but it was adjusts and calibrate based on real test data which is not used in other RC joints. I also search for that in other papers and dissertations, but, a lot of them, used other softwares. I create my frames in seismostruct, but from three month ago, I'v been working for modeling a simple reliable RC joint, but I didn't success. I really needs help for that. Please guide me. Thank you.

In general, the modelling requirements should be the same in all similar FE packages, hence if you read all the reports and papers published on the subject you should get a good idea on how to carry out your modelling. Further, in particular for SeismoStruct you can as guide the files fom the RC joint models that we use in our verification report. However, note that in general in large structures RC joints are typically modelled as rigid offsets (the best way for you to understand this is to create a simple model with the Building Modeller). Finally, ASCE 41-13 provided good insight on the issue in Chapter 10.
