Hi ! I have some quereis regardinh nonlinear analysis. I am going to perform Nonlinear Dynamic Analysis using SAP2000. First of all, tell me what is the difference between simple stress strain curve and Hysteresis model. If i have the compressive tested concrete and its stress strain data from UTM then i will define the curve as it is in SAP2000. So why Hystereis is required.As in SAP2000 variois Hystersis models are available i.e. Takeda, Concrete etc..What is the purpose of these models ? So if i don't want to use builtin Hysteresis model, can i define my own model? If yes then from where i will find this model? Is it from shake table test ? Further, at where i will define that hysteresis data in SAP2000 as i have already defined my stress strain curve of concerte which was obtained from Universal Testing machine ? May these Hysteresis models run the defined stress strain curve ? Anybody can clear my points ? Thanks
