Hi everyone, could you tell me how to calculate beta1, beta2, yield strain1, yield strain2 and ultimate strain in Takeda hysteresis model.....
This is a good question.
To get started, consider
M. Bimschas, Displacement based seismic assessment of existing bridges in regions of moderate seismicity, Ph.D. thesis, TU Darmstadt, 2010:
http://e-collection.library.ethz.ch/eserv/eth:1193/eth-1193-02.pdf
Using regression analysis, Priestley et al. calibrated an individual set of parameters for four different hysteresis models, including Takeda fat hysteresis and Takeda thin hysteresis (see Secttion 4.5, starting on page 195).
See, also, E. Smyrou, J.J. Nigel Priestley, A.J. Carr, Modelling of elestic damping in nonlinear time history of cantilever RC walls, Bull. Earthquake Eng, 2011, here on RG:

See See Section 2.5, especially equations (4) and (5) in computing hysteric damping. This is a very detailed account.
See, also, the hysteric model for infill panels in
A. Shooshtari, Seismic Drift Demands of Reinforced Concrete Buildings, Ph.D. thesis, Carlton University, Ottawa, Canada, 1998:

Thank you so much, Prof. James F Peters, for your answers. I do appreciate for these...
