Research Abstract |
A curvilinear hysteresis model is developed using load-deformation relations obtained in previous experimental studies. The new model is applicable for wide-ranged structures which have curvilinear restoring force characteristics like wooden or R/C structures. The only difference between the model parameters of wooden and R/C structure is the force level of the inflection point of the hysteresis curve. The model precisely follows the load-deformation relations shown in previous studies when the parameters are adequately determined and the loading history is not very eccentric.
