|Modeling the hysteretic response of mechanical connections for wood structures|
|Ricardo O. Foschi1|
ABSTRAK: Using basic material properties of the connector and the embedment characteristics of the surrounding wood medium, a general model is presented for the calculation of the hysteretic loops in mechanical connections. The approach considers the connector as an elasto-plastic beam in a nonlinear medium which only acts in compression, permitting the formation of gaps between the beam and the medium. The model automatically adapts to any input history, either for force or displacement, and develops pinching as gaps are formed. Examples are shown for different types of connections and input histories. The model can be implemented for a group of connectors, and a example is shown for the response of a connection to earthquake loading.
