Calculator

How to Use

In ETABS / SAP2000, the Tectonus device can be modeled using the “Damper – Friction Spring” link Element. This function accurately represents the flag-shaped hysteresis of a Tectonus device provided its parameters conform with the design parameters of the joint. The parameters can be generated automatically using the calculator below. Input your values on the left and check the results generated on the right.
