A pronounced isotropic hardening effect is recognized in the force deformation relationships of the TADAS devices made from two grades of low yield strength steel. The proposed plasticity fibre model employing two surfaces (a yield surface and a bounding surface) in plasticity theory accurately predicts the experimental responses of the TADAS services. This model is also implemented into a computer program DRAIN2D+ to investigate a frame response with the TADAS devices. Substructure pseudo dynamic tests and analytical studies of two storey steel frame constructed with the low yield strength steel, LYP 100 or LYP 235 grade, TADAS devices confirm that the dynamic structural response can only be predicted if the proposed plasticity fibre model is used for LYP 100 steel TADAS device.
