Target Displacement Parameters (KANEPE)

Herein the structural type of the building is specified for the proper definition of the C2 factor, taken into consideration in the Target Displacement calculations of KANEPE. It is noted that the C2 factor takes into account the influence of the shape of the hysteresis loop at the maximum displacement.

As structural systems of Type 1 are denoted structures with low ductility (e.g. buildings constructed prior to 1985 or buildings whose capacity curve is characterized by an available displacement ductility which is lower than 2), that are expected to have inferior hysteretic behaviour than structures with high ductility which are characterised as Type 2 systems, e.g. buildings constructed after 1985, or buildings whose capacity curve is characterized by an available displacement ductility which is higher than 2. Given the fact that the influence of hysteretic behaviour is greater for higher levels of post-elastic structural response, the values of the coefficient C2 are conditioned to the performance level.
