seismic ductility demands of rocking structures under pulse-like ground motions

This paper provides the seismic ductility demand of rocking structures behave nonlinearity and subjected to near field pulse like ground motions. for doing this, first the interaction of nonlinear behaviour of structure and foundation uplift is evaluated using differential equations of motion, parametrically. after that, the seismic structural ductility demands are presented in forms of colourful contours as function of dimensionless parameters for a variety range of structures.
