Abstract

This paper is an extension to the parametric elastic storey model, which includes both non-linear elastic, inelastic and hysteretic behaviour. Using a multidimensional Taylor series expansion, the linear elastic stiffness matrix for a storey is extended and developed to include parametric storey nonlinearity. This includes a quadratic hypersurface elastic storey non-linearity, which is used to model the process of deforming. A single nonlinear parameter used in defining this model is shown to be a function of reduction factor and natural frequency. A yielding criterion is defined. A hyperplane is used for undeforming resulting in hysteretic behaviour. The computational algorithm is described. Numerical results from the seismic studies are presented.
