Abstract. This study presents an original inelastic beam-like model for the simulation of the nonlinear dynamic behaviour of three-dimensional buildings subjected to earthquake loadings. The proposed model is defined as a step-wise shear only cantilever beam, whose segments have the same mechanical properties of the corresponding inter-storeys of the building. The inter-storey constitutive laws are calibrated by means of the results of a static nonlinear analysis performed on the 3D FEM model of the building. An inverse nonlinear static identification procedure allows obtaining an inelastic beam-like model equivalent to the more demanding 3D FEM model, related to a specific direction and under a precise distribution of horizontal loadings. Dynamic nonlinear analyses performed on this simplified model allow a drastic reduction of the required computational effort and time with respect to the more demanding 3D FEM model. The reliability of the proposed beam-like model is validated through numerical applications on an irregular multi-storey RC frame representative of residential buildings in Catania designed to resist only gravity loadings.
