SEISMIC ANALYSIS OF ECCENTRIC BUILDING STRUCTURES BYMEANS OF A REFINED ONE STOREY MODEL

摘要

A refined one-storey model has been developed which is able to evidence effects of interactionphenomena between axial and lateral forces in vertical resisting elements on torsional response of planasymmetric building structures.Previous research has shown that influence of inelastic interaction is significant, leading to larger peakductility demands and, mainly, to larger plan-disuniformity of demands in resisting elements.In this paper, the new model is used to re-evaluate, in the light of interaction phenomena, theperformances of plan asymmetric system designed according to torsional provisions of the European codeEurocode8, in order to asses its suitability regarding torsional specification.
