Zaccone, L, Stendardo"^^xsd:string ; pubblicazioni:descrizioneSinteticaDelProdotto "Historical masonry structures constitute an extremely varied and complex set as far as typologies and building techniques. The analyses of their structural behaviour, when excited by a seismic event, are often affected by considerable uncertainty arising from the hypothetic definition of the mechanical properties of materials and of constraint conditions between the elements.\nThe mechanical modelling of a historic building requires a knowledge of the properties of the various elements that make up the masonry and of the role they play: the masonry material, its use in the various components and, finally, how the connection between different elements are made in order to construct the building.\nThe results of the work of modelling and the results of static and dynamic (seismic) analysis of the Temple of Athena, part of the broader site of monumental historical buildings in the Plain of Paestum, are presented in this paper.\nThis work is part of the research project \\\"Costruito\\\", carried out within the Istituto di Cibernetica \u0091E. Caianiello\u0092 in Naples, which has, among its objectives, the purpose to define the main phases of the procedure that, starting from the identification of a historical building, ends with the determination of its structural behaviour in static and seismic phases.\nThe entire structure of the Temple of Athena has been modelled through a micro-modelling strategy in order to reproduce as faithfully as possible the whole geometry of the building. This approach has the disadvantage of being computationally expensive, given the large number of finite element to be generated, but at the same time the merit of allowing, at a later stage, a more thorough validation and verification.\nTo face the high computational cost, particular attention was paid to the continuous verification in the modelling phase, through accurate test quality of the meshed finite elements. The control of the characteristic length of each element has allowed to establish a lower limit to the size of time step and to contain within certain limits the duration of simulations.\nWith respect to this objective it has proved successful the choice of the modelling and pre-processing software, Hypermesh, that provides advanced features regarding the meshing procedure together with plenty of effective testing tools.\nThe solver adopted for the simulation phase is Radioss, whose characteristics are well fit for the modelling of the contacts between surfaces (penalty methods based contact). A parallel version of this software (4-CPUs) was used for the simulation on a vectorial / parallel machine NEC Sx-8.\nThe results of simulation tests regarding static and seismic analysis are finally presented."^^xsd:string ; pubblicazioni:affiliazioni "Istituto di Cibernetica\nCIBEC, Universit\u00E0 Federico II di Napoli"^^xsd:string ; pubblicazioni:titolo "High performance computing applied to seismic FEM analysis of historical heritage.
