  • Symmetric 3D R/C buildings subjected to bi-directional input ground motion
    Faella, Giuseppe ; Kilar, Vojko ; Magliulo, Gennaro
    The influence of the orthogonal horizontal component of the input ground motion on the seismic response of a reinforced concrete building is analysed by carrying out a comparison with the response ... under unidirectional excitation. To gain reliable results, a preliminary phase of the paper is devoted to the numerical modelling of a four storey full scale r/c bare frame building tested in the ELSA laboratory at Ispra. The beams are idealised by uniaxial bending models; the columns either by multi-spring models either by two coupled uniaxial bending models in order to identify the modelling which better matches the experimental results. The numerical analysis of the seismic response of the building under bi-directional input ground motion is performed for using an ensemble of five real earthquakes. The results are analysed in terms of global and local response parameters. It is shown that the increment in damage produced by the action of the orthogonal horizontal component is particularly evident when the seismic behaviour is analysed at the local level of the member sections
