GNGTS 2024 - Atti del 42° Convegno Nazionale
Session 2.2 GNGTS 2024 Fig. 1 – Drawings of the case-study historic Villa (measurements in cenCmetres). The walls are made of rubble stone masonry (mean compressive strength f c =2.17 MPa, elasCc modulus E=1500 MPa, shear modulus G=500 MPa) varying in thickness from 50 cm (ground floor) to 42 cm (upper storeys). The exisCng floors consist of Cmber joists and nailed planks, with beams oriented North-South. Structural numerical model The case-study villa was modelled in Sap2000 using a simplified but efficient approach, which was validated towards the earlier DEM modelling strategy presented in (Gubana and Melobo 2021a). To this aim, the façade shape was slightly simplified in geometry, in accordance with (Gubana and Melobo 2021a). Moreover, the roof and the 4th storey were described in terms of equivalent masses only (applied to the 3rd floor). The tympanum floor consists in a Cmber reCcular system with negligible contribuCon to the overall sCffness of the building (Gubana and Melobo 2021a).
