the monastery. In the decade of French occupation, the church was used as a barn and the monastery as a military garrison. With the restoration of the 1800s, the convent was occupied by the Piarists and the Institute of Public Schools. In 1861 the structure was temporarily occupied by the National Guards of General Cosenz. In 1867, with the law of the 7 th of July 1866, which suppressed the convents and churches of some religious orders, the convent was definitively closed, while the church was used by the Piarists. In 1869, the “Domenico Cirillo” high school occupied the convent. In 1896, the “G.B. Della Porta” Technical and Nautical Institute was housed by the Convent. In 1923 a fourth and last level was added to house the “V Cuoco” high school (Maio et al. , 2016). Nowadays the building is characterised by different occupancy (Figure 5).

Figure 5. Southern Facade: different occupancy.

The ground floor houses the I.T.G. “G.B. Della Porta” and shops, the mezzanine floor Piarist fathers and residential part, the first floor the I.T.G. “G.B. Della Porta” and the I.C. “B. Croce”, the second floor the I.T.G. “G.B. Della Porta” and the third floor the L. “V. Cuoco”. In modelling, this different occupancy means different variable loads. In particular, in compliance with current Italian Building Code (NTC 18), the assumed variable loads are the following: • 2.00 kN/m 2 for the part that houses the Piarists and the residential area; • 3.00 kN/m 2 for the part occupied by the schools. 3.3. Geometrical complexities As already mentioned in the previous sections, the convent is the result of additions of different parts built in different periods. The rectangular plan is characterised by the presence of a courtyard. This typology of plan can require the analysis of the structure by considering two limit hypotheses: • no interaction between the parts: each part of the plan is modelled as an isolated structure neglecting the interaction with the other one; • perfect interaction: the building is modelled as a structural unit and assuming a good connection between the parts. 3.4. Foundations at different heights As the building is located close to the hill, the foundation of the building is at different heights. In Figure 6 the 3D view of the model of the Convent performed by using the software CDS-WIN (Computer Design of Structure s, S.T.S. S.r.l., 2021) is shown. Because of the presence of the foundation at two different heights, in the model with rigid diaphragm part of the joints of the first level are disconnected from master joint and are characterised by fixed restraints. Alternatively, the structure can be modelled by neglecting the presence of the part of structure at a lower height and considering the seismic zero at the height of the foundation of the higher level.
