Shock Covid and Italian Private Healthcare: Some Assessments of Economic and Financial Performance

Aim: to focus on the trend of employment, profitability, and capital structure of a sample of 2,318 Italian private healthcare companies over the period 2013-2022 to test the following hypotheses: (H1) the pandemic increased employment; (H2) the virus increased profitability; (H3) the increase in healthcare demand improved the capital structure; (H4) there are no significant differences between the different macro-regions of the country. Methodology: analysis of financial statements and calcu...

Seismic assessment and upgrading of existing non-conforming multi-storey steel buildings: A case study

While dealing with existing steel constructions, an high level of variability is encountered with reference to structural conception and typology of load-carrying systems. Furthermore, such structures often prove to be non-compliant with current codes, thus showing crucial structural shortages in many cases. Within this framework, an existing non-conforming six-storey steel building is in this article as a case study. The selected construction features both Moment Resisting Frames (MRFs) and ...

Seismic Assessment and Strengthening of an Existing Industrial Building

Nowadays, the development of rapid and low-impact structural rehabilitation strategies and techniques is very topical. These prerogatives are essential for the seismic retrofit of industrial buildings, for which the seismic retrofit solution should be selected also accounting for the impact of the interventions on the productive activities. Therefore, a retrofit solution that allows to increase the structural capacity without interfering with the industries production could be preferred with ...

Seismic Behaviour of Steel MRFs Designed According to EN1998-1(2005) and prEN1998-1-2(2020)

This study aims at evaluating the capacity of steel moment frame (MRF) structures at collapse limit state designed according to the current version and next release of Eurocode 8. To this purpose, the framework of performance-based earthquake engineering according to PEER is adopted. The collapse intensity and subsequently the mean annual rate of collapse are computed as an index of comparison. The structural assessment is carried out by means of nonlinear static and dynamic analyses on 2D mo...

Preliminary Results from Shake Table Tests of the FUTURE Mock-Up

The EC8 design rules and requirements for steel moment-resisting frames (MRFs) mainly address far-field seismic scenarios. However, there are specific issues to account for Near Fault (NF) strong motions that may increase inelastic demand on structural steel members and joints. The latter are usually designed or qualified for far-field earthquakes. Also, the drift displacement is often characterized by severe unidirectional concentration. Another aspect influencing the design of MRFs is the l...
