“…For an assigned class of vulnerability, they express the probability of exceeding a certain level of damage as the hazard measurement parameter varies, which may be the peak seismic acceleration, spectral intensity, macroseismic intensity, etc. [28][29][30].…”

Italy is a country with high seismic hazard, however since the delay in the seismic classification of the national territory, most of the existing building heritage does not comply with the current technical standards for buildings. The seismic events that have hit different Italian regions in recent years have highlighted the complexity of the challenge for the public bodies both in the emergency management and post-event reconstruction and in the planning of effective risk prevention and mitigation measures to be implemented in ‘peacetime’. These difficulties concern, in particular, the capacity to properly manage the financial and technical resources available and to identify the intervention priorities throughout the entire emergency cycle. For correct management, the priority is to quantify and localize, through simulations, the quantification of probable damages and to evaluate in terms of cost-benefits the possible alternative strategies for mitigation, also taking into account the potential, in terms of cost-effectiveness, of integrated measures for seismic and energy retrofitting. In this framework, the project CAESAR II (Complementary Analyses for Emergency planning based on Seismic Risks impact evaluations) has been developed as a Decision Support System for Public Authorities in charge of developing Disaster Risk Reduction plans, with the possibility of programming mid to long-term investments for public and private properties, as well as defining custom financial support mechanisms and tax incentives.

“…In these types of buildings, it is common that torsion will be predominantly resisted by the possibly many existing RC walls. In some low-to-moderate seismic regions, it is common to find a single, peripheral core wall, which alone needs to resist both the lateral and torsional actions of the building (Hoult et al, 2015). In this situation, it is possible that the additional stresses induced in the wall from the combination of axial, bending, shear, and torsional actions results in a premature and brittle failure.…”

“…For example, to increase the net lettable area of a building, the reinforced concrete (RC) core wall(s), which provide the lateral resistance to seismic and wind loads, are often designed and constructed on the periphery of the structure. This building typology is common in low-to-moderate seismic regions, such as Eastern North America, Australia, and Hong Kong (Hoult et al, 2015; Pelletier and Léger, 2017; Peng and Wong, 2008) and are susceptible to non-negligible torsional demands when subjected to earthquake ground motions. In these types of buildings, it is common that torsion will be predominantly resisted by the possibly many existing RC walls.…”

This data paper describes an experimental campaign on two reinforced concrete (RC) U-shaped walls, including details of the test units, materials, test setup, loading protocol, instrumentation, primary observations and response of each unit during testing, organization of the test data in the public open source research data repository (DOI: 10.14428/DVN/FDJ4EU), and examples of derived data. The two wall units represent the lower stories of a half-scale 6-story prototype core wall that was designed for medium-to-high ductility. The tests conducted aimed at assessing the flexural and torsional response and capacity of RC U-shaped walls. The first wall unit, UW1, was tested for axial-flexure and subjected to quasi-static reverse-cyclic bending about its weak axis until failure. Furthermore, UW1 was subjected to an additional overturning moment to increase the shear span. The second wall unit, UW2, was tested for axial-torsion and subjected to a quasi-static reverse-cyclic rotation about its vertical axis until failure. Both wall units were subjected to a constant axial load ratio of 5%. A range of conventional instrumentation was used to capture salient global and local measurements of the wall, including three-dimensional (3D) digital image correlation on multiple faces. High-definition fiber-optic sensors were also utilized to capture the entire strain profile of several longitudinal reinforcing bars in each wall unit.
