“…It is worth noting that tuff infills affect strictly the first translation mode in Y direction (second mode) and the third torsional mode. Linear dynamic properties of the infilled model show a good agreement with experimental results obtained by the dynamic identification made on the building [15]. Both first and second modes in bare and infilled models show a considerable rotational participation mass coefficient (M RZ ) that slightly increases when infill stiffness contribution is considered.…”

“…Both first and second modes in bare and infilled models show a considerable rotational participation mass coefficient (M RZ ) that slightly increases when infill stiffness contribution is considered. The first three fundamental periods of the structures resulting from dynamic identification of the structure, provided by Rainieri et al [15], are linear model accurately captures periods with errors within 6%, and it shows a very accurate match for the second mode (along Y direction). …”

“…The basement is not modeled. It has a negligible interaction with the Tower, and linear dynamic behavior is slightly affected by its presence [15]. Nevertheless, the effect of the two flights of stairs is modeled restraining the degrees of freedom in plan (X, Y) at first storey.…”

Given the interest earned recently by modern heritage structures, seismic assessment criteria of Eurocode 8 for ordinary reinforced concrete structures are applied to a modern heritage RC building. The case study building, the Tower of the Nations in Naples, was designed at the end of 30's. Modal dynamic identification, in situ inspections and testing provided the necessary knowledge of the structure in terms of geometry, structural details, and material properties. Two nonlinear models of the structure are built up in both the hypotheses of accounting and not accounting for tuff infills' stiffness and strength contribution. Lumped plasticity model for reinforced concrete elements and equivalent strut models for tuff and concrete infills are employed. Seismic assessment through nonlinear dynamic analyses is carried out for both Damage Limitation and Significant Damage limit states. Assessment of bare and infilled models emphasizes a lower demand in terms of maximum interstorey drift of the infilled model with respect to the bare model, for both limit states considered. Record-to-record variability for the sets of seven records becomes larger if infills strength and stiffness contribution is taken into account. The outcome of the assessment is not affected by infills, i.e. the structure can be considered safe (according to EC8 provisions) for both limit states, and in both modeling hypotheses. On the other hand, the demand over capacity ratio, for both the limit states considered, is strictly influenced by infills' contribution. Results provided show that Eurocode assessment tools for ordinary RC structures can be addressed to modern heritage buildings, even if specific care is necessary for nonlinear structural modeling in case of non-conventional structural elements and nonconventional structural materials (e.g., tuff infills in lieu of clay hollow brick infills).

“…The ten accelerometers have been placed directly in contact with the concrete slab and parallel to the main directions of the building, in order to get both translational and torsional modes of the structure. A detailed description of OMA applied to the Tower of the Nations can be found in Ranieri and Fabbrocino (2011) and Rainieri et al (2013).

Summary Reinforced concrete (RC) frame buildings containing unreinforced masonry infill walls are commonly used in structural systems around the world. The performance of this type of building can be significantly affected by the presence of infill walls according to their type and distribution in the plane and along the height as revealed by earthquakes. This paper presents data collection, system identification, and finite element modeling of an existing RC framed building designed for gravity loads and containing unreinforced masonry infill walls. Based on a previously carried out ambient vibration test, a three‐dimensional finite element model, comprising infill walls and partitions, was successfully updated on the basis of the global modes identified by the in situ test, pointing out the important role of the nonstructural components for this type of building. The influence of the infill walls and partitions on the vibration period was examined, introducing a comparison with simple formulations for the period calculation suggested by codes or available in the literature. The updated model has been further used to assess an approach for an approximate estimation of the story and global stiffness of the building considering the effect of the secondary elements. The dynamic test with the model updating results an efficient procedure for a complete identification of the elastic behavior of the structure.
