“…Within this framework, different new building typologies were considered, including reinforced concrete (r.c.) buildings (Ricci et al 2018, steel buildings (Scozzese et al 2018), precast structures (Magliulo et al 2018), seismically isolated buildings (Ragni et al 2018) and unreinforced masonry (URM) buildings. The latter is still the most commonly adopted solution for structural masonry in Italy, although reinforced masonry is also an option.…”

Various architectural configurations of URM residential buildings are designed according to the different methods the Italian code: rules for the so-called simple masonry buildings, linear and nonlinear static analyses. Always complying with code requirements, for each building-site combination the design was made, as much as possible, without an excessive margin of safety. The different design methods provided buildings with very different levels of safety, being linear static analysis largely overconservative with respect to the nonlinear static approach. These buildings were then analyzed in the companion paper by Cattari et al. (2018).

“…time history analyses, are performed for ten different intensity motion (IM), with increasing intensity, from PGA equal to 0.011 g to 1.077 g. Each IM has twenty records in both horizontal directions and it corresponds to a defined return pe-riod Tr (Table 1). The records were selected according to the conditional mean spectrum approach [48]. The value of the reference period was selected to be appropriate for the fundamental period of the considered structure (2.0 s).…”

The present research is aimed at evaluating the influence of different modelling assumptions, such as crane-load and beam-column connections, on the local seismic response of precast RC buildings. The considered case study is a one-story industrial building designed in accordance with the Italian building code NTC 2008. Typical pinned beam-column connections are investigated. They are made by dowels protruding from the column inserted into holes in the beams, which are subsequently grouted. This technique ensures stability during the construction process and allows the horizontal seismic load transfer from the beam to the column. Different structural layouts have been modeled considering various types of beamcolumn joint models, namely a perfect hinge, an elastic hinge and a non-linear spring with a degrading hysteretic force-displacement model; the last model reproduces the results of recent experimental campaigns. Non-linear dynamic time history analyses allow to evaluate displacements, drifts, deformations and ultimate curvatures. The results are analyzed in terms of both global quantities, i.e. roof maximum displacements and rotation at the base of the columns, and local quantities, i.e. force or displacement demand at the beam-column connections, for the various implemented models. Depending on the considered model, it is observed that the effects of higher vibrating modes may increase the load in the connections.

“…Starting from the work of Bressanelli et al (2019) and Magliulo et al (2018), this research moves further by: investigating two different hysteretic models for the beam-to-column connections, such as the hysteretic uniaxial material model (Sousa et al, 2020) and the Modified Ibarra-Medina-Krawinkler Deterioration model (Lignos and Krawinkler, 2011); explicitly modelling the cladding panels in a pendulum configuration; removing the hypothesis of rigid diaphragm by introducing the roof elements and three types of beam-to-roof connections, namely hot-rolled, cold-formed and welded; explicitly modelling the overhead crane and the oscillating payload. The building collapse rates obtained from the comprehensive 3D model allowed to validate the collapse rates obtained from previous simplified analyses.…”

This research evaluates the influence of different modelling assumptions on the global and local seismic risk assessment of code-conforming precast reinforced concrete buildings, specifically single-story industrial buildings. In particular the modelling of the system mass, the overhead crane, the beam-to-column and roof-to-beam connections and the cladding system are investigated. For this purpose, a case study resembling a new industrial building designed in accordance with the current Italian building code was selected. Typical dowel beam-to-column connections were considered and the influence of various modelling strategies investigated: perfect hinges, linear elastic connections and non-linear connections with a degrading hysteretic force-displacement model which was calibrated from available data on experimental tests. Three different types of roof-to-beam connections were investigated removing the assumption of rigid diaphragm, namely hot-rolled, cold-formed and socket welded connections. Initially, simplified planar models of single frames were considered to evaluate the influence of the different modelling strategies, then 3D models of the entire building were analyzed. Multiple-stripe non-linear dynamic time history analyses allowed to evaluate displacements, drifts, deformations and ultimate curvatures of the main elements and connections for various intensity measure levels. The seismic risk was assessed in terms of failure rate considering the collapse of both the columns and of the connections. The results show that the beam-to-column connections fail right after reaching yielding due to their low displacement ductility, leading to the loss of support of the beam and therefore increasing the collapse rate of the investigated structural typology.
