“…In particular, values equal to 1.6 and 0.7 were assumed for kr and k0 in case of masonry piers (k0 = 0.5 for spandrels); such assumptions are compatible with the experimental evidences from Morandi et al (2016Morandi et al ( , 2018, in the case of piers, and from Beyer and Dazio (2012), in the case of spandrels.…”

The URM buildings designed to be conforming with the Italian building code, as illustrated in the companion paper by Manzini et al. (2018), were analyzed by performing time-history analyses on models realized using an equivalent frame approach and by adopting two different constitutive laws. Both the effect of record-to-record variability and of epistemic and aleatory uncertainties in modelling were explored. The achieved results constitute the basis for the evaluation of the risk level implicit in Italian code-conforming buildings (Iervolino et al. 2018). Two main performance conditions are considered, namely usability-preventing damage and global collapse limit states.

“…In general, the adoption of other masonry typologies (e.g. aerated autoclaved concrete or lightweight aggregate concrete blocks), all complying with code requirements, would not affect the "design" phase, although some differences in the risk assessment phase may result from a possibly different in-plane drift capacity of masonry piers (Salmanpour et al 2013, Petry and Beyer 2014, Snoj and Dolšek 2017, Morandi et al 2018.…”

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).

The material and structural performance of calcium silicate (CS) brick masonry has received relatively little attention in the past, although this material is often used for the construction of low-rise buildings in Central and Northern Europe. Upon the occurrence of induced seismicity in the north of the Netherlands, an extensive testing programme has been conducted since 2014 at Delft University of Technology. The paper presents the outcomes of eight quasi-static cyclic tests performed within this program on CS brick masonry walls under vertical and lateral in-plane loads. Different dimensions, boundary conditions and applied pre-compression loads were considered. Overall, the tests allowed to characterise the in-plane behaviour of CS brick masonry walls. The results confirmed the influence of the shear ratio (i.e. the ratio between the effective height and the length of the wall) on the wall response in terms of prevailing failure mode, initial stiffness, force and deformation capacity, energy dissipation. Besides, the experimental outcomes stressed the difficulty in estimating the effective stiffness and near collapse drift capacity. Additionally, an empirical equation is proposed to predict the peak lateral force. The equation, calibrated against the tests presented in this paper, was validated against an extended dataset of tests performed on CS masonry walls. The equation, which does not need any input of material parameters and is applicable irrespectively of the expected failure mode, can be used to estimate the force capacity of CS masonry walls when no or limited data on the material properties are available.
