The material for the construction of the stone masonry walls will be – as much as possible – the same as the one used for a shake table test conducted at the Eucentre (Guerrini et al., 2019; Senaldi et al., 2019). The shake table test conducted at the Eucentre was also conducted at half-scale.
Material properties reported here were derived by Guerrini et al. (2017) and Senaldi et al. (2019) as part of experimental campaign conducted prior to the shake table test performed at the Eucentre. This experimental campaign comprised shear-compression tests and material tests for mortar, stones and masonry. The results of the material tests are summarised in Table 2, Table 3 and Table 4.
Additionally, participants are provided with data from cyclic shear compression test on masonry wallets of the same material and typology. The results of these tests are provided in electronic format and can be used by the participants to calibrate their models.
