“…The results obtained by the shake table testing of scaled models of two historical masonry structures, namely the Old Bridge in Mostar and the ancient Protiron structure in Split, are presented in the paper of Krstevska, Nikolić, and Kustura (2020). The measured accelerations, relative and absolute displacements, and strains, as well as the damage identification during the shaking table tests, provided essential information about their seismic stability, failure mechanism, and weak points.…”

“…From this point onwards the mechanics is dominated by the rocking (DeJong and Ochsendorf, 2010;DeJong and Dimitrakopoulos, 2014;Mauro et al, 2015;Dimitrakopoulos and DeJong, 2012;Como et al, 2019;Meriggi et al, 2019) where the role of the friction becomes relevant (Monaco et al, 2014). The rocking behaviour of masonry structures can be clearly seen in experimental tests (Krstevska et al, 2020) and it represents a further, but ultimate, resource to resist severe actions (Como, 2019) even if it leads to chaotic behaviour (Mascolo, 2019).…”

Most of the computational approaches based on Heyman's theory rely on the safe theorem and can only tackle kinematical problems (KPs) with non-homogeneous boundary displacements for simple geometries. So far, no computational tools have been developed to directly address the KP for generic 2D structures taking into account different mechanical scenarios and foundation settlements simultaneously. With this aim, compas_prd, a new computational Python-based tool has been developed. It is based on the piecewise rigid displacement (PRD) method, which couples the KP with the equilibrium problem (EP), allowing the search for a mechanism and its corresponding internal stress state even in large displacements. Both KP and EP are framed as linear programming problems, allowing fast computational solving. Looking at an approximate cross-section of a multi-span masonry bridge, different mechanical scenarios are addressed to illustrate the abilities of compas_prd, also taking into account an initial deformed configuration.

“…It should be noted that there are only a few published studies focusing on the seismic behavior of buildings typical of the Adriatic coastal area. They concern experimental research about the behavior of protected buildings inside Diocletian's Palace in Split [28,29] or propose their numerical modeling using finite-discrete element models [30]. Lattice models are also being developed for the precise modeling of energy dissipation under dynamic actions [31,32] which, due to the possibility of modelling heterogeneity in materials, can be highly suitable for the numerical simulation of masonry buildings, whether of regular or irregular blocks.…”

The seismic risk assessment of existing urban areas provides important information for the process of seismic risk reduction in different phases of planning and emergency management. Between different large-scale assessment approaches, a vulnerability index method is often used for the first screening of the buildings and vulnerability classification. However, this method cannot fully predict the effects of a specific seismic action on buildings. This paper fully extends the scale of the settlement and properly upgrades a methodology previously proposed by authors to predict seismic damage and the risk to a restricted number of masonry buildings in the Croatian settlement Kaštel Kambelovac located along the Adriatic coast. The proposed approach is based on a hybrid empirical-analytical procedure that combines seismic vulnerability indices with critical peak ground accelerations for different limit states computed through a non-linear pushover analysis. The procedure’s outcomes are the computation of a relationship linking vulnerability indices to peak ground acceleration for a series of states, corresponding to damage limitation, significant damage, and near collapse. The described methodology is used to estimate seismic risk in terms of damage and the index of seismic risk for selected return periods. The general methodology has allowed a full seismic vulnerability assessment of the whole Croatian settlement of Kaštel Kambelovac.
