“…Depending on the parameters determining such processes, seismic vibrations can either amplify or, on the contrary, reduce and minimize the possible damage to the structure. Thus, in [240,241], the Preisach operator is used to model the soil-foundation interaction in the small-to-moderate ground deformation approximation. Using the harmonic balance method, the steady-state response of the system to an external harmonic excitation is determined.…”

The Preisach model is a well-known model of hysteresis in the modern nonlinear science. This paper provides an overview of works that are focusing on the study of dynamical systems from various areas (physics, economics, biology), where the Preisach model plays a key role in the formalization of hysteresis dependencies. Here we describe the input-output relations of the classical Preisach operator, its basic properties, methods of constructing the output using the demagnetization function formalism, a generalization of the classical Preisach operator for the case of vector input-output relations. Various generalizations of the model are described here in relation to systems containing ferromagnetic and ferroelectric materials. The main attention we pay to experimental works, where the Preisach model has been used for analytic description of the experimentally observed results. Also, we describe a wide range of the technical applications of the Preisach model in such fields as energy storage devices, systems under piezoelectric effect, models of systems with long-term memory. The properties of the Preisach operator in terms of reaction to stochastic external impacts are described and a generalization of the model for the case of the stochastic threshold numbers of its elementary components is given.

“…Gunaydin et al [56] assessed the structural performance of a historical masonry clock tower using both numerical and experimental processes, considering different types of SSI systems, identifying the numerical dynamic characteristics, model updating procedure, nonlinear time-history analysis, and the evaluation of seismic performance level. Cacciola et al [57] addressed the seismic response of linear behaving structures resting on compliant soil through a novel application of the Preisach model of hysteresis for nonlinear SSI problems. The method was applied to the bell tower of the Messina Cathedral in Italy.…”

Seismic Analysis of Historical Urban Walls: Application to the Volterra Case Study

2023

Several Italian cities are characterized by the presence of centuries-old historic walls, which have a cultural heritage value and, due to their structural role as a retaining wall, often influence the safety of adjacent buildings and infrastructure. Ancient urban walls are increasingly subject to instability and collapse phenomena, because the greater frequency of extreme meteoric events aggravates the static condition of the walls and of the wall–soil system. Since the seismic risk in the contexts in which the historical urban walls are located is often medium-high, it is advisable to evaluate the influence of soil moisture on the seismic response of the soil–structure system. In this paper, the seismic vulnerability of historical urban walls was examined through considering scenarios of both dry and wet soil, in order to evaluate the seismic response of the structure as a function of soil imbibition. Seismic vulnerability analyses were carried out on the case study of the historical urban masonry walls of Volterra (Italy), which have been affected by two major collapses in the last ten years. Seismic vulnerability was assessed by means of the limit equilibrium method and the finite element method, and through adopting proper soil imbibition models. The results highlight which sections of the walls are at greater seismic risk due to the presence of soil moisture, as well as the influence of soil imbibition on the structural safety and failure mechanism.

“…A wide set of analyses performed on real case studies are also included in the collection. Cacciola et al (2022) address the seismic response of linearly-behaving structures resting on compliant soil, exploring the efficiency of the Preisach hysteresis formalism to model nonlinear soil-structure interaction problems. This methodology is applied to the bell tower of the Messina Cathedral in Italy, which hosts the largest and most complex mechanical and astronomical clock in the World.…”
