This work reviews the main techniques to model dynamical systems with contact-impact
events. Regularized and non-smooth formulations are considered, wherein the fundamental …

Masonry arch bridges constitute a significant proportion of European road and rail
infrastructures. Most of them are well over 100 years old and are supporting traffic loads …

In this paper, the dynamic response of the rocking block subjected to base excitation is
revisited. The goal is to offer new closed-form solutions and original similarity laws that shed …

Predicting the rocking response of structures to ground motion is important for assessment of
existing structures, which may be vulnerable to uplift and overturning, as well as for designs …

Earthquakes represent one of the major threats to the stability of the world architectural
heritage, which is mostly constituted by unreinforced masonry (URM) structures. The …

Numerous existing structures exhibit rocking behavior during earthquakes, and there is a
continuing need to retrofit these structures to prevent collapse. In addition, while rocking …

Historical masonry arch bridges composed of foundation, arch, walls, slab and infill are very
complex structures. The dynamic characteristics of the masonry arch bridges using …

This paper aims to evaluate the limit equilibrium condition and the minimum thickness of
masonry arches in presence of horizontal loads. The analysis fits into the frame of limit …

Masonry arches are typical components of historic buildings throughout the world, and their
damage or collapse is very often caused by earthquakes. The first-order seismic assessment …

Since cross masonry vaults represent one of the more widespread types of horizontal
structural elements in historical constructions, understanding their behaviour is a crucial …
