Abstract The paper presents an application of a risk‐based methodology – developed as joint research between Politecnico di Milano and Regione Lombardia for the prioritization interventions subsequent monitoring masonry arch bridge affected by riverbed erosion. Firstly, available data on regional inventory is evaluated to assign structural hydraulic class attention. Subsequently, onsite inspect...

Abstract. The in-plane rocking of a masonry arch is studied. starting motion the assumed to take place along four-link failure mechanism u corresponding constant distribution horizontal loads proportional self-weight. During such motion, if overturning does not occur, returns undeformed configuration, with all hinges simultaneously closing. At an instant, impacts implying exchange and subsequen...

In the past, arch represented one of few structural systems which provide a possibility to cover large spans. Nowadays, same importance is presented as need increased with increase construction spans and arched structures are constructed in different shapes from various materials such brick, steel reinforced concrete. The main aim this study was investigate behavior ultimate strength concrete s...

This paper presents a new numerical tool for evaluating the vibration frequencies and mode shapes of masonry buildings in the presence of cracks. The algorithm has been implemented within the NOSA-ITACA code, which models masonry as a nonlinear elastic material with zero tensile strength. Some case studies are reported, and the differences between linear and nonlinear behaviour highlighted.

1. Abstract Topology optimization is employed to define the geometry of the cross-section of any masonry block that minimizes its thermal transmittance, with the aim of maximizing the thermal insulation of masonry buildings. Constraints on the mechanical properties of the block are also prescribed. The effect of the design constraints on the optimal layout of the blocks is investigated. The the...

• Building rehabilitation is a challenge. Old buildings must meet new requirements. Fire was responsible for many collapses in heritage (e.g. Notre Dame). A methodology to deal with fire hazards historical flooring systems presented. The validated experimental and numerical results. An exhaustive parametric study Conservation of built heritage, at present, major task great challenge because it ...

During the last decades natural polymers have become more and more frequent to replace traditional inorganic stabilizers in building materials. The purpose of this research is to establish a comparison between the most conventional building material solutions for load-bearing walls and a type of biomaterial. This comparison will focus on load-bearing walls as used in a widespread type of twenti...

The vulnerability of buildings on coastal dikes due to overtopping wave impacts is difficult to assess. A method is developed in this paper to quantify the vulnerability of masonry buildings on a coastal dike exposed to wave overtopping. Using previous studies, the accidental loads due to the extreme wave impacts are characterized. Using the approach from Eurocode 6, the strength of masonry bui...
