Microbial-induced calcium carbonate precipitation (MICP) is a novel approach that already being applied in various areas of construction. The precipitated can be used to reduce porosity and thus increase the durability deteriorated building components. This study investigates whether MICP injections are suitable for rehabilitation. Porous mortar test samples recycled aggregate parts masonry wer...

This paper presents an accurate and efficient computational strategy for the simulation of coupled masonry structures which combines a partitioned mesoscale modelling approach for brick-masonry components with a mortar mesh tying method for non-conforming interfaces. This allows the independent modelling of the individual structural components and the efficient tying of the subdomains with accu...

Virtually all masonry arch bridges contain masonry parapets and, because of the possibility that these may be extensively damaged following a vehicle impact, it is often reported that these give engineers more cause for concern than the arch barrel itself. Over the past decade research has been carried out to gain an understanding of the fundamental modes of resistance of unreinforced masonry p...

Moisture diffusion and carbonation influence the behavior of multiple-leaf ancient masonry walls, producing during centuries a redistribution of stresses from the core of lime mortar concrete to the external cladding of stiff masonry. This is likely one of the causes of long-time damage of some ancient masonry towers. With these motivations, coupled processes of moisture diffusion, carbon dioxi...

Static-cyclic shear load tests and tensile tests on retrofitted masonry walls were conducted at UAS Fribourg for an evaluation of the newly developed retrofitting system, the S&P ARMO-System. This retrofitting system consists of a composite of carbon mesh embedded in a specially adapted high quality spray mortar. It can be applied with established construction techniques using traditional const...

Abstract UnReinforced Masonry (URM) buildings constitute the majority of Italian building stock and represent one most vulnerable construction typologies, as emerged during seismic events occurred in last decades. The objective present work is proposal a methodology for vulnerability fragility assessment different typologies URM buildings. Through statistical analysis post-earthquake damage sur...

In addition to reinforced concrete and steel buildings, a large part of the existing building stock in Europe is made stone masonry. Prediction structural behavior requires development systematic material characterization mechanical properties details (units, arrangement, bonding, inter-connection). This study aims analyze physical stones historical city Gjirokastër, Albania, known also as Ston...

The present paper makes a critical review of some methods and models, now available in the technical literature and commonly used in the analysis of masonry vaults up to their collapse, by highlighting advantages and drawbacks of each approach. All methods adopted to describe the mechanical behavior of masonry structures, in order to be reliable, must take into account the distinctive aspects o...

This article contains information related to a recent study "Performance-based interpretation of in-plane cyclic tests on RC frames with strong masonry infills" (Morandi et al., 2017 [1]). Motivated by the necessity to improve the knowledge of the in-plane seismic response of rigid strong masonry infills, a wide experimental campaign based on in-plane cyclic tests on full-scale RC infilled fram...

High, sustained loads in masonry cause time-dependent deformations, which can lead to failure of the construction. This phenomenon mostly occurs in high constructions, such as historical towers, where the dead load imposes significant stresses on the base of the tower [4]. As knowledge and experimental data are lacking to describe this time-dependent behavior in historical masonry, a research p...
