Special Issue Information

Dear Colleagues,

The reinforcement of historic masonry constructions is often the cause of disproportioned damages during earthquakes. This fact, which is illustrated by many recent seismic events, is mainly due to a lack of knowledge in the engineering standards and techniques of the past time. This knowledge gap is reflected in our numerical models and day-by-day professional practice. Commonly, methodologies that are appropriate for modern building techniques are implemented by ignoring the basic evidence that masonry has stood the test of time, even in seismic-prone areas. These warnings, which are amongst many, have often been left unheard and forgotten. Because of this, this Special Issue aims to collect contributions investigating the appropriateness and effectiveness of existing as well as innovative retrofitting techniques. It is worth noting that in the case of an existing masonry, due to its variability in materials and construction techniques, no general repair method exists, but only methods fitting the specific masonry characteristics. For this reason, once a repair technique is proposed, it should be experimentally and numerically studied to understand not only the best application procedure, but also its effectiveness. State-of-the-art review articles explaining the work of last few decades are also welcomed. Thus, researchers, engineers, designers, and material experts working in the civil engineering field can share their latest contributions.

Abstract
One way to improve a structure’s total load-bearing capacity during an earthquake is to apply fiber-reinforced polymers (FRP) to unreinforced walls. The study discusses the use of FRP to strengthen unreinforced masonry (URM) structures. Although, many studies were conducted on the FRP strengthening [...] Read more.
One way to improve a structure’s total load-bearing capacity during an earthquake is to apply fiber-reinforced polymers (FRP) to unreinforced walls. The study discusses the use of FRP to strengthen unreinforced masonry (URM) structures. Although, many studies were conducted on the FRP strengthening of URM buildings, most of them were experiments to investigate the success of retrofitting approaches, rather than developing a successful design model. A database of 120 FRP-reinforced wall samples was created based on the current literature. Various approaches for calculating the bearing capacity of FRP-reinforced masonry are presented and detailed. The findings of the experiments, which were compiled into a database, were compared to those derived using formulas from the literature and/or building codes, and the model’s limitations are discussed.

Masonry towers, located in seismic zones, are vulnerable and prone to damages up to compromise their stability. The scatter of data on the mechanical properties of masonry, geometry and boundary conditions determine a lack of building knowledge on their expected behaviour. Therefore the assessment of the seismic capacity represents a critical task. This paper contributes to the issue of seismic analysis of masonry towers, focusing a meaningful case study: the St.Silvestro belfry in L’Aquila, Italy. The tower, severely damaged by the 2009 earthquake sequence, underwent extensive restoration works, endeavoured to mitigate its vulnerability. The observed seismic damage, the performed no-destructive testing campaign and the accomplished rehabilitation measures are described in the paper. The authors appraised the actual seismic performances of the St.Silvestro belfry, reinforced by the last restoration works. At first, the Operational Modal Analysis (OMA) is carried out to enhance building knowledge. In a second step, a refined finite element model is calibrated on the results from OMA to seize the actual dynamic response. Ultimately, by using the updated finite element model, the authors estimate the fragility curves in terms of peak ground acceleration using truncated incremental dynamic analyses. Full article
