“…For example, experiments with modern materials have demonstrated that, by adding a steel tie rod, the static load‐bearing capability of a masonry arch can be increased by 300% (Ural et al . ). Furthermore, ferrous reinforcement elements also greatly increase the resistance of masonry structures to seismic loads (Lucibello et al .…”

Historical masonry buildings are often reinforced with ferrous tie rods. Before the late 18th century, such rods were hot formed by using wrought iron deriving from either the bloomery or the finery process; thereafter, the puddling process was introduced and gradually became prevalent. Several such tie rods are still in service in cultural‐heritage buildings; their analysis can shed light on historical production processes and building techniques, and knowledge of their mechanical performance can be valuable for architectural conservation purposes. Four steel tie rods, which were retrieved from a 17th century masonry building in Turin, Italy, and are dated to the late 17th and early 19th centuries, are examined here, by means of chemical and microstructural analyses, tensile tests and fractographic examinations, and both the material fabrication procedure and its mechanical performance are discussed.

“…Their popularity can be observed even nowadays. Exemplary methods of using steel tie-rods were described by Ural et al [7] and Pisani [8] while tie-rods mounted by glue were elaborated on by Matkowski [9]. The arches strengthened by using tie-rods subjected to dynamic loads, are presented in the work of Calderini et al [10].…”

The article presents a comparative numerical analysis of various ways to strengthen historical brick arches. Five ways of strengthening brick arches with steel tie-rods have been proposed. Two of these involve the use of braces wrapped around pillars supporting the arch connected with a tie-rod; the other two ways involve the use of the tie-rods with welded metal sheets of different sizes; the latter involves the use of a tie-rod glued with the use of an epoxy adhesive. The collected data were compared with the reference model of the arch left without any interference. The results make it possible to evaluate the effectiveness of the methods by comparing displacements in the vertical and horizontal direction and stresses. The article indicates the direction of proper planning and design of the arch strengthening in brick structures in historical buildings.

“…Currently, one of the fundamental problems when considering a masonry building is to implement an efficient and reliable modeling strategy that takes into account the main features of the materials in use, the mutual link between bearing walls of the structure and the layering due to building history [7], [8], [9].…”

Vol. 17, n° 2, pp. [105][106][107][108][109][110][111][112][113][114] 2018 Revista UIS Ingenierías AbstractIn this project, a historic masonry building in Sardinia, Italy has been considered as a case study for the comparison of two approaches for modeling, static and seismic analysis. Two software with different modeling approaches were employed with the purpose of comparing and discussing the results. SismiCad12 was used to simulate the structural behavior of the historic masonry building. SismiCad12 uses the Finite Element Method (FEM) that allows to model and analyze most types of 3D structures, and it is suitable for masonry structures. On the other hand, a different and innovative modeling approach called Frame Macro Elements (FME) was also applied using the 3Muri software, specially designed for assessing the linear, nonlinear, and seismic behavior of masonry structures.Assuming the same hypothesis to construct the 3D model of the structure in each code, the results of the static analysis show a different distribution of the vertical loads in the structure, which are more realistic in the FEM modeling. This different criterion of evaluation of the vertical loads carries a mechanism of "soft floor" in the pushover analysis in the FEM modeling, and therefore, a lower ultimate displacement corresponding to the collapse of the structure. On the other hand, in dynamic analyzes, FME modeling is more receptive to reality, involving a massive percentage of masses participating in the first vibration modes.Keywords: macro-elements; historic structures; pushover analysis. ResumenEn este proyecto se ha considerado como caso de estudio un edificio histórico de mampostería en Cerdeña, Italia, cuyo modelado, análisis estático y sísmico han sido desarrollados. En este estudio se han empleado dos programas informáticos con distintos enfoques de modelización con el propósito de comparar y discutir los resultados. Como primer simulador del comportamiento de la estructura en mampostería se ha elegido SismiCad12, que es una suite de Elementos Finitos (FEM, por sus siglas en inglés) que permite modelar y analizar la mayoría de los tipos de estructuras 3D y es adecuado para estructuras de mampostería. Por otro lado, se ha aplicado un método de modelado diferente e innovador denominado Frame Macro Elements (FME) con el software 3Muri, diseñado específicamente para evaluar el comportamiento lineal, no lineal y sísmico de las estructuras en mampostería.Suponiendo la misma hipótesis para construir el modelo 3D de la estructura en cada código, los resultados de los análisis estáticos muestran una diferente repartición de las cargas verticales en la estructura, las que son más realísticas en el modelado FEM. Este diferente criterio de evaluación de las cargas verticales lleva un mecanismo de "piso suave" 106M. Saba, D.
