“…Better ductility may be caused by the greater density of steel textile. Garmendia's comparative research [84] shows very similar deformability of SRG-and SRP-strengthened arches. The same UHTS steel tape was used in these tests.…”

Bonding of external reinforcement is currently the simplest, fastest, and most popular method of strengthening concrete and masonry structures. Glass and carbon organic fibers are the dominant materials used, but alternatives also include high-strength steel wires. The mechanical properties of such steel are comparable to those of carbon fiber. Due to their good compatibility with mortars, steel wires are particularly well suited to the revitalization of historic buildings. The manuscript provides an overview of research and experience in the use of steel-reinforced polymers (SRPs) and steel-reinforced composite mortars (SRCMs, also called steel-reinforced grout (SRG)) for structural strengthening. The examples described are for concrete beams, slabs and columns, walls, and masonry arches. The results of laboratory tests are discussed. The summary presents the advantages and disadvantages of composites based on ultra-high-strength steels compared with more popular carbon fiber composites.

Application of lime-based textile-reinforced mortars (TRMs) for strengthening of masonry structures have received a growing attention in recent years. An extensive effort has been devoted to understanding of the performance of these composites and their effectiveness in improving the seismic safety of existing masonry structures. Nevertheless, several aspects regarding the durability and mechanics of these composites still remain unknown. This letter is an effort on highlighting those aspects considering both experimental and numerical modelling approaches.

“…Though the polymer-reinforces fibers are the most commonly used to strengthen vaults and arches, they still possess the disadvantages of lack of water vapor permeability [62] proposed an alternative method by embedding long steel fibers and basalt textiles in the mortar to provide a steel-basalt reinforce mortar-based composite. The retrofitting results are compared with the polymer composites and both cases are effective in strengthening masonry vaults in terms of increasing of load and deformation capacity [6] agrees with the work of [62] that basalt on a mortar matrix provides both higher capacity and better ductility compared with polymer matrix.…”

Masonry structures commonly exist in reality and still are popular all over the world. It has been reported and studied that these buildings are vulnerable to strong external loadings imposed by earthquake, strong wind, blast etc. In the past few decades, different seismic retrofitting and strengthening approaches for masonry structures/elements have been developed and implemented. In this paper, the previous studies on the strengthening/retrofitting techniques for Unreinforced Masonry (URM) buildings subjected to seismic and extreme loads are reviewed and summarized. The fundamental concept of strengthening/retrofitting approaches is to (i) reduce the influence of external loading, (ii) upgrade the individual element's load-carrying capacity and (iii) improve the integrity of masonry structure. A comparison and assessment of the advantages and disadvantages of each method is presented to identify the most suitable method in different cases. It is expected that this paper will provide some helpful information and guidance for the engineers and householders in choosing an appropriate technique in strengthening/retrofitting URM structures.
