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.

The building heritage of many seismic regions worldwide is largely substandard and seismically deficient and would require seismic retrofitting interventions. The use of natural materials with low embedded emissions could lead to a low carbon footprint of the retrofitting intervention. In this perspective, an innovative structural sustainable retrofitting system is proposed consisting of a hybrid steel–bamboo reticular bracing system. Through a preliminary two-dimensional analysis, the capabilities of the system are assessed by varying the size and the number of the culms and inserting engineered bamboo and steel rods. Considering the constraints posed by the openings, a structure that uses steel in the first inter-storey and bamboo in the others is proposed to obtain a significative improvement of mechanical performances. The spatial behaviour of this structure is studied through a three-dimensional numerical model. The seismic analyses show that the exoskeleton structure when conveniently anchored allows to achieve an effective displacement and deformation control on the primary structure, as well as a reduction of its internal forces. The results of the presented work may provide useful preliminary insights. Further research effort is needed to generalize the results to different seismic zones. The proposed seismic retrofitting system could be easily integrated with a thermal coat to also enhance energy saving.

“…The existing methods of retrofitting unreinforced masonry buildings such as surface treatment [1], post-tensioning [2], steel cage mesh retrofitting [3], polymer mesh retrofitting [4], plastic carrier bag mesh retrofitting [5], PP-bands mesh retrofitting [6], bamboo band mesh retrofitting [7]; use of strengthening materials on masonry structures improves its lateral strength. However, some referred strengthening materials are beyond the economic ability of the common people of the developing countries.…”

Among the world population, a large proportion across the world still lives in masonry structures. The main problem in unreinforced masonry structures is its weakness against dynamic loads. This paper presents the proposal of the new retrofitting method using natural fiber added mortar as the surface plaster for masonry structures. Thus, the present study focuses on the experimental evaluation of a masonry prism with natural fiber reinforced mortar. The main reasons for the use of coconut coir as a natural fiber are richly available in locally and are fairly cheap. In this paper, the effects of coconut coir reinforced mortar mix, including different fiber content on compressive, shear and flexural bending behavior of masonry prisms is investigated through a comprehensive experimental study. Although this technique shows an average performance, due to the facts of low cost, local availability and relative simplicity of technique, this method may potentially be able to use to prevent the brittle collapse of unreinforced masonry structures under moderate seismic loading.
