Abstract
The article presents the most innovative methods of strengthening and (or) seismic strengthening of masonry for use in historical buildings that are of architectural value, for example, in old mosques in Syria, which are architectural monuments. These methods are designed to protect such buildings, many of which are of architectural and cultural value and are on the UNESCO World Heritage List, from cracks of various sizes and directions and from the negative effects of earthquakes that can occur at any time. Carbon fiber reinforced polymer rods (CFRP) rods and stainless steel helical rods are considered. Two mosques in Syria are briefly described as examples of historical masonry buildings, which are architectural monuments and objects of cultural heritage. In the end conclusions are drawn.
Highlights
Existing historical buildings, built of masonry, some of which are architectural monuments, are located in different countries for example Russia, Italy, Greece, Spain, and Syria [1,2,3,4]
It is worth noting that similar buildings and structures are common all over the world, the approaches to strengthening given in this article are suitable for use everywhere in them
One of the innovative traditional methods of strengthening and seismic strengthening of buildings and structures is carbon fiber reinforced plastics (CFRP), which are polymer composite reinforced with carbon fiber materials, and are known as an alternative to the traditional steel rods for reinforcement of masonry and other building structures
Summary
Built of masonry, some of which are architectural monuments, are located in different countries for example Russia, Italy, Greece, Spain, and Syria [1,2,3,4]. It is worth noting that similar buildings and structures are common all over the world, the approaches to strengthening given in this article are suitable for use everywhere in them These historical buildings and structures were usually built of unreinforced masonry, so they are vulnerable to earthquakes and other natural and unnatural disasters [5,6,7]. Buildings with unreinforced stone walls are structures characterized by inadequate earthquake [8,9] behavior due to their low ductility and low energy dissipation capacity These structures are very vulnerable to this kind of natural phenomena and can face sudden failures that can even lead to their complete destruction. This was observed during previous earthquakes, such as the earthquakes in Tashkent, in the USSR with a magnitude of 5.2, in 1966; in Los Angeles, USA, in 1994 with a magnitude of 6.7; in Mexico, in 2003 with a magnitude of 7.6; in Chile in 2010 with a magnitude of 8.8 and others
