The use of structural profiles of polymer composite materials as reinforcement of the structure of the coating or the device of emergency response from the collapse of structures
To date, in the Russian Federation there are many existing industrial facilities commissioned back in Soviet times. Many of these objects have significant dimensions in terms of, large extent and width. Gradually, the construction of the coating and overlapping in these production buildings, under the influence of environmental factors, is rendered unusable and the question of repair and reinforcement of these structures arises. With a large number of precast reinforced concrete slabs, requiring repair. In this situation, the large value of the total mass of reinforcement metal structures is a negative factor. In this regard, the advantages of composite materials are visible, whose mass is about five times less than the mass of metal structures. In this article, we will consider the possibility of using structural profiles from polymer composite materials as an alternative option for reinforcing the structure of the floor or the device for emergency response from the collapse of structures. Let's perform the calculation of standard type reinforcements for strength and maximum allowable deflections.
