Abstract
Strengthening of reinforced concrete girderless floor with a broken protective layer of concrete with composite materials
Incoming article date: 23.10.2022The trends of modern society require a quick solution to the issues of restoration of emergency buildings and structures. New methods of strengthening the load-bearing structures of buildings are aimed at reducing labor costs, the timing of work and the need for complex equipment. In the field of reinforcement of reinforced concrete structures, such methods are composite reinforcement systems. Having proven itself well in working with bendable and compressed elements, there are areas where their use has not yet been studied. One of these is the reinforcement of reinforced concrete girderless floors, in which the protective layer of concrete is broken. This article is devoted to the development of a method of reinforcement with composite materials, where the protective layer of concrete was violated. At the same time, the internal moment of a pair of forces reduces the bearing capacity of the element by about 30%. The paper presents the advantages of the new composite reinforcement method and provides a possible example of its use on a real object.
