FEATURES OF STRENGTHENING BUILDINGS WITH THE LATEST REINFORCING MATERIALS

Abstract

A good foundation ensures the reliability and durability of the building. In the absence of a fundamental base, the building can move, crack, and even bend, which as a result leads to uneven loads on the structure and destruction, therefore, the quality of the future structure depends on the quality of reinforcement. The use of composite reinforcement to strengthen buildings during restoration after destruction is advisable due to greater tensile strength, and also makes it easier to build due to less weight of reinforcement compared to steel. Good corrosion resistance characteristics of composite reinforcement in comparison with steel extend the life of reinforced concrete products (foundations, slabs, etc.). The type, method of connection and material of reinforcement is selected for each structure separately, and the choice depends on the type of soil, slope, size of the house, number of floors. Strengthening helps to reduce the likelihood of destruction, as well as some types of reinforcement help to eliminate irregularities and cracks on the walls during finishing work. Thanks to the correctly selected material for reinforcement, it is possible to accelerate construction. Purpose. Analyze materials for building reinforcement taking into account corrosion resistance and tensile strength. Conclusion. During the study, an analysis of reinforcing materials was carried out to strengthen the foundation and walls of buildings. Reinforcement helps to build the correct architecture of the structure and strengthen important parts to prevent destruction. It was found that reinforcement of composite materials has better characteristics than similar steel. Basic advantages: corrosion resistance and better mechanical characteristics. The design stress of the composite reinforcement under 10 kN load is 509.6 MPa which is less than the permissible − 800 MPa, and at elevated temperatures of tensile experiments the mechanical properties of the composite reinforcement change.
