STRENGHENING OF RC BEAMS BY FRC AND FRP SYSTEMS – A REVIEW

The article examines studies on the reinforcement of reinforced concrete elements of cement -based fibro -based fibro systems (FRC) and polymers reinforcement fibro (FRP). Nowadays, the world economy, and with it, the construction industry is developing at a rapid pace. New materials, mechanization, construction equipment are emerging on the market. Due to this, modern structures impress with their shapes, scale and complexity of structures. The state of construction production in the country can be judged on the state of the economy of this country as a whole. Now the urgent issue in the world is the use of new composite materials in the strengthening of building structures. Such materials include non -metallic fittings, laminates, nets and canvases based on high -strength fibers. In this case, the own weight of fiber materials is slightly small. Only units of the above researchers performed enhancement of experimental samples under load, so the influence of the initial stress-deformed state on the work of the structure after amplification was practically not studied.

Strengthening of building structures of historical masonry buildings in Syria with carbon fiber reinforced polymer (CFRP) rods and stainless steel helical rods

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.

INSPECTION OF THE TECHNICAL CONDITION OF A NON-RESIDENTIAL BUILDING

This article contains a survey of the building in a. Sary-Bulak. A detailed visual examination of the object of study, an assessment of the technical condition of the main loadbearing building structures of the building, an analysis of the causes of defects and damage, and preliminary installation of the technical condition category were carried out. As a result of the survey, design recommendations, measures for the restoration or strengthening of building structures were developed.

REHABILITATION OF HISTORIC HALF-TIMBERED WALLS WITH COMPPOSITE MATERIALS BASED ON HIGH-STRENGTH

The major requirements for present day cultural heritage conservation include the minimization of interventions in historic structures, non-invasiveness and, last but not least, reversibility of rehabilitation and strengthening interventions. Due to these requirements, composites based on high-strength fibres and epoxy resin are increasingly applied during the rehabilitation, renovation and strengthening of building structures. The article points out potential applications of these materials in the renovation, rehabilitation and strengthening of half-timbered constructions.

Analysis of Seismic Isolation Device for Earthquake Resistant Building Structure Reinforcement

To enhance the seismic performance by using the traditional method of building function, will affect the building using function. Therefore, not affecting the building using performance, the isolation device for seismic reinforcement, only through the underground part of the building project can solve these problems. In this paper, through government building envelope analysis and time history analysis, the seismic strengthening of building structures under earthquake action effects before and after the isolation device, fully explain the role.
