Design of bending concrete elements with rigid reinforcement

The article considers the main points of the construction of bent reinforced-concrete elements with rigid reinforcement in the form of metal-profile double-T or T-section paired. The possible application methods the rigid reinforcement in conjunction with flexible rods, whose task is to eliminate the possibility of spalling (flaking) of concrete from metal rolling profiles. The methods provide concrete collaboration and metal-rolling profile by means of the use of short stacks from the corner, as well as ensuring the anchorage all rolled sections in the body structure by the use of channel-short stacks at the ends of the profiles

Methods of providing combined action of concrete and metal rolled stock in reinforced concrete constructions with rigid armoring

The author studies pilot research works into combined action of concrete and metal profiles in reinforced concrete constructions with rigid armoring carried out by scholars from both near and far foreign countries. The main methods of providing co-action of the two materials in the compression elements are outlined through the example of columns and flexural elements through the example of a T-beam. The advantages and disadvantages of the proposed methods are analysed

The Use of Non-Destructive Methods of Control in the Examination of Existing Ferro-Concrete Buildings and Facilities

Currently thanks to the reconstruction it is possible to modernize most of the technically and morally obsolete buildings. However, it is worth noting that in the reconstruction of existing buildings and structures, an important stage is the determination of the parameters of the reinforcement and concrete (the thickness of the protective layer, the location of the reinforcement, the diameter, etc.). In order to perform verification calculations and subsequently determine where and how to strengthen it is necessary to conduct whether they are needed. This is especially important, as in the reconstruction of buildings and structures (associated with the construction of new floors), and when the object is replaced by a functional purpose

The anchorage of untensioned reinforcement

The article concerns the main factors that influence the anchorage of untensioned reinforcement and it also presents the analysis of the effect of web and confinement reinforcement in welded reinforcements made by resistance spot welding, on the anchorage of longitudinal reinforcement EN 1992-1-1-2009

Influence of heterogeneity of the reinforcing bars in the cross section on the testimony of portable hardness

It is considered one of the most important trends in the field of inspection and quality control of existing structures.The basic methods for determining the class of reinforcement in concrete examination of buildings and structures. The possibility of using portable hardness in practice. Attention is paid to methods for treating the side surface of reinforcement stem. Experimental data showing the unevenness of reinforcement strength readings across the section depending on the depth of cut. Theconclusionsabouttheneedforadditionaltesting
