A study of the properties of dispersed-reinforced concrete and a study of the effect of dispersed reinforcement on the operation of structures was carried out, mainly with a static load of the same sign. Based on the results of experimental studies, a comparison was made of the work of dispersed-laminated structures under alternating dynamic action of high intensity with the work of reinforced concrete beam elements under similar influences. The results of experimental studies of cubes and prisms for static and dynamic compression are also presented. The results of experimental studies allow us to conclude that there is a significant effect of dispersed reinforcement on the operation of structures under the investigated influences and the feasibility of combined reinforcement of structures. The use of dispersed reinforcement in structures will increase the resistance of structures to such influences.

Unsaturated Polyester Resin Mortar

This research is aimed to investigate the flexural behaviour of patched reinforced concrete beam with patching material made from unsaturated polyester resin mortar. The variable studied is the dimension of patching zone as compared to the control beam (without patching). Based on the load-deflection observation of the beam under a four-point bending loading, it is confirmed that the flexural behaviour of the patched reinforced concrete beam is similar to that of control beam at a loading up to about peak load. After this load the patched reinforced concrete beam tends to behave more ductile. The patched reinforced concrete beam show less cracking density compared to control concrete.

Ultimate Limit

The research aimed to study methods for calculating wood-concrete beams of rectangular cross-section when testing building structures according to the ultimate limit state. The article focuses on the comparison of theoretical methods for calculating structures and considers several methods of fastening the samples of a typical wood-concrete beam. There were obtained experimental data of the ultimate limit state for each sample and carried out a comparative analysis of the most advantageous scheme of fastening the sample parts. The scientific novelty is in the development of an algorithm for calculating composite wood-concrete beams of rectangular cross-sections. As a result, numerical comparison of the values for calculating a typical wood-concrete beam using two of the methods under consideration was given, experimental studies were carried out, as well as a comparative analysis of the obtained theoretical and experimental results.
