New types of wood based building materials to which the CLT refers require an accurate evaluation of the strength of varioustypes of connections. CLT panels connections with glued-in steel rods are of interest due to the possibility of creating quickmounted and rigid joints in the factory. Since the CLT have the structure of the perpendicular orientated boards in adjacentlayers, the strength and behaviour of the pasted rods is difficult to predict. The purpose of this study was to establish thestrength of the glued-in rods by pull-pull tests with different locations relative to the boards layers in the cross-section of theCLT panel. Diameter of all considered steel rods was smaller than thick of timber planks 30 mm in 5-lyers CLT specimenswithout gaps and stress relieves. Anchored length of rods in all specimens was 100 mm by using two component epoxy adhesive system.

Problems in designing hydraulic brake systems of cars have been analyzed. The study of the braking process has conductedconsidering the distribution of forces on the axles during braking. The general support model research and support geometriccharacteristics are developed. The calculation of the car brake system has been conducted that enables to determine the load onthe caliper during the braking process and using graphic dependencies, and to determine the concentration of maximumstresses in the mounting areas of the support. Based on analytical studies in the Autodesk Fusion 360 3D Modeling program,a design has been implemented that features a smaller metal capacity at the expense of rational design and providing uniformstrength across the entire surface. Adaptive technologies also significantly accelerate the production of new parts due to thelack of need for the production of auxiliary equipment, such as molds.

During the exploitation of equipment and piping systems of sulfuric acid, shale, metallurgical, mining, energy and other industries, the metal of a number of structures directly contacts with sulfur-containing agents at high temperatures. This resultsin intense corrosion, loosening and saturation of the surface layer of metal with sulfur (elementalor in the form of variouscompounds, including sulfides, iron, oxides) with a concentration of up to 0.6%. Repair welding of such metal at its partialreplacement is connected with the big labor costs caused by necessity of mechanical removal of a surface layer, as withoutthis operation in weld metal by standard electrodes hot cracks, pores and notfusion are formed.

A considerably distinctive deformed five-storeyed three-section brick residential house erected over 40 years ago on drivenprismatic piles combined by a strip grid foundation by a standardized project is under investigation. The geotechnical monitoring results of the building's technical condition are presented. Methods and results of the instrumental control analysis ofthe piles' actual length and visual evaluation of their integrity are presented. The causes of the foundations base's excess deformation were determined: the inability of the piles' tips to reach the designed mark; the piles' destruction during their immersion in dense sands; rupture of the primary thermal network, which led to "negative friction" effect on the piles' lateralsurface, etc.

This paper deals with the study of reliability of quasi-homogeneous bolted joints of the body of thin-walled constructions ofthe steel silos. Heterogeneity of this unit can be caused by number of reasons, in particular by presence of bolts of differentstrength in joint. In such case the reliability of the system is determined trough the probability of trouble-free work of the coefficient of the critical factor. The general conception of stochastic calculation consists in using the Monte-Karlo simulationprocedure for the samples of random values of the large volume. It was formed the system of conditions, under which the reliability of joints is provided and analytical expressions for the value of coefficient of the critical factor is got, and also madepractical calculation example with the following graphic presentation on a special coordinate plane – a critical stochasticscale. It was illustrated that random presence of bolts of less strength in field joint rapidly increases the risk of refusal.

The article presents the experimental study results of flat intercolumn plates loading work peculiarities of the beamless overlapping developed system. The attention is paid to the design of the experimental designs of the bearing structure with thebevelled platforms of suspension on the outer perimeter of the span plates. The technique of performing experimental studiesis presented. The conducted researches enabled to establish the nature of deformation and destruction of intercolumn plates asa separate element in the developed system of beamless overlapping. In this case, the magnitude of the compression deformations decreases to the point where the test specimens rest on the supporting blocks. It confirms the assumption of the transferof load from the spacers to the intercolumnar on the principle of "linear hinge". Attention is paid to the fact that the achievement of the bearing capacity is not accompanied by the process of destruction, but is characterized by significant movementsof the flying part of the plate in the vertical plane.

The methods of intensification are analyzed and it is established that it will be rational in this case to pump carbondioxide into the reservoir. Its influence on a bundle of oil and water is determined. The results of the statistical processing ofthe change of the debit before and after injection of carbon dioxide, the influence of the volume of gas injected into the wellfrom the seperate permeability of the reservoir, as well as the expected rate of wellbore after injection, are presented.

The data of experimental researches of the rigidity of reinforced concrete I-beam elements with normal cracks at the action on them of the twisting moment have resulted in this paper. It is shown that the dependence "torque-twist angle" is almost linear. Significant nonlinear deformations appear in the last stages of loading before failure. Therefore at normative torques, it is recommended to consider the work of reinforced concrete elements of the I-beam cross-section with normal cracks linear. It is shown that the presence of longitudinal reinforcement affects the strength and rigidity of beams with normal cracks. Quite a large part of the external torque is perceived by the pin forces in the longitudinal reinforcement. The difference between the external torque and the moment of the pin forces in the armature is perceived by the upper shelf of the I-beam element. In the absence of longitudinal reinforcement, the upper shelf can collapse at loads much smaller than the destructive load of beams with longitudinal reinforcement.
