“…The concept of the design strength of reinforced concrete and its application are given in the work [19] for calculating the bearing capacity of members subjected to plane bending. The essence of the considered approach is that reinforced concrete is considered as a composite that has a certain strength characteristic -the design strength of reinforced concrete.…”

Based on the design assumptions according to Eurocode 2, the concept of determining the value of the design strength of reinforced concrete has been developed for calculating the bearing capacity of reinforced concrete members subjected to biaxial bending. The theorem on the parallelism of the planes of internal and external forces action is applied. The considered design cases are for the most expected forms of the compressed concrete areas, which are characteristic for biaxial bending of beam members. The value of the coefficient of influence of biaxial bending on the characteristics of the member of rectangular section with triangular and trapezoidal forms of the compressed concrete area is obtained. A methodology for calculating the bearing capacity of biaxially bended members based on the application of the design strength of reinforced concrete is brought to the engineering level of application. An example of a calculation is presented, which demonstrates the convenience and effectiveness of the developed method. The proposed method of calculating the bearing capacity of beam member under biaxial bending is approved by comparing the results of calculations with experimental data for 12 samples of biaxially bended beams.

The purpose of this study was to optimise directional drilling of exploration wells in the Caspian Sea area of Turkmenistan to improve efficiency and reduce environmental impact. The methods employed include the analytical method, classification method, functional method, statistical method, and synthesis method. The study analysed the experience of drilling a directional exploration well in the North Goturdepe field in South-West Turkmenistan with a bottom hole offset of more than 1000 m from the wellhead under anticentral intracavity pressure conditions. The findings of the study confirmed the effectiveness of the new methods to increase hydrocarbon production, reduce time costs, and mitigate the negative impact on the natural environment. This study emphasised not only the significance of modern technological solutions in the energy industry but also their substantial contribution to the sustainable development of the region and energy security.

The relevance of the study is to develop an effective system for controlling the pressure in the air supply in motorised breathing apparatus to ensure effective protection of employees from dangerous aerosols and improve their health. The goal was to create an automated air pressure control system in a motorised breathing apparatus using a proportional-integral-derivative controller. For this purpose, the simulation method was used. In order to avoid unforeseen situations of deterioration of the level of protection, the structure of the pressure control system of a motorised respirator has been developed with the selection of the appropriate controller based on the obtained dependences of the influence of the parameters of the breathing mode and the amount of pressure in the under-mask space of the respirator, which ensures an appropriate comfortable mode of operation. This allowed developing a simulation model with a PID controller that would provide the appropriate pressure values within the permissible limits (50-370 Pa). It is proved that the proportional-integral-derivative controller maintains the pressure in the respirator mask within certain limits both with an increase and with a decrease in the control signal, preventing excessive fluctuations in the controlling variable, which leads to an extension of the service life of the filter elements and a reduction in electricity consumption for the operation of the fan motor. Based on modelling the operation of the pressure control system in different modes of operation, it is shown that when using a PID controller with defined parameters, the system provides compensation for changes in air
