Published: February 2022

Abstract
Over the past 10 years, the population of Russia has had an increased interest in amateur training. There are many wellness and sports complexes being constructed allowing people to comfortably do sport. This article shows the analysis and identification of characteristic features of volumetric planning solutions and architectural and town-planning design of such complexes. The modern sports and wellness center (SWC) should have versatile and multi-functional planning solutions. Analysis of the objects showed that a modern SWC has a small area of up to 2,000 sq.m. and the number of floors vary from 1 to 3. The complexes are aimed at a wide range of users, at different age groups, in addition to multi-purpose gyms, there are some specialized ones included in the layout: tennis courts, gymnastics, volleyball, swimming pools and skating rinks, as well as additional recreation functions: SPA treatments, baths, nutrition. The structural system of buildings is metal frame one.
The volume solution for the complexes varies from simplified to complex forms, facades have various finishing materials and color schemes. The variety of solutions allows to create unique buildings, but at the same time, it makes it difficult to visually identify buildings as sport and wellness centers. The necessity of creating a unified system of visual identities for mass sports facilities was identified.

Analysis of the General Stability of Buried Pipelines in the Longitudinal Direction Taking into Account the Peculiarities of Their Construction and Operation
Authors: Kozhaeva K V , Azmetov Kh A , Pavlova Z Kh 
Published: February 2022

Abstract
Main oil and gas pipelines should be checked for overall longitudinal stability. In this case, the longitudinal compressive force in the cross-section of the pipeline, leading to the loss of its stability, is determined by the effect of a positive temperature difference in the metal of the pipes and the working pressure in its cavity. The longitudinal critical force, at which the loss of longitudinal stability of the pipeline occurs, is determined according to the rules of structural mechanics in the plane of the least bending stiffness of the system taking into account the constructive solution of its laying. The value of the longitudinal critical force of a buried pipeline depends on the geometric characteristics of the pipe, its weight with the pumped product, the parameters of curvature of the longitudinal axis of the pipeline when it is laid along the terrain, and the resistance of the soil to its longitudinal and transverse displacement. During operation, due to a decrease in the resistance of the soil surrounding the pipeline to its movements for various reasons, a decrease in the critical force occurs. Loss of stability of a buried pipeline occurs in the plane with the least bending stiffness of the system. With the help of theoretical studies of the general stability of buried pipelines, analytical dependences of the longitudinal critical force for a buried pipeline were obtained on the basis of taking into account the curvature of the longitudinal axis of the pipeline during construction and reducing the resistance to displacement of the pipeline during its operation for 5 different design schemes.

Equation of kinetic energy of impulse rotator allows to determine mutual influence of design elements on rational use of supplied pulse energy for useful work. Positive qualities of kinematic torsional vibration exciters are noted, the main of which is organization of force pulse regularity and its considerable force possibilities of pulse creation. A generalized graph of the change of productivity and wear of the working element of the pulse converter compared to the static one is given.
Features of impulse rotators with kinematic excitation of torsional oscillations make it possible to change the mode of work performance, to apply low-energy processes of individual operations. Transportation way of destruction products by the screw with use of an impulse rotator on breeds above average fortress excludes use of the compressor. Machines with rolling and spring impact tools do not correspond to the screw method of destruction products discharge and require compressor use.

Published: February 2022

Abstract
With the enormous length of district heating networks, the need to restore heat pipelines is constantly increasing. Elimination of accidents requires much higher material costs than their prevention, therefore, timely detection of hazardous areas in an emergency relation and their replacement during preventive repairs is important. In this regard, it is necessary to predict the actual state of individual elements and the heat transportation system as a whole for the subsequent decision-making on its operational reliability. The aim of the work is to increase the reliability of heat supply systems by improving the method for predicting potentially hazardous sections of heat pipelines. The article presents a method of qualitative prediction of the state of underground heating mains, based on a comparison of heat losses calculated on the basis of thermography data with the values of heat losses determined from test data.

Abstract
In industrial production for the storage or processing of various bulk materials such as compound feed, grain, coal, crushed stone, sand, rocks, etc. use different containers and bins. Depending on the physical and mechanical properties of materials, containers and bunkers of various types are used.
When designing tanks and bunkers, various engineering solutions are used to save material and reliable strength of the entire structure of tank structures. One of these solutions is the installation of stiffeners on the surfaces of the hoppers, which gives additional rigidity to the entire structure and saves material by reducing the thickness of the hopper walls.
In order to select the required stiffeners, a number of studies are required. The purpose of these studies is to establish the most optimal parameters of stiffeners, such as width, thickness, spacing, steel strength class, as well as to assess and substantiate the economic feasibility of using the selected ribs in the structures of tanks and bunkers.
A technique has been developed that allows one to determine the main parameters of stiffeners, setting constant parameters set depending on economic and technological conditions. In our case, the geometric dimensions of the bunker and the spacing of the ribs were used as constant parameters.
