Authors: Topchiy D , Lapidus A 
Published: December 2019

AbstractThere are renovation and conversion programs currently under way in all major Russian cities with million-plus population. Based on the findings of integrated survey of built-up areas, existing buildings and their architectural and space planning concepts, as well as the outdoor utility systems, and also taking into account economic expediency, developers make decisions on demolition of buildings or converting them into non-production facilities. Despite the available extensive international experience and a wide spread similar trend everywhere in Russia, no system-based, research-backed approach to such projects is known to exist. The article discusses the basic principles of forming a system that permits the interconnection of project participants, organizational structures and information bases, leading to an increase in the effectiveness of the project’s main indicators, provides an opportunity for managers to quickly evaluate the activities of project participants and manage individual modules of the system. The main elements of the system are: conversion; information support, as well as organizational structure. The harmonious synthesis of these elements makes it possible not only to evaluate the existing level of efficiency, but also to design a system of interconnections, as well as to control it. The main basis for the formation of the possibility of designing this is the differentiation of the existing system and its elements into separate organizational and managerial modules. These modules allow to make their quantitative and qualitative assessment, which in turn, makes it possible to control the entire system.

Published: December 2019

Abstract
The industrial processes are noticed to be accompanied by the contaminators’ emission inter alia the high-dispersion aerosols. To reduce the amount of the dust emitted into the atmosphere, it is advisable to provide the cleaning devices installation as a part of exhaust ventilation systems. Entrapped substances may be recycled or returned back to production, and it’s especially valuable if rare and expensive row materials are used in manufacturing. Trapping aerosols of fine dispersion with simple and reliable mechanical devices with low energy consumption is quite important. The proposed apparatus for the dust particles cleaning emissions is with a dispersion of 0,1 μm. Device operation is based on enlargement and following entrapment of solid fine particles on slabs perforated by the way of chinks and irrigation water contaminated air by the nozzles with the particulate composition of from 2,0 to 10 μm. The chinks width on the first and the second slabs, displacement of chinks hole axes of the first and the second slabs relative to each other and distance between slabs ensure creation of increased coagulation and stable sedimentation of particles are discovered.

Published: December 2019

Abstract
The main design flaws in terms of protection against young fish entering the water intake bucket, sediment inflows, sludge and floating objects, which largely do not provide the current regulatory environmental requirements for ensuring environmental safety (ES) of water intake technological complexes (WITC) directly interacting with the natural water environment (WE) of the water body (MPWS) as a part of the natural technical system (NTS) “WE-WITC-MPWS” were identified during the comprehensive studies to assess the functional effectiveness of existing water intake structures (about 44) of multi-purpose water supply systems (“MPWS.”) of urban farms and settlements in the Lower course of the river Don from the Tsimlyansky reservoir to the mouth (Azov).
In order to ensure the operating “WITC” operating systems based on the results of constructive studies using domestic experience in the use of high-strength synthetic fabric materials, an innovative design of a water intake structure in the form of a soft floating structure (SFS) has been developed providing the regulatory requirements on the main indicators of ES by 85%-95%.

Operating the hot water supply system problems during transfering the hostel to the apartment house status
Authors: Antsiferov S A , Lushkin I A , Usmanov E A 
Published: December 2019

Abstract
The energy infrastructure modernization is a complex social and technical problem requiring an integrated approach. After analyzing the hot water system operation in a residential apartment building, being previously a hostel, the reason for the temperature regime violation was determined. In connection with the building status change, the residents number has significantly decreased, the service block, which led to a change in water consumption conditions has been eliminated. In addition, the requirements for minimum water temperature in centralized hot water systems have changed. The question of using a dead-end hot water supply system possibility, provided by the project or its reconstruction into the circulation network, was considered. The studies were conducted in accordance with the methodology described in MIC 4.3.2900-11 “The centralized hot water supply systems hot water temperature measurement”. There was a discrepancy in the temperature coolant standard indicators at the dismantling points on different floors of the building. The difference in temperature at the input (the heat meter and thermometer readings) and at the end user is associated with additional water cooling in the supply pipes of the domestic hot water heating system. When transferring the public buildings to housing stock, it is necessary to revise not only water consumption rates, but also the hot water supply scheme in general. The lack of circulation leads to waste of hot water and increases the cost to the consumer. To ensure the required temperature standards for a full day in a dead-end hot water supply system, which is provided for by the project, continuous dismantling of the water is required, which is difficult to achieve with a changed building status. The resolution of the problem is possible only when the domestic hot water heating system is switched to the circulation mode with the circulation piping and the circulation pump installation.
The dynamic wave coefficient
Authors: Yaksubaev K D , Kochergina D D 
Published: December 2019

Abstract
Seismic calculations nowadays are carried out without accounting for the wave nature of the problem. All the seismic wave energy is assumed to be transmitted to the structure, but the wave part is reflected. The oscillating structure, in turn, affects the soil and gives back some of the energy to the soil. Thus failure to the wave nature of the problem results in to the excess of the calculated seismic loads over the real loads. Moreover, the magnitude of this excess is unknown.
The paper presents a solution of the wave effects determining problem. To account for the wave effects the system consisting of the soil seismic vibrations wave equation and the structure vibrations equation is solved. Thus, the task seems to be very difficult.
The purpose of the work is to develop and analyze compact exact solutions of the above task, since compact exact solutions can be put into practice of engineering calculations.
In the works of well-known authors an exact solution of the system of equations consisting of a wave equation describing the joint longitudinal seismic vibrations of the earth's crust and the equation of oscillation of the structure in the form of a point insert was obtained.
But the numerical calculations for the exact solution were not carried out.
The abstract solution analytical calculation from the work [1] for a concrete initial form of a seismic wave was carried out in this paper. The initial seismic wave is selected in the truncated harmonic function form. This choice allowed to derive a new coefficient – a dynamic wave coefficient. Numerical calculation of the wave dynamic coefficient showed that the classical non-wave methods for calculating seismic forces give overstated assessment. The dynamic coefficient depends on the properties of the soil.
In general, it also depends on the material of which the structure is made. For example, if the soil passes only high frequency seismic vibrations, it may be useful to select new materials to create a low frequency structure.
But the exact solution of the wave seismic stability problem is difficult even in the initial formulation. Therefore, in the present work a detailed analysis of the obtained exact solution was carried out.

Published: December 2019

Abstract
The problem of increasing the efficiency of the construction machines functioning continues to be relevant in modern conditions. The downtime of construction equipment, in particular, of a single-bucket excavator (SBE), leads to a violation of the terms of work and to significant economic losses. One of the most loaded elements of a single-bucket excavator is a boom. Increasing the reliability of its work reduces the number of the machine failures greatly, and as a result reduces the cost of repairs and equipment downtime. The gamma-percentage fatigue life of the components, in particular, a single-bucket excavator boom, must correspond to the resource before discarding the machine. To prevent failures, it is necessary to increase the gamma-percentage fatigue life of the boom to the optimum value by changing the steel grade and the geometric characteristics. This will reduce the repair expenses and the damage from the downtime of the excavator as well as the mechanized machinery complex associated with its operation, thereby determining the relevance of the work presented.
