Резонансные характеристики акваторий морских портов

M.J. Zheleznyak, I.G. Kantardgi, M.S. Sorokin, A.I. Polyakov
Resonance properties of seaport water areas (rus)

The article discusses the modern methods of determining the mode of low-frequency oscillations in a port causing harbor oscillations, using as an example the dry cargo area of the Taman seaport and the Gelendzhik seaport that are currently under design. These ports were scanned for risk of harbor oscillation occurrence through an existing regulatory procedure which uses significant simplifications.

3D performance of a seepage control wall in dam and foundation (rus)

This article analyzes the results of numerical modeling of the stress-strain state (SSS) of a grout curtain carried out by the cut-off wall method in the dam foundation and body of the Yumaguza hydroelectric complex. On the river channel section the wall cuts through not only the riverbed deposits, but also the lower part of the dam. On the right-bank section the wall cuts through only the upper part of a very thick layer of clay soils.

ANALYSIS
Моделирование процессов энергообмена в системе дорожное покрытие – транспортное средство

A.M. Kirillov, M.A. Zavialov
Modeling of energy dissipation processes in a pavement – vehicle system (rus)

The law of conservation of energy for a ‘pavement – vehicle’ system manifests itself primarily in the fact that for any temperature and operating conditions of a road asphalt concrete pavement the potential energy of gravity and the kinetic energy of a vehicle are partially transformed upon contact with the road pavement into elastic deformation energy or thermal energy, while a part of the energy dissipates.

CALCULATIONS
Расчет дорожных одежд по критериям ровности. Часть 1. Обоснование норм ровности асфальтобетонных покрытий

V.N. Gercog, G.V. Dolgikh, N.V. Kuzin
Calculation criteria for road pavement evenness. Part 1: substantiating the flatness standards of asphalt concrete pavement (rus)

This article gives an overview and analysis of the works aimed at finding empirical dependencies linking the indicators of longitudinal and transverse evenness with the parameters of the deformability of road constructions and its individual elements. We list the data of field experiments and laboratory studies of triaxial deformation of materials by a repeatedly applied load. The methods of calculating the deformation based on rheological models, including the theory of hereditary creep, have been analyzed.

Анализ прогиба решетчатой балочной фермы распорного типа

M.N. Kirsanov
Analysis of the deflection of a strut-type lattice girder truss (rus)

The analytical dependence of the deflection of a statically determinate plane elastic truss with a uniform loading of the upper zone has been found. Forces in rods were determined using the joint isolation method. A system of equilibrium equations has been compiled in matrix form. Midspan deflection has been calculated based on the Maxwell-Mohr formula. All character conversion has been executed in the Maple computer algebra system.

Сравнительный анализ аналитических решений задачи о прогибе ферменных конструкций

D.V. Tinkov
Comparative analysis of analytical solutions to the problem of truss structure deflection (rus)

We have found new exact analytical expressions of the deflection of various plane truss structures and analyzed the existing ones. Truss deflections have been calculated by the Maxwell-Mohr formula assuming the elastic behavior of the truss elements using the method of induction on the number of panels. We have carried out a comparative analysis with known solutions and studied the quantitative and qualitative features of solutions.

STRUCTURES
Прочность просечно-растяжного профиля

A.S. Sinelnikov
Reticular-stretched thermoprofile: a numerical and analytical study (rus)

There are certain advantages to utilizing thin-walled cold-formed profiles in construction, as their use enables construction in all weather conditions, and allows to achieve better assemblage accuracy and to reduce costs. Thermoprofiles have slots in webs that decrease thermal flow through the web, but have a negative effect on the strength of the profiles. The reticular-stretched thermoprofile is the new type of thin-walled perforated profile.

Анализ работы несущих элементов из алюминиевых сплавов (англ.)

Behaviour analysis of load-bearing aluminium members

Aluminium is one of the traditional structural materials. Structures made of aluminium alloys are widely used in the civil engineering for erection of new civil and industrial buildings and reconstruction of the existing ones. Increased corrosion resistance, stability of mechanical properties at negative temperatures, lightness and increased durability are the main advantages of aluminium alloys as the structural materials.
