CRITERIA FOR EVALUATION OF VENTILATED FACES QUALITY
NETISHINA K.A., RYAZANOVA G.N.
Abstract

The article describes an approach to probabilistic and physical modeling of walling reliability taking into account temperature, moisture and operation conditions, structural elements load specifi cation, reliability indicators and failure probability. The durability (service life) is taken as the main reliability indicator. The man-made and climatic impact on building construction durability is studied. It is proved that ventilated faces are a modern design solution for construction of new buildings as well as reconstruction.

INFLUENCE OF MAJOR LOWLAND WATER BASINS ON GEOTECHNICAL STATUS OF LOESS SOILS
BARANOVA M.N., MALTSEV A.V., VASILYEVA D.I.
Abstract
The prevalence of loess soils in North Eurasia steppe zone causes their frequent use as building foundations. In this regard their geotechnical features are of particular importance. In European part of Russia loess soils are widespread in mid-Volga region which present at the moment tandem reservoir system created more than 50 years ago. In reservoir area major lowland rivers show rapid increase of groundwater level that has negative consequences in the case of loess soils. In Samara region there are two great lowland water basins on Volga river (Kuibyshev and Saratov Reservoirs) which have a great impact on environment. Loess soils geotechnical features, geological processes, material composition and microstructure as well as their changes in underfl ooding are described.Underfl ooding infl uence on loess soils in urban development conditions are studied.

PECULIARITIES OF DESIGN AND OPERATION OF WATER SUPPLY SYSTEMS OF HIGH-RISE BUILDINGS
SAYRIDDINOV S.S.
Abstract
In this article the problem of design and operation of water supply systems for high-rise buildings in Russia, including in Togliatt i, is considered. The system of water supply of highrise buildings in modern design conditions is substantiated. It is noted that the existing design methods are based on the norms of the last century, without taking into account modern developments in the fi eld of sanitary equipment and the requirements for resource saving. It is substantiated that in order to above-mentioned problems solution it is necessary to study the development trends of the regulatory base in the fi eld of high-rise construction; to determine the operational features of high-rise building water supply systems; to reveal factors aff ecting resource conservation in the water supply system of high-rise buildings; to study effi ciency of pumping units operation and peculiarities of their regulation; to evaluate the water-saving eff ect from the use of modern water-fi ttings.

INFLUENCE OF TYPE OF CRIMEAN QUARRIES CARBONATE WASTE ON DURABILITY, СURING TIME AND STRUCTURE FORMATION OF SLAG-LIME CONCRETE ON THE BASIS OF SOLUBLE GLASS WITH SILICATE MODULE 1,5-1,7
SVISHCH I.S., NOSATOVA E.V.
Abstract

In the article the infl uence of carbonate waste on durability, curing time and structure formation of slag-lime concrete of diff erent compositions with diff erent curing conditions on the basis of soluble glass with silicate module Mc=1,5-1,7 is considered as well as Crimean quarries stone-cutt ing waste. Slag-lime binders are diffi cult in-use because of curing time and its infl uence on concrete brick durability. One of ways of sett ing time regulation lies in introduction of some stone-cutting waste in blast-furnace grained slag before grinding. The studies of stone-cutt ing waste infl uence on curing time, durability and structure formation of slag-lime binder and concretes on its basis are able to show mechanism of curing time regulation and it will work to correct technological parameters of construction items production. The phase composition is studied with help of the diff erential thermal, x-ray diff raction and microstructural analyses.

RYBAKOVA D.S.
Abstract
The paper is dedicated to investigation of creative approach of Portuguese architect Alvaro Siza Vieira. As a part of the study massings of the most modern objects designed by Siza in different countries in the latest 10-15 years are analyzed. Critics and theorists opinions are presented as well as commentaries of the Maitre himself. For Alvaro Siza urban environment is the context of architectural objects in most cases but interplay of buildings and nature context is original and equally interesting. According to analysis report we managed to formulate number of principles that were applied by Alvaro Siza to design diff erent objects in natural, urban or historical environment ad to form graphical schemes and models illustrating these principles.

ZIMIN L.S., YEGHIAZARYAN A.S.
Abstract
The article views energy saving as motive force for sustainable economic growth in Russia. Electrical energy is a product which determines performance indicators of industrial enterprises, production quality, equipment and apparatus reliability and even mental health of people. The role of education and competence development in the fi eld of energy saving is highlighted. The optimization of energy intensive technologies is also very eff ective. The authors prove that electrical energy is the most ecological energy form, it is more eff ective for usage than mineral fuel. Possible ways of energy saving are studied at operating objects as well as objects in design.
