CRITERIA FOR EVALUATION OF VENTILATED FACES QUALITY
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.

CALCULATION OF BEAM-STRIP FOUNDATION ON CUSHION COURSE THROUGH HYPERBOLIC- CIRCULAR FUNCTIONS
Abstract
Many methods of calculations of beam-strip foundations on cushion course are described in academic literature. This article views one of the most eff ective methods - the method of calculation of beam-strip foundations on cushion course through hyperbolic-circular functions. The procedure of calculation under diff erent condition variants in initial and terminal cross section is presented. The proposed method is one of the most simple and eff ective calculation methods which permits to simplify the procedure of calculation of beam-strip foundations on cushion course and to obtain more consistent results and to approximate design conditions to practice.

DEVELOPMENT TRENDS AND CREATION OF NEW BUILDING MATERIALS
Abstract
Trends, regularities and eventual development ways of construction materials, items and structures revealed on the base of patents fond and recent researches analysis are shown in the article. Scientifi c literature sources analysis proves that construction materials and structures development and their production technologies are obeyed some regularities which can be studied and used for construction materials and structures perfecting. It should also be taken into account that materials from production to use in construction undergo signifi cant changes - from liquid, pseudoliquid and fl uid state to hard state. Final product should meet requirements of strength, durability, damage tolerance. The most advantageous ways of constructional materials perfecting are revealed. Based on the research results every next step in especial materials and structures development can be predicted.
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
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.
ECOLOGICAL PROBLEMS SOLUTION DURING EXTRACTION AND PROCESSING OF RAW MATERIALS
Abstract
The article briefs on human impact on the environment during raw materials open mining and primary processing: carbonate rocks, clays, sands, etc. The main sources of pollution are revealed. It is found that man-made mineral formations which consume great territories and change relief make the principal impact. The main task for environmental load decrease on quarrying areas is determined: reducing or elimination of man-made formations. The authors recommend to monitor the state of natural environment for the purpose of ecological processes prediction and management. The integration of research results into diff erent construction materials production is the mosr eff ective variant of problem solution.
ANTHROPOCENTRICITY PRINCIPLE AS AN INSTRUMENT FOR PEDESTRIAN SPACES DESIGN
Abstract
The principle of anthropocentricity implies the organization of barrier-free pedestrian space corresponding to norms of walking, and criteria of quality and comfort for multi groups. The defi nition of pedestrian spaces and their more advanced phase - integrated pedestrian spaces is proposed in the article. The physiological capabilities of the pedestrian, including people with limited mobility, which form the parametric characteristics of pedestrian spaces, such as radius of the walking distance, absolute and to concrete objects, are identifi ed . The development dynamics of pedestrian spaces quantity and quality parameters over time is revealed.
Architectural order and people. Tribalism and environmental isolation of Russians
Abstract
The article deals with the revealing of the factors aff ecting the creation of the image of «modern Russian architectural order». The features of Russians adaptation to this image in everyday life are described. Characteristic properties of organization, formation and interaction of modern «order groups» with city and between each other are viewed, characteristic symptoms are described and new terms in this fi eld of study are introduced. The paper is followed by summary and illustrations.
DESIGN TECHNOLOGIES ROLE IN ARCHITECTURAL ENVIRONMENT AND SOCIAL PROGRESS
Abstract
In the article the role of design and its instruments in architectural environment is viewed, design goals are scheduled, design place in social progress is determined. The research deals with key aspects of profession of designer in context of modern environment and cultural necessity. The problem of design methods integration in society by means of involvement principles is studied. It is proved that designer plays a role of communicator and new technologies provider and this fact conditions specifi city of design methods in designer profession. The solution for the problem of architectural environment depersonalization and its subject fi lling is proposed on the base of latest achievements of technology and humanities.
SOCIAL ECOLOGY OF A CITY: FEATURES OF LIVING ENVIRONMENT FORMATION
Abstract
The interaction between internal and external spaces in modern architecture of low-rise residential house is shown. The features of spatial boundaries and their resources for low-rise residential architectural objects are studied. Ecological problems of spatial boundaries formation are revealed. Current researches in the fi eld of architecture ecology are viewed. The major criteria of evaluation of sustainability of architectural boundaries of low-rise housing are determined. The principle of nature conformity of space in low-rise architecture is revealed. This principle is studied on two levels - methodological and practical, and it supposes internal space formation in according with nature environment factors and its ecological status.
