Social Housing at a New Stage of Enhancement

It is shown, that problems of the lack of housing and material means of the population cause the increased demand for economy-class housing not only in the sector of state financing of construction programs, but also in the sector of private investments. Possibilities of the evolution of economy-class housing within the limits of physical depreciation are considered. It is concluded, that at present for constructing the economy-class housing it is necessary to turn to structural systems which make it possible to change the layout of apartment at any stage. The universal structural system of panel-frame housing construction (SPFHC) of different modifications with bearing cross walls, bearing longitudinal walls, bearing staircase and elevator section for houses of tower type, with bearing elements of the frame – pylons, columns, beams and girders – developed by TSNIIEPzhilishcha is described.

Keywords: economy-class housing, industrial housing construction, housing, structural system, panel-frame housing construction, SPFHC)

The use of the universal system of large-panel housing construction (USLPHC) makes it possible to flexibly adapt to concrete conditions of insolation when positioning panel houses on a concrete construction site. An example of obtaining the necessary space-planning arrangement for existing conditions of insolation owing to the construction of bay windows in non-insolated flats is presented. An example of positioning of a meridional block-section instead of a latitude one is presented. Using the USLPHC in one unit of shuttering with unchangeable external sizes the manufacturer has the opportunity to produce dwelling houses with maximum advantageous space-planning arrangements and free lay-out both for one-family flats and entire floors.

Keywords: universal system of large-panel housing construction, insolation, space-planning arrangement, standard time, bay window, block-section.

Basic principles of façade finishing according to the proposed technology which takes into account properties of decorative layers and possibilities of their use are formulated on the basis of the results of experimental studies. Various methods of using decorative layers in panel buildings are proposed. Variants of the location of various images of volumetric elements on the façade for creating effective architectural-artistic conceptions are given. The presented technology of using decorative layers is concentrated on the enhancement of quality of an architectural-artistic image of large-panel buildings due to diversity of graphic works as well as on ensuring the efficiency of production of external wall panels and durability of facades.

Keywords: decorative layer, architectural diversity, large panel buildings, surface finish of decorative layer, flat facades, color decisions, volumetric element images, relief surface.

An algorithm of calculation of eccentrically compressed reinforced concrete elements has been developed in the program complex MathCad on the basis of a non-linear model of concrete deformation. Presented practical and theoretical investigations of columns make it possible to draw a conclusion that the use of diagrams of axial compression of concrete for calculating eccentric compressed reinforced concrete elements is possible without their transformation.

Keywords: eccentric compression, reinforced concrete, bearing capacity, deformation diagram.
