Сultural sight objects of the central part of Donetsk city: the extent estimation of their accessibility to physically restricted people
Donbas National Academy of Civil Engineering and Architecture
Abstract. The paper is devoted to the problem research of availability of cultural sight city objects accessibility elderly for people and senile age, invalids of various medical categories (the blind, people with disordered support movable and poor sight). The authors concentrate the ablention to the essential role of given objects in the vital activity and invalids rehabilitations and also in their social contacts stimulation with the basic part of society. The paper emphasizes an importance of specific invalids on the various stages of designing, construction and operation of cultural sight objects of the city. The potential opportunities of adaptation in the new conditions of some already developed types of buildings which have not been adapted for these categories of population considered. On the basis of the location research and public opinion results, the conclusion is made as for necessity and expedience of carrying out of the range planning and constructive-and-technical activities aimed to the adaptation of these buildings types of and constructions to provide their accessibility for the given categories of population.
Key words: physically challenged people, cultural sight objects of city, the rehabilitation environment, adaptation

Active elements of building composites’ structure
Odessa State Academy of Civil Engineering and Architecture
Abstract. In this paper there have been considered the active structure elements, such as cracks and inner surfaces of partition. First of all reacting on the operating loads complex acting on the structure. The «ability» of material (stuff) to preserve certain properties on the given level depending on quantity, orientation and initial cracks and inner partition surfaces of. Such an «ability» testifies about one of the construction material (stuff) adaptation types as open system by means of parameters changing of active structure elements (self-organization). Active elements of the structure appear and develop in the material (stuff) on the stage of creation of construction as a system, what provides safe work conditions on the stage of caring out of certain functions, laid into the system. It’s very important to lay the certain combinations into the structure of material while constructions design.
Key words: building composites, structure, active elements

Theoretical basis of optimum technological decisions to stream technology of the thin-walled constructions concreting
Odessa State Academy of Civil Engineering and Architecture
Abstract. The theoretical basis of the stream concreting technology with using of elastic throwing devices is the new naturally scientific essence of mechanical, physical and chemical processes which are the basis of the tough fine-grained concrete mixture transformation in the especially dense high durable concrete of the thin-walled constructions. With researches getting of high-dense fine-grained concretes of the thin-walled constructions in the conditions of construction site, it has been established that most effective solution is the methods of the stream concreting technology, while realization of which the concrete mixture, being regenerated to the discrete particles flow, is densed under act of very intensive inertial forces action. Recently technical means technology of concreting were used mainly pneumatic apparatus: cement-cannon and injector machines. But in connection with considerable power capacity, complication and metal capacity of technological equipment, the pneumatic methods of stream technology as before are used restrictedly. The situation changed in the interest of stream concreting technology, when for getting of dense concrete for building constructions the method of rotary condensation, while which concrete packing with condensation was carried out by means rotors which were revolving with the certain speed.

Operating peculiarities of industrial buildings steel frames in conditions of unequal deformation of precipitional basement
Zaporizhzhya State Engineering Academy
Abstract. The operation problems and inspection results of building structures built on the soil with high level of subsidence were examined by example of JSC “Zaporozhtransformator” assembly building №1 are considered. The building was designed in the middle of the last century on the small foundations, which are based on the considerable thickness of loess-like claysy and sand soils related to the II class of subsidence soils. It has been determined exactly unequal base subsidence caused the cracks arising in the walls, disturbance of gantry rails horizontality, additional efforts and damages in the trussing girders. The other factors are analyzed influencing one the structures efficiency among which play the important part, mistakes while building design and structures assembling. The building efficiency is provided with observing system of the damages, thorough stressed state analysis, well timed strengthening of disabled and overloaded constructions.

Research of the packed zone parameters of the soil mass if while its strengthening by condensing pressure
Donbas National Academy of Civil Engineering and Architecture
Abstract. The presumable scope of strengthening method of the basements by condensing pressures and conditions necessary for its application is considered. Zones with the PDC corresponding to various models design of the ground are described. Results of experimental researches have been given: changes of diameter widening and the condensed zone from size of condensing pressure, the factor dependence porosity in the zones limited with considered points of a soil massif, and pressure. And also the analysis of experimental researches has been carried out.
Key words: strengthening the basement, condensing pressure

Results of stability monitiring of the fixed landship dangerous slope, located in Yourevka settlement, Donetsk region
Donbas National Academy of Civil Engineering and Architecture
Abstract. Results of monitoring restraining structures on the territory “Locomotive”, located in Yourevka of Donetsk Region, witch took place in April, 2009 have been presented. Also conclusions concerning stability landslip slope have been given. Actuality of the problem the Sea of Azov (Donetsk Region) shoreline slopes.The reasons of the landship process in this region have been considered. The results of gation in Yourievka settlement and the state of restrained structures. And drainage system state have been suggested as complex measures to provide the given slope steadiness. Recommendations for the further operation against landslip combined structures have been given. The reasons of incorrect work of drainage system have been exposed and recommendations for their elimination have been given.
Key words: restraining structures, landslip, slope, stability.
