The article proposes some innovative technical solutions to build a multistory substructure for residential and public buildings. To erect a building, it is proposed to construct a system of interconnected rail runways at a first storey level along which travelling gantry cranes and special platforms will move. To descend the machines, building materials, instruments to the design level, during the underground space development, it is proposed to employ travelling gantry cranes. In order to quickly relocate loads and machines from one work zone to another, an additional system of rails is mounted along which special platforms are moving. The management of the gantry cranes and special platforms movement is done by the remote operating panels. The superstructure is built in the traditional way using a tower crane, track mounted, for example. The application of the proposed designs when building multistory substructures will enable to improve the technological processes of building the substructures. The proposed technology will help to use it in all the climatic areas of our country.

the design of a new object presupposes not only the functional aspect, but an important factor is the location of the building or structure. The choice of location is one of the fundamental criteria: it is necessary to take into account the infrastructure and architectural appearance of the selected area, the needs of the district or region in the projected facility.

The main purpose of walls and mineral plaster, decorative finishing of external walls, but also to protect the walls from constant exposure to atmospheric agents. In addition to low water absorption exterior stucco needs to have adhesion to various bases, good vydyhaemoy and resistance to cracking. The most effective way to improve the properties of facade plasters is the introduction of hydrophobic redispersible powders which reduce the water absorption of plasters improve their adhesion to the substrate and water vapor permeability

The frequency divider for 32, operating in a range of frequencies 8-18 GHz is considered. The specifics of the schematic diagram is shown. The design and element base is described in short. The model is made and its experimental research is carried out. The technique and the block diagram of the experiment is described. Level of harmonics of an output signal is measured. For decrease of level of harmonics of the useful signal the low-pass filter of type SALF-580 is used. Presence of a parasitic output signal in the absence of an input signal is revelead.

The article is devoted to the problem of determining the air flow through cracks in the enclosing structures using numerical methods. Based on the study of the data obtained during the visual inspection, it was found that most of the apartment buildings have significant physical wear, which is mainly characterized by the presence of cracks. Particular attention is paid to the assumptions made for the design scheme. On the basis of the equations of dynamics and continuity, a mathematical model is obtained that allows one to predict the airflow through the crack

The transverse vibrations of the beams of a constant cross section are taken into account, taking into account the damping. We consider random oscillations of a beam under the action of vector kinematic and dynamic effects. The examples show the influence of correlation coefficients on the standard deviations of the cross sections of a beam. The internal forces in the form of bending moments and transverse forces are determined. An example of an action of a random process with a latent periodicity is given

Discusses actual problems of determination of the resistance and protection of concrete structures – slabs, produced by standart adopted in the Russian Federation and the United States. Studied national and international experience of evaluation and quality control, measures to preserve the integrity and stability of structures to various types of exposure. The focus is on those conclusions that must be made from the analysis of the causes of destruction in order to avoid future repetition of mistakes and miscalculations that are allowed currently in the design and construction of engineering structures and which often lead to the occurrence of accidents.

The aim of this work is to study the degree of protection of underground waters of the Kuibyshev district of Rostov region. The study area represented by the geological deposits of Quaternary (recent sediments) Qh, Neogene and Paleogene systems (Oligocene) P3, Cretaceous (upper division) K2 and the Carboniferous system (upper, middle and lower portions) S1,2,3 based. On the analysis of geological structure of water-bearing rocks in the Kuibyshev district of the Rostov region, which showed an insufficient degree of protection of underground waters against pollution and, as a consequence, insufficient supply of public drinking water, built map of underground waters protection of the Kuibyshev district of the Rostov region
