Efficient Fire Protection Requirements for Residential Buildings
It is shown that the main amount of fires and death of people take place in residential buildings. The efficiency of the fire-protection systems is at the level
of 50–70% that is not enough. The existing normative requirements for fire safety in residential buildings, high-rise ones especially, are imperfect mainly. It
is noted that in the codes of rules it is necessary to use some innovative solutions: the limit of fire-resistance of main bearing structures is not over 180 min.
and at the calculation-analytical substantiation; restriction of parameters of an in-built-attached part (stylobate); application of address-analogue system of fire
alarm, automatic fire-suppression unit (FSU) with forced start, water-ring reels, modular units of fire-suppression of a aggregate type at the height over 100 m,
means of salvation and self-rescue; protection of escalators with anti-smoke curtains and other engineering solutions; construction of atriums for the whole
height with systems of smoke exhaust (mechanical or natural) ventilation; smoke tight stair case of N2 and N3 types or their combination in the absence of N1.
Other solutions can be realized, if necessary, through STR (Special Technical Regulations) as a document of obligatory application which excludes the use of
other standards and codes of rules according to the part 2 of the article 5 and part 6 of the article 15 of the Federal Law on 30.12.2009, № 384-FZ “Technical
Regulations on Safety of Buildings and Structures”.
Keywords: residential buildings, fire, code of rules, fire safety, fire resistance, atrium, fire area, systems of fire alarm, automatic fire-suppression unit with
forced start, smoke tight stair cases, means of salvation.

Calculation of Bored-Injection Piles of Improved Bearing Capacity
The technology of bored-injection piles made according to the electric-discharge technology is introduced in the practice of geo-technical construction. The
existing methodology with the use of SNiP formulas doesn’t allow to fully evaluate the stress-strain state in the active zone in the course of sequential inclusions of
widenings in operation with the growth of loading on the foundation. The article presents results of calculations of the stress-strain state of the base of the boredinjection
pile ERT made with multiple widenings along the pile shaft. Calculations were made in spatial statement with due regard for stages of load application
and formation of the compacted zone around the bored-injection pile. Special attention was paid to the difference in the stress-strain state of the base composed
of cohesive and non-cohesive soils. The assessment of factors influencing on the bearing capacity and settlement of the bored-injection pile was sequentially
made. The number and pitch of widenings, the length of bored-injection pile, strength and deformation characteristics of the surrounding soil were considered as
the factor investigated.
Keywords: pile widening, bearing capacity, electric discharge technology, jet-grouting.

Interaction of a Pile-Drain with Surrounding Compacted Clay Soil
and Pilework with Due Regard for Time Factor
The problem of interaction of a pile-drain made of coarse-grained soils with the surrounding silt-loam soil is considered. It is supposed that after the preliminary
deep compaction a composite cylinder of the pile and surrounding soil is formed. This article presents an analytical solution of the task. It is shown that the settling
and bearing capacity of the composite cylinder are determined by the physical-mechanical parameters of its elements as well as geometric parameters of an
elementary cell. The solution takes into consideration elastic-plastic properties of the pile-drain, besides the rheological properties of the surrounding clay soil are
also taken into account. The solution shows that the redistribution of forces in elements of the cell takes place in time. Under the effect of the redistributed load
on the grillage in the composite soil cylinder of the sand-gravelly pile-drain and compacted clay soil the complex and heterogeneous stress-strain state occurs.
At this, the distribution and redistribution of stresses on the pilework between the pile-drain and the surrounding soil takes place in space and time. At linear
dependence of deformation properties of the pile and the surrounding soil, the distribution of stresses from the pilework occurs proportionally to their rigidity and
in accordance with the equilibrium condition. In this case, the reduced modulus of deformation of the cell is determined as a whole.
Keywords: soft clay soils, pile-drain, foundation, stress-strain state, rheology, grillage.

Theoretical Prerequisites of Evaluation of Friction Magnitude Along the Lateral Surface of «Fundex» Pile
Structural features and technological sequence of «Fundex» piles driving which influence on the change in the stress-strain state of soil are described. The main
structural feature of this type of piles is a non-constant diameter of drilling tool which drills the well with forced displacement of soil. A lose tip is pressed by the well
casing of significantly lesser diameter, as a result of this, the contact zone is formed along the lateral surface with reduced characteristics of soil. This phenomenon
is not taken into account in the existing normative document when calculating the bearing capacity. Under field conditions and processing the large amount of
tests of «Fundex» piles, authors obtained the value of bearing capacity reducing along the lateral surface. The analytical task of widening cylinders of hardening
soil was set and solved in this article with due regard for the stages of pile installation. The results obtained make it possible to determine the reducing coefficient
which the most correctly reflect the bearing capacity of «Fundex» piles under the conditions of weak claye soils. A theoretical substantiation of friction reducing
along the lateral surface of the «Fundex» pile in weak soils is proposed with due regard for structural and technological parameters and stages of pile installation.
Keywords: «Fundex» technology, off-size lose tip, shedding concreting method, pile, bearing capacity.

Results of Numerical Simulation of Joint Zones of Reinforced Concrete Slabs with Sheet and Bar Reinforcement
The article presents a calculation model and results of the calculation of strength and rigidity when pushing joint zones of reinforced concrete slabs with combined
reinforcement cages in which sheet and bar reinforcement is combined. Numerical simulation was conducted with the software complex «Nastran – Patran» using
the postprocessor which provided convergence due to the adaptive tracking algorithm of load pitch depending on the loading stage. The account of physical nonlinearity
was carried out due to the use of the modified Drucker – Prager yield criterion and the deformation model of concrete with due regard for crack formation
and dilatancy. Numerical simulation of a thick slab loaded with stamp axial load made it possible to determine the areas of volumetric compression and predestruction
due to restrained shear. In the calculation model, the special attention was paid to the contact between the sheet reinforcement and concrete which
was simulated by a special element of «glued» type. Verification of the results was provided by comparison with the data of full-scale experiment with samples of
reinforced concrete slabs with combined sheet and bar reinforcement.
Keywords: calculation model, strength and rigidity when pushing, sheet and bar reinforcement, strength criterion of concrete, deformation model of concrete,
area of volumetric compression, area of pre-destruction.

Joint of Walls and a Socle Overlapping without Heat Conductive Inclusions for Buildings with Ventilated Cellars
Numerical analysis of a fragment of the joint of wall and socle overlapping of buildings with ventilated cellars was conducted with the use of the calculation
program of three-dimensional temperature fields. Variants without heat conductive inclusions and with the masonry of small concrete blocks along the overlapping
are considered. The results of calculation show that the use of facade reinforced concrete panels significantly improves the temperature regime in the zone of
joint of structures and reduces the heat losses.
Keywords: specific heat protection characteristics, transmission heat losses, matrix method, partial heat protection characteristic, local heat protection
characteristic, energy consumption.

Seismic Protection of Settlements of Russia with Due Regard
For «Unpredictability of the Next Dangerous Natural Phenomenon»
Technical solutions for the seismic protection of settlements with due regard for the factor of «unpredictability of the next dangerous natural phenomenon» on
the planet Earth (on the example of earthquake mostly) are proposed. On the basis of the analysis of scientist-geologists that the dynamism of the planet Earth
is predefined by a number of independent energy sources, it is concluded in the article that humanity is deprived of the opportunity to determine the place, time,
and intensity of the next dangerous natural phenomenon. The factor of «unpredictability of the next dangerous natural phenomenon» (UNDNP) tacitly requires
the builders to use in the calculations for protection of settlements maximal intensities of natural phenomena only. However, there is no even recognition of the
settlements as objects of capital construction in the Federal laws and regulatory documents of the Russian Federation of a building content. Therefore, the article
substantiates the protection of settlements, the largest objects of capital construction in Russia, against dangerous natural phenomena and with due regard for
requirements of «UNDNP».
Keywords: dynamism of Earth, factor of «unpredictability of the next dangerous natural phenomenon», earthquake, protection of human life and health in buildings.
