Explored
orthotropic shallow shells of double curvature, as well as cylindrical
panels that are reinforced from the concave side by an orthogonal grid
of stiffeners. The external transverse load acting on the structure is
uniformly distributed and has a linear dependency on time.

The
current study investigated the variability of the main parameters of
drifting level ice during ice season and how this variability affects
the ice load. The study was carried out on the example of hydraulic
protective structures of the floating nuclear thermal power plant in
the city of Pevek.

In
the paper, it is proposed to use synthesized amorphous aluminosilicates
as a modifying supplement in cement adhesive dry mixes. The results of
the analysis of the chemical composition and microstructure of the
developed supplement based on amorphous aluminosilicates used as a
modifying supplement in the recipe of adhesive dry mixes are given.

Practically
all sources of fresh water suitable for agriculture, water supply to
the population and vacationists, as well as for industrial development
on the Black Sea coast of the Caucasus either have completely exhausted
themselves or are on the verge of their possibilities. Further
development of the region is directly related to the resolution of this
problem.

As
mass irregular structures are more influencing on the behavior of the
structures, it is investigated the effect of these irregularities
according to the probabilistic approach. Comparison of seismic
performance of ten regular and irregular 6story concrete special
moment frame is done, based on the Mean Annual Frequency (MAF) method.

The
results of the study of the effect of the main properties of mineral
fillers from cement stone with different degrees of hydration, phase
composition and pore volume characteristics on the properties of the
bitumenmineral binder are presented. Dependencies of the influence of
mineral filler on the basis of cement stone on the basic parameter of
the structure of bitumenmineral bindersthe thickness of the
adsorptionsolvate layer of bitumen, which was established using the
rheological method.

The
settlement of foundation is one of the main existing problems which
face construction engineers during the construction operation processes
since the design of a project and through the whole construction life
and it leads to bad consequences on the construction. Many methods have
been implemented during the last decades to stabilize the soil, lift
basements and reduce further settlements.

We
study the natural oscillations of a rectangular plate, two adjacent
edges of which are clamped, and the other two are free (CCFFplate), as
an element of many building structures. The deflection function is
chosen as a sum of two hyperbolic trigonometric series. Both series
obey the main equation of free vibration.

The
behavior of Prussian vaults of brick aggregate concrete differs both
from the behavior of brick vaults and classical flat slabs. Such vaults
are particularly susceptible to physical damage and deterioration. To
determine the real bearing capacity of the vaults, the authors not only
performed the insitu determination on several sections with deflection
control, but also numerical simulations of the multispan system of
Prussian vaults in the program complex Abaqus.

Lightweight
steel concrete structures (LSCS) constitute an innovative building
structure type that can be used both for loadbearing and enclosing
purposes. They consist of steel profile – usually galvanized and
coldbent – filled with a monolithic foam concrete with 200 kg/m3 and
more density value, and with fiber cement panel sheathing.

Isotropic
viscoelastic plates of variable thickness under the effect of a
uniformly distributed vibration load applied along one of the parallel
sides, resulting in parametric resonance (with certain combinations of
eigenfrequencies of vibration and excitation forces) are considered in
the paper. It is believed that under the effect of this load, the
plates undergo the displacements (in particular, deflections)
commensurate with their thickness.

A
rod model of a statically determinate planar frame with four supports
is proposed. The task is to obtain an analytical dependence of the
deflection of the truss under the action of various loads on the number
of panels in the crossbar and in vertical support trusses. To solve the
problem, the computer mathematics system Maple is used.

Recently,
variety of largescale constructions from monolithic concrete
structures have been built in different regions of Vietnam. The
application fields of these structures are extensive including the
marine construction, underground structures, the highrise building
erection and others.

The
concentrically braced system is one of the most common lateral load
bearing systems among steel structures. These systems have remarkable
lateral stiffness and strength, but their compressive buckling prevents
them from being ductile and absorbing optimal energy.

The
overall objective of this article is to study the potential of the
reagent treatment of wastewater resulting from the iron ore
beneficiation process, as well as preventing the discharge of the
wastewater into the open waters. The wastewater at the Mikhailovskii
iron ore beneficiation plant (Kursk Region, Russia) discharged into a
tailings pond has become an object of the research.

Finite element models for plate bending
problems are constructed on the basis of approximations of moments
fields. The bending and twisting moments are approximated in the finite
element area by piecewise constant functions. The solution is based on
the functional of the additional energy.

Improving
the efficiency of construction composites is a relevant problem for
modernday material science. One of the ways to solve the problem
consists in activating the binders by means of vortexlayer devices.
Mathematical transformations produced a formula for calculating the
dependency of the number of ferromagneticparticle collision on the
number and velocity of such particles, as well as on the device chamber
fill factor.

The
research is targeting at multilevel overpasses which offer one of the
solutions for laying the highway in conditions of dense residential
development and close proximity to bedroom communities. In terms of
acoustics, multilevel overpasses are semienclosed structures made of
metal and reinforced concrete, where a complex sound field with
numerous rereflections is formed.
