The problems of experimental and theoretical research on the stressed
and deformed state of steel structures under emergency actions are
particularly relevant. ̉his paper proposes experimental and theoretical
research methodology, which is used on the basis of an example of
research on a full-length truss as part of the frame for an industrial

The article reviews
the research results of influence of a complex modifying agent on
rheological properties of cement-water paste and cement stone strength.
The article describes the processes of hydration and structure
formation of cement stone, the special aspects of the phase
constitution of Portland cement hydration products in the process of
modifying by complex admixture.
frameworks are widely used construction of multistory buildings for
different purposes. In the practical framework calculations, the
girder-column joint connections are taken as either absolutely rigid or
hinged ones. The analysis of the actual behaviour of the frame joint
connections shows that they normally occupy an intermediate position in
the joints classification into "rigid" and "hinged" ones, i.e. they
have certain pliability.

facade is a contemporary facade system that is popular due to its
energy efficiency. There are different configurations of the
façade systems, among other things, various spacing between

object of the given research is the thermotechnical characteristics of
buildings. The problem of thermotechnical indicators measurement arises
at the acceptance of the buildings in use and also while performing
work on energy classification of buildings in use.

authors have estimated the effect of advanced superplasticizers of
types Muraplast, Reamin, Weiss SM, Polyplast SP-1 and Melflux on
radiation changes in Portland cement stone and concretes of radiation
protection, based on experimental data from available literature, about
the effect of such superplasticizers on thermal changes of Portland
cement stone and the known analogy between thermal and radiation
changes in Portland cement stone exposed to neutrons.

composite structural members are increasingly used in the case of
restoration of wooden ceilings. In the other hand, their use also
increases in the case of new buildings. Design methods of the composite
structures have been evolving since their first use.

are considered of systematic study of stress-strain state (SSS) of a
seepage-control wall arranged in the embankment dam foundation. The
following factors affecting the wall SSS were studied: the wall depth,
deformation modulus of the wall material, the pattern of the wall
resting. Studies were conducted with the aid of numerical modeling.
