Effective building systemsApril, 16th, on the exhibition ''Interstroyexpo" the scientific and practical conference "Effective heating, ventilation and air conditioning systems" traditionally was held by ABOK ( Russian Association of Engineers for Heating, Ventilation, Air-Conditioning, Heat Supply and Building Thermal Physics). As a central event for specialists in building systems, the conference attracts a lot of participants, also from other russian cities.

The article is an analytic review of various methods for seismic
insulation. Classification of seismic insulation systems is given. The
main design solutions are examined, their advantages and disadvantages
V.D. Kuznetsov, V.A.
The seismic insulation system using fluoroplastic
proposed. The structure is created on the base of combination of
rubber-metal bearings and dampers. The structural layout is given,
structural behavior is considered for the case of earthquake. Finite
elemnts model of building is created and calculation for progressive
fracture is conducted.
I.O. Pogrebnoy, V.D.
In the article the building technology using prestressed reinforced
concrete is analysed. Principal design models of non-nogging building
frames with prestressed reinforcement were created. Dependences between
covering thickness, concrete and reinforcement consumption and bay size
withprestressed reinforcement or witout it.
T.S. Morozova, V.D.
Coal-plastic behavior is considered with relation to concrete
structures strengthening. Four finite elements models for different
strengthening types of cast concrete columns are given. The optimal
reinforcement scheme for short columns is discovered. Dependences of
displacements on loading are received.

In the paper the influence of work joints on the thermotechnical
homogeneity of walling is estimated. Now heat resistance of walling is
often calculated from main wall material parameters. Heat-conducting
inclusions like mortar joints are not taken into account.

In the article the finite elements modelling and calculation of system
"pipeline-piles-foundation bed" for above-ground laying and beam pass.
Thermal loadings on the pipeline in permafrost are taken into account.
Simulation is made by software SOFiSTiK.

The article is dedicated to the problem of pipeline insulation.
Existing solutions are analysed and modernization of silicate enamel
pipeline covering is proposed. Suggested technology of oxyfuel gas
spraying allows to increase productivity and reduce expenses
In the article various solutions for indirect heating of private houses
are considered. The end-to-end solution is proposed with using of soil
energy and heat storages.
The author analyses responsibility of building systems designer in the
view of air influence on the human health. Processes in the organism
are modelled when carbonic gas content in the room increases. The model
and experimental data are compared.

The quality control system in construction in self-regulation is
considered. Control functions distribution between the project
participants is analysed. The author suggest a standard project
"Evaluation of quality control system in construction" for application
in self-regulated organizations.

In the article various estimate bases are analysed in historic
prospect. Classification of software for estimation and criteria for
its selection are given.
When building structures technical inspection is done, the expertise is
usually used, i.e. the expert make a decision about technical state
group on the base of certain diagnostic characters and his professional
experience. In the article the author tries to make a technical state
estimation process more strict. For that he classifies diagnostic
characters, and on the base of this classification he develops a
diagnostic matrix including diagnostic importance of each diagnostic

In the article rather new resistive electrocontact method for building
structures inspection is investigated. The influence of ambient
temperature, steel grade, specimen thickness and sensor pressing force
on the measurements is analysed.

The article is dedicated to the new integral waterproofer for concrete
on basis of mazut.
Chemical reactions between waterproofer components are analised.
Results of tests for modified concrete for strength, axial compression,
water absorption kinetics are given.
