the current state and experience of foreign researches of
cross-laminated wood as products for the construction industry are analyzed.
The basic principles of production of CLT
material and its design features, as well as the advantages of CLT structures
in comparison with traditional structural materials are given. The reasons
limiting the use of this material in the Russian Federation are indicated. The
results of research work are presented, the purpose of which was to study the
strength and elastic characteristics of a new structural material made of CLT
by conducting experimental studies to determine the bearing capacity of
structures made of CLT, as well as the development of modern standard test
methods for determining the bearing capacity of structures made of CLT, as a
bimodular orthotropic material. Information is provided on the test methodology
used and the results of experimental studies to determine the floor slabs bearing
capacity in bending out of the plane of the sheet; wall panels load-bearing
capacity in compression in the plane of the sheet and determination of the wall
panels rigidity in shear in the plane of
the sheet for samples with different grades of wood, the number and layuot of
outer layers. The data of experimental tests of CLT samples to determine the floor
slabs bearing capacity for bending and wall panels for compression and their
rigidity in compression are presented, the nature of deformation and
destruction depending on the design features of the CLT material is studied.
The prospects for using the results of the work in the development of normative-technical
and organizational-methodical documents are determined.
