Long-span roofs have been of an increased interest within the last sixty years. An archtype
steel roof of velodrome with the maximum span, height, and length equal to 109.50, 23.07, and
126.00 m respectively, is considered as the object of the current investigation.

Using suspended structures in construction is one of the methods to improve the
earthquake buildings resistance. This subject became very popular in the 60–70s of the 20th century.
However, at that time there were no available methods to provide full studies devoted to the buildings of
this type. Soon, however, the opportunity appeared due to the development of computer engineering.
This caused further analysis and disclosure of the full potential of suspension systems.

Modern structures require more complex designs. There is an increased need for
accurate approaches to assessing uncertainties in loads, geometry, material properties, and operational
environments. However, information is scarce on the reliability of suspension roofs together with their
joints. There is an urgent need for estimating stress-strain state and reliability of welded joints, so
recommendations can be given based on the obtained data.
Nowadays, the standard techniques of backing the ballasted pipeline laid in a bottom
trench are used: sequential deposition of soil by suction dredges along the slurry pipeline, soil discharge
by self-dumping barges, soil unloading from a barge by the grapple, soil pumping from barges. The
disadvantage of these methods is that backfill is done in consecutive stages, and soil, falling into water
increases water specific weight to the pulp specific weight.

The strength properties of wood have a great variability within the same species and the
same growing region. In this regard, defect parameters do not fully characterize the strength and
deformability of structural timber. Deterioration of timber quality requires a more reasonable use of
resources and accurate assessment of the strength properties of output timber.
