Computational modelling of random distribution of  stresses for wooden structures

Stochastic allocation is the main characteristic of processes which can be described in wooden structures. Random distribution of stresses and deformations in such structures is mostly based on timber imperfections, such as different curvature of sticks, presence of knots, twigs and gnarls.

Lifetime of earth dams

The level of safety of small earth dams, operating without staff and measurement and control equipment, are considered in this study. Approach enabling the possibility to define the finite lifetime (Tf) of a small earth dam here presented. The proposed approach does not require any variables monitoring.

Stress-strain state and performance of a high rockfill dam with a grout curtain

This paper examines the results of numerical simulation of the stress-strain state (SSS) in a rockfill dam 235 m tall, with a massive three-tier grout curtain used as the impervious element. Calculations were done for multiple scenarios that reflected the wide range of possible changes of the modulus of deformation for the filler rock and cemented soil (200 MPa to 5000 MPa).

Deformation of concrete creep in the thermal stress state calculation of massive concrete and
reinforced concrete structures

In the article the thermal stress state of the reinforced concrete foundation of a nuclear power plant during the building period are analyzed. The calculation results of thermal stressed state in massive foundation slabs with and without concrete creep is given. The article also provides a comparative selection of insulation to ensure crack resistance of the foundation plate with and without creep.

Design features of facade cassettes from thin ceramics

Thin ceramic plates are a promising material for architectural use which has significant potential for the realization of different interior and exterior solutions. The use of thin ceramics as facade cladding requires increased attention to the stress-strain state and the nature of its destruction.
