    Two components of impact toughness, namely a work of initiation a and a work of propagation ap of ductile crack, were determined using 4 melts of flat (32 sheets) 60 mm thick and 2 melts (2 sheets) 17 mm thick made from 16G2AF steel. The influence of structure parameters (a size of ferrite grain, fraction of pearlite, amount of sulphides) and hardness on the values a and ap has been considered, and on this basis the possibility of determining a founded normalizable value of impact toughness controlling the quality of steel has been analyzed.
    Key words: impact toughness, work of initiation, work of propagation, normalization, high-strength steel 16G2AF, structure.

  • Experience in Three-Dimensional Modeling of Multi-Core Reinforced Concrete Floor Slabs for Solving the Nonstandard Problem
  • UDC 624.012.3/.4 + 624.04
    Lidiya P. ABASHEVA, Igor L. TONKOV, Yuri L. TONKOV
    The experience in three-dimensional modeling in the "SCAD" environment of multi-core reinforced concrete floor slabs of a real building for calculation of deflections caused by asymmetric load is expounded. The description of the actual design of slabs in different versions and their computer models is made. Results of the calculation and their practical significance are considered.
    Key words: three-dimensional model of reinforced concrete slab, unevenness of cross-sectional stiffness, vertical displacement.

  • Numerical Analysis of Stressed-Strained State of a Nodal Joint of Glued Wooden Arches with Steel Cylindrical Dowels
  • UDC 624.03
    Aleksandra J. ZOBACHEVA
    The stressed-strained state of a ridge nodal joint of a large span wooden arch with steel cylindrical dowels is analyzed using the method of numerical simulation with due regard for timber orthotropic properties and the frictional forces of timber-metal surfaces. The influence of the joint's parameters on the character of distribution of stresses and strains in elements of the node structure is studied on the basis of the mathematical theory of optimal planning of the experiment.
    Key words: long-span glued wooden arch, numerical investigations, stressed-strained state, nodal joint, mathematical theory of experiment planning.
