The existing regulatory framework and imperfect calculation methods hinder the widespread use of pipe-concrete structures, which have great potential for industrial and civil facilities requiring small cross-sections of load-bearing elements. In order to solve this problem, a series of experiments is conducted to study the behavior of various combinations of steel and concrete materials under static load. Stress-strain state of composite and pipeconcrete structures is investigated. The analysis is given to the bearing capacity of test specimens. The critical load of specimen fracture is calculated, the bearing capacity loss and fracture are determined, deformation diagrams are suggested herein. The comparative analysis of bearing capacity of test specimens is conducted.
The analysis of experimental investigations shows the non-linear increase of bearing capacity during the joint operation of steel shell and reinforced concrete core of the pipe-concrete element, and advantages of pipe-concrete structures over conventional structures.

Cast-in-place structure design distinguish them from reinforced concrete structures. Cast-in-place structures are involved in deformation and receive external load, so they possess different strength, deformation and other physical properties. In this regard, calculation methods of cast-in-place structures given in regulatory documents require clarification.
Having studied the cast-in-place structure design and considering their stress-strain state, a method is proposed for the analysis of such structures according to their service limit state. This method allows taking into account different times of involvement in the external load and deformation of the cast-in-place structure as well as the difference in concrete strength and deformation properties. It is shown that the experimental data are in satisfactory agreement with theoretical calculations.

 Glass foam material is investigated in this paper. Glass foam materials are known long ago, but modern methods make it possible to study and scientifically substantiate their classification as nature-like. X-ray and acoustic methods are used as the most appropriate for nature-like materials. The velocity of Rayleigh surface waves and the integral intensity of the X-ray halo reflection are measured. The data normalization is proposed for comparison of measured values of speed and intensity. It is shown that the density of  glass foam materials determines the uniform distribution of the electron  density. A conclusion is made about the uniform density of amorphous  materials and their similarity to natural.

Existing test methods for thermal and hydraulic losses do not take into account the possibility of using modern instrumentation.

Choosing the optimum tool shape for soil cutting is an urgent task for shaftsinking and tunnelling as well as in soil treatment for agriculture. The roadhead shape at the available load determines the stress-strain state of soil and development depth in the bottomhole area. By changing the roadhead contour, the penetration efficiency can be increased, while the feed force and tool wear can be reduced.
Purpose: The aim of the work is to create the roadhead calculation algorithm and determine the stress-strain state of soil near it with a minimum number of boundary conditions, no discretization of the entire region into elements and approximation between nodes.
Design/methodology: Test tasks for the proposed methodology for the roadhead and the bottom-hole area. The numerical model of the boundary conditions is based on the integral formulation of the Kelvin elasticity theory problem and uses the potential method as fictitious loads and discontinuous displacements, that makes it possible to minimize the problem with regard to symmetry, obtain a more compact system of equations and give accurate solutions at any domain point.
Research findings: The assessment of the stress state of the roadhead of various shape and the bottom-hole zone of soil; loss of soil strength calculated according to the Mohr–Coulomb theory.
Originality/value: The proposed method for solving the boundary value problem is recommended as an express method for estimating the roadhead stress state of an arbitrary shape in infinite regions with regard to the symmetry and implementation in Excel.
