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.

Purpose: The main purpose of the article is to identify the place of the information technology in the modern world and the importance of developing the IT center architecture through the study of foreign and domestic analogues. The article presents information about the modern trends in architecture of information technology centers.Design: The article describes the main solutions for the place of IT centers in the urban environment and their functional and architectural planning features.Practical implications: The information technology potential is identified, which is being rapidly developed. The constant growth of Internet users creates an increased demand for various information products. The emergence of IT centers not only allows realizing the regional potential, but also forming a social infrastructure and a comfortable urban environment.Originality/value: One of the main tasks solved by an architect when designing an information technology center is to take into account the peculiarities of intellectual labor and create appropriate conditions for employees. This is realized through the use of "flexible offices" and a large percentage of recreational areas for workers. One of the important characteristics of the modern information technology center is its compliance with the green architecture, which implies concern for the environment and use of alternative energy sources.

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.

It is proposed to use the promising digital image correlation method based on laser speckle imaging and high-speed video recording during bridge testing. The analysis is given to test results of the bridge over the Burunduk River in the Tomsk region and its dynamic characteristics using the Faza-1T measuring system. Relative displacements of railway beam surface are determined under live loads when using digital image correlation. According to the analysis the experimental data, the digital image correlation method and described equipment are efficient for using them in sites.

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.
