  • Influence of observance of the frame dome-shaped roofs assembly design technology on the quality of the completed object and its service properties

    The article examines the influence of observance of the frame dome-shaped roofs assembly technology on the quality of the completed object. This theme is relevant enough, as the building roofs, constructed in accordance with the aforementioned technology, are often found in modern business clusters. It`s natural that prospective investors are interested in perfect quality and seamless service properties of similar construction object designs. The authors considered features of the frame dome-shaped designs construction and assigned its pros and cons; the review of the technical investigation of one of the shopping centers was conducted with purpose of showing the consequences of inaccurate observance of the specified designs installation technology. Subject to facility technical investigation results, recommendations for the safety operation of dome support structures were given.

    Keywords: steel designs, frame dome-shaped objects, frame dome-shaped roofs installation, technical investigation of frame dome-shaped roofs, spherical sheath imperfections

  • Studies of the average density and porosity of sulfur composite materials on quartz filler

    The parameters of the structure of the building material, including sulfur, depend on a large number of prescription and technological factors. This paper presents the experimental dependences of the average density and porosity of the sulfur composite material on the volume degree of filling, the specific surface of the filler, the concentration of the appret and the time of isothermal exposure. It is established that the dense sulfur composites obtained with silica filler with a specific surface area of 180 m2/kg, processed 30%-and 50%-s ' solution of rubber and subjected to isothermal aging for 2...3 hours

    Keywords: Sulfur, silica filler size, filler, volumetric filling degree, average density, porosity, dispersion

  • Finite element analysis of the applicability of the applied theories of calculation of piezoelectric device of energy storage of stack configuration

    This paper considers basic element of device of energy storage which is a piezoelectric generator (PEG) of cylindrical form with the attached inertial mass. A finite element modeling of the device operation is carried out during active load in the external circuit. The main purpose of the operation is to compare the output potential and frequency characteristics of the device known in the literature models of systems with concentrated parameters. On the basis of these models, we can receive the analytical dependence of parameters of PEG with its geometric characteristics and mechanical properties of the used materials. However, the question of the range of applicability of these formulas is still open. In this paper, based on the numerical analysis of finite element models of PEG in package ANSYS, we obtained comparison with the analytical formulas that show the values of some parameters of simplified models and set the boundaries of their applicability.
