  • Investigation of the effect of the ratio of the rigidity of the structural system to the dynamic parameters of a multi-storey building depending on the seismicity of the platform

    The results of a computational experiment performed in the Lira-SAPR environment are considered in the article. The purpose of the experiment is modal analysis of various structural schemes of multi-storey reinforced concrete frame under pulsating and seismic influences. The considered design schemes differ in the ratio of the frame and diaphragm components of the frame. It was calculated three series of samples, differing by the ratio of rigidity. The stiffness ratio varied from 20% to 65.9%. Within each series calculations were performed for seismicity of 7, 8 and 9 points. For each variant of seismicity, the soils of the 1st, 2nd and 3rd seismicity categories were considered. It is established that when the role of the frame part increases, the distribution of the modal masses shifts towards the lower forms of oscillations, and the numerical values of their frequencies decrease. Accelerations of the nodes of the coating from the ratio of rigidity do not depend. They increase with increasing seismicity of the site. The ratio of stiffness affects the total consumption of the reinforcement of slabs. This influence is significant in the range of values of the ratio from 20.5% to 42.5%. Further increase in the ratio of stiffness to the consumption of reinforcement influences slightly.

    Abstract: preventing the formation of ice on roofs and gutters of buildings appears to be socially and economically significant goal, requiring efficient and effective decision-making. Roof and gutters heating has the potential to avert the loss of life and vehicles damage due to falling icicles. The costly package of measures of manual cleaning of roofs, which often leads to unscheduled repairs of roof , gutters and facades of buildings is thus not needed. A competent choice of the way of heating is able to provide positive social and economic benefits for the city and must be done according to the availability of specific types of energy resources ...

  • Geometric characteristics of thin-walled elements of the C-shaped cross section

    The material of the C-profiles in question, manufactured by the continuous rolling method, is galvanized steel up to 3.0 mm thick. Thin-walledness and the shape of the cross-section, causes a number of features of the profiles under load. The valid design norms in addition to the basic geometric parameters of the cross-sections used in calculating the longitudinal and bending forces (A is the cross-sectional area, Sx, Sv are the static moments of the section, Ix, Iv, Ixy are the axial and centrifugal moments of inertia) , Suggest the use of sector-specific characteristics. These characteristics are peculiar only to thin-walled rods and are determined on the basis of the notion of a sectorial area. The problem of determining the geometric characteristics of a thin-walled C-shaped profile is considered. The center of the bending is taken to be the point with respect to which the moment from the tangential forces arising during transverse bending or torsion in the cross section is zero. The position of the bending center does not depend on the forces acting on the rod, but depends only on the shape and dimensions of the cross-section of the thin-walled rod.
