The dependence of influence of size of a bend on tensely strained state of load-bearing frames of a covering is analysed. On the basis of the received results the maximum corner of a bend of the metal corners reducing a carrying capacity of farms is defined.
Keywords: a rafter farm, bend, tensely strained state, a moment of inertia, a radius of gyration, a barycentre
This article analyzes the stress-strain state of exploited reinforced concrete crane beams in order to identify the causes of abnormal damages. Also, the degree of influence of the revealed damages on safety and operational fitness was assessed.
Keywords: crane beam, technical condition, operational availability, defect, durability, damage, inspection, discretization, stress-strain state
This article discusses a comparative analysis of the results of calculations of a building erected on an unevenly deformable base. The authors, taking into account the peculiarities of the engineering-geological conditions of the territory of the city of Volgograd, made a verification assessment of the influence of the heterogeneity of the bedding coefficient of the soil foundation on the VAT of the structural elements of the building when calculating the final draft.
Keywords: bulk soils, foundations, bases, bed ratio, backfilling, compliance, stiffness diaphragm, stress-strain state
