The algorithm of calculation of the main geometrical characteristics of the section consisting of pair angles at a bend of both angles is made. The received results are applied to definition of a carrying capacity of an element of a farm.
Keywords: a rafter farm, bend, a barycentre, a moment of inertia, a radius of inertia
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.
