PRACTICAL CALCULATION OF FLEXIBLE MEMBERS WITH THE USE OF NON-LINEAR DEFORMATION MODEL AS EXEMPLIFIED BY TYPICAL GIRDER RGD 4.56-90

Abstract

The article is devoted to practical calculation of strength of flexible members made on the basis of non-linear deformation model taking into account experimental diagrams of materials deformation. The relative deformations are determined in the proposed calculation depending on maximum flexion of a member. The calculation of maximum flexion of a member will be performed using two iteration methods. The basic calculation formula, original block diagrams of methods and comparison of calculation parameters proceeding from results of practical calculations made as exemplified by typical girder are provided.
