Additional Results to the Structural Analysis of Eccentrically Compressed Cross-Section Made of no Tension Material

The mechanical behaviour of eccentrically compressed stocky bars of rectangular cross section, having no-tension material is well known. The aim of the structural analysis is to determine the distribution of the stresses arisen from the effect of an eccentrically compressive force, i.e. to describe the shape of the stress block, and to calculate the compressive resistance of the bar. Some important details of the phenomenon could not be found in the technical literature. In our paper we study these details. We evaluate the analytical functions of the curves, bounding areas lain around the kern or the point of gravity, on which areas the eccentric force acts a pentagonal compressed zone arisen. Furthermore, we determine the resistance of the stocky bar in the cases of triangular and rectangular compressive zone.
