Problems of compressed elements

Abstract

The elements loaded with longitudinal force are pillars, walls and rods. They are compressed and tensile stressed. The force acting on them can be centric or eccentric. Compressive stressed elements can be slender or not. For slender elements (λ>25) there is a risk of deflection, while this danger with short elements (λ<25) does not exist. Due to the risk of deflection in the calculation of the required reinforcements applied a coefficient k, in the range from 0.250 to 1.0, which is depends on the element slenderness ratio and the eccentricity of the force. The slenderness length depends on the boundary conditions.
