10D. DIMENSIONING PART 4/4

CHAPTER 10D 'DIMENSIONING' 24 • Proficiency checks are carried out at the level of the pile/support cross-section and in terms of forces and deformations , depending on the Performance Level. • The following quantities are calculated: N : Axial compressive load of a pile or lintel (vertical for pile, horizontal for lintels), after integration of the corresponding normal stresses (σxx,σyy) of the surface finite elements forming the control section. M : Cross-sectional force is calculated by integrating over all finite elements the product of the compressive axial force of each element on the lever arm between the centroid of the element and the centre of the cross-section. H0 : Distance between the cross-section in which the bending capacity is achieved and the point of zero moment. It is determined by the eccentricities at the base and top of the wall. In the case where both ends are buttressed H0=H/2. In the case where the eccentricities are homopolar, a limit H0≤2·H has been adopted. D' : Breaking length of control cross-section. The value depends on the eccentricity of the compressive axial load ( e=M/N ): • e≤ D/6 , then D'=D ,
