3D stress and torsion



SCIA Engineer 16 is coming with improved calculation of shear stress. This improvement influences the results if the load is not applied in the shear centre but in the centroid. For uniaxial symmetric cross-sections (mostly steel sections C,U) the position of the shear centre differs from the location of the centroid and this eccentricity causes additional torsional moment. It influences the value of the shear stress. Therefore, it is important to pay attention to this issue.

The effect of the eccentricity has been correctly taken into account in steel checks but the user had not chance to see this effect in 3D stress results. Therefore, this new feature has been implemented and it is now possible to check this effect also in the basic result service.
