Did you ever meet the requirement to design shear walls? Or have you created a shell model of a bridge and you need to change it to 1D model due to the other calculations? We have solution for you in newly released version of SCIA Engineer 19. We have developed functionality called Integration member which can help you with this. Integration member integrates all internal forces from 2D as well as 1D members which are in the defined bounding box around the member. This results in internal forces of 1D element. You may assume that it would be pretty difficult to define and use this integration member. That's not true. You just need to define the axis of the member, type and size of the bounding box and press the button. You don't need to define any master slab as in the past because the integration member is an independent entity and does not influence the rest of the model nor the analysis part. The whole calculation is done on the background once you ask SCIA Engineer to give you internal forces for any load case, combination, result class. The integration member works for linear as well as non-linear analysis.
Introduced in version 19.0
