In Tekla Structural Designer 2020 new 2D stress contours are added to the existing options giving the in-plane stresses in 2D element meshes.
The in-plane stress is in effect the average stress through the thickness of the element, which we think will be of greater interest to more engineers especially those wanting to assess the extent of cracking in concrete walls. For this purpose the (vertical) “σy in-plane tension” result will be of most use.
This will be the case especially when the engineer creates envelopes, which will make it very easy to see panels with zero tension (which could then be set to uncracked).
This feature goes together with the New Review-View Control of Cracked/Uncracked Setting for Concrete Members to facilitate more rapid assessment and control of the appropriate analysis properties to use for concrete buildings. The user can have two side-by-side views open to simultaneously review the stress contour results via one and review/edit the Assume cracked setting via the other.
