For steel beams,the flexural-torsional instability is taken in consideration by the form of lambda= (My/Mcr)^.5 being My the yelding moment and Mcr the Elastical Critical moment, with which we can obtain a reduction factor for the final plastic or elastic...

I am using SAP2000 10.0.1, but have tryed versions 10.0.7 and a beta version of SAP2000 v11...
I tried to model a very simple square slab, working as a one way slab, and so having supports only on two parallel sides
The dimensions are not relevant...
I tried 2 situations:
- simply supported...
It's often used the modelling of shear walls as frames with the properties of the real walls, sometimes aplied with a reduction factor of inercia to simulate the crack state.
If someone uses shells instead of frames to modell the same shear wall, is it possible to aply the same reduction...
When drawing section cuts for example aplied to a slab, something that at first case seemed to solve the problem of slabs, it was quite a desillusion, since the diagrams shows with the right shape, but you only have access to the integration of the total forces on the left and right sides of the...
By default when aplying insertion points in a frame to simulate diferent positions of gravity center, there is an option "Do not transform stiffness for offsets from centroid".
I'm trying to model a post-tensioned beam connected to a concrete slab (with shell element), considering equivalent...
Imagine that you have a shear wall with 0.25 x 9.00 meters, that somehow was needed with this geometry! How do I calculate the reiforcement! Is it still valid the theory that the section remain plain, and perpendicular to it's axis?
In a smaller shear wall, for example, 0.25x2.00 or 0.25x3.00...
