Torsion resistance of concrete shearwall core
Torsion resistance of concrete shearwall core
(OP)
Dear structural engineers,
What is your way to design the torsion resistance of concrete section (L, C, T and shaft elevetor)?
Thanks

Step one is design for bending flexure.
Step two is design for shear force.
Step three is design longitudinal bars for torsion.
Step four is design for shear torsion.
(This process is clear on codes)
For main member for more than 6 stories on seismic areas just follow Dik advise for non seismic areas you can go up to eight may be 10 stories, for auxiliary members well you have to go and design.
Nevertheless when you follow the design process and the beam is over reinforced you must stop and think it over.

You have misunderstood the question. The OP asked about design of shear cores which are eccentric, and your answer is for design of individual beam elements.
Poul75,
Big topic. After you study it and have some specific queries, come back with them.

Why is that?

If anybody ever comes across anything, please post it.

'Coupled' shear walls and symmetric cores are the easiest... for flexure, shear and torsional shear...
