IJR,
There is a simple way in stick modelling. Lste consider a l-shaped shear wall (you can take this analogy & extend to any shape).
Lets consider a L-shape with points a,b & c, with b being the intersection of the walls. so you assign 3 columns, 1 each at a,b & c. calculate the properties of...
Normally the shear capacity is dependant on the longitudinal tension steel, the more the tension steel, the more is the shear capacity of the beam. And we have to provide shear stirrups for the balance of (shear force-shear capacity for provided tension steel).
But if the shear stress exceeds...
If you are considering that the slab/diaphragm offers resistance to torsion in beams, then you should check that wether that slab can resist that much amount of additional moment (that is being transferred to it because of torsion). The safest way is to design the beam for the torsion, rather...
