Stability coefficient

Θ = \frac{P_{x} \cdot Δ \cdot I_{e}}{V_{x} \cdot h_{sx} \cdot C_{d}}

Θ	Stability coefficient
P_x	Maximum design vertical load on and above story x
Δ	Design deformation of the story defined in Chapter 12.8.6
l_e	Importance factor according to 11.5.1
V_x	Horizontal shear between floors x and x - 1
h_sx	Story height below the considered story x
C_d	Deformation amplification factor according to Table 12.2-1
