When computing Px no individual load factor need exceed 1.0; ∆ is the design story drift occurring simultaneously with Vx ; Vx is the seismic story shear force acting at story x; hsx is the story height of story x. hsx=hx – hx-1 ; Cd is the lateral deffection amplification factor given in Code for each of seismic lateral-force resisting systems; If Θ 0.1, ignore P-delta effects Doina WCTE 2006 - 9 th World Conference on Timber Engineering - Portland, OR, USA - August 6-10, 2006.

It is appreciated that the walls made from ceramic pieces are the most affected, being this more evident for the smaller and denser pieces; for its part the outer wall formed by block mortar turned out to be the most beneficial, however this benefit must be analyzed with low thermal efficiency or combined with more efficient insulation materials such as polyurethane.
