At acting of two-component accelerogram “Tbilisi” the common picture of normal and tangent strength distribution in diaphragm is not distinguished from one, obtained on the basis of calculation considering two-component accelerogram “Oni”, though in this case the maximum values of indicated strength’s were decreased by 10-15 % in the mean. The mode of deformation of diaphragm, corresponding to two-component accelerogram of “Oni” that more danger for diaphragm, can be characterized by seismic loading that 2.2 times less, than the loading on the same diaphragm, deforming absolutely linear, but it 1,8 times greater than design seismic loading. In this case the coefficient of plasticity ? =2.28 and the normative coefficient K1 that takes into consideration the capacity of structure to develop nonlinear deformations, is equal to 0.43. It must be noted that increasing of real loadings 1.8 times comparatively to normative ones causes the crack development as in horizontal, as in vertical joints and in supporting cross-sections of spandrel beams along the height of diaphragm. There has been shown that the building reliability greater than the limit acceptable value 0.9 that ensures the integrity of structure and the full safety of population at earthquakes.
