Abstract. The relationship between the design peak accelerations, the earthquake frequency and the seismological conditions of construction site for the performance based designing has been analyzed. The limitations of using the linear dependence of the repeatability logarithm on the earthquake intensity are given. Recommendations of using the new seismic scale for solving engineering problems of designing structures in seismic areas are given. It is shown that the instrumental part of the new scale is quite acceptable for the development of PBD. At the same time, in areas with the seismicity of more than 9 degrees, PGA lose their importance for assessing seismic resistance, and there is a need for rationing the input energy characteristics.

Keywords: earthquake, peak acceleration, seismic intensity scale, design standards, the period of oscillation
