Fractional Points in Engineering Seismology and Earthquake-Proof Design

详细

The article considers the possibility and necessity of using fractional points in earthquake-proof design. It is noted that in engineering seismology problems, the use of integer points is justified in estimating earthquake strength. The authors propose calling these macroseismic points. In earthquake-proof design problems, the use of fractional points becomes necessary, making it possible to differentiate impacts on buildings and structures. Three examples are considered requiring the use of fractional points: determining the calculated point score and peak accelerations for a given recurrence of impact, determining the earthquake-proof class of operating facilities, assessing seismic risk, and constructing the damage distribution density function during earthquakes.
