Abstract

The damage and setback distance of nearby buildings caused by strong earthquake surface rupture is one of the hot topics in the relationship between earthquake engineers, structural designers, and geotechnical earthquake geology experts. This article provides recommended values for setback distance under reverse, normal, and strike slip faults through the discussion and analysis of seismic damage to structures on the distribution trace of surface ruptures and adjacent areas. At the same time, for structures near surface ruptures, if seismic measures for the cover layer and foundation under the effect of surface ruptures are considered or strengthened, and the basic setback distance is about 30-50m. This provides an important data source and basis for revision of the active fault setback distance in seismic code.
