“…Due to the rupture zone at this location, the maximum amount of surface non-uniform deformation caused by plastic deformation of the foundation increases the additional internal force of the upper structure. Therefore, foundation treatment and reinforcement are required at the location of the rupture [9][10][11] . when the reverse fault is mainly ruptured, the avoidance distance is 50-150m, the distance between the upper and lower plates is 3:1, and the general avoidance distance is 100m; When strike-slip rupture is the main problem, the avoidance distance of hollow brick structure (Class D) is 100-150m, the frame structure is at least 20m, and the general structure avoidance distance is 40-50m; When the normal fault is mainly ruptured, the avoidance distance is generally 50m, which can be reduced when the structural foundation is good.…”

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.

The consequences to structures caused by permanent fault displacement has been investigated for dip-slip faulting, but not for the effect of the embedment depth on the interaction between a normal fault rupture and shallow embedded foundation. This study investigated the effect of the embedment depth on the interaction of normal fault rupture and shallow foundation using a numerical model validated with centrifuge experiments. It was found that a gapping interaction mechanism and foundation distress occurred at different foundation positions relative to the fault rupture outcrop for an embedded foundation in comparison with a surface foundation. The extent of this area depended on the combined influences of the foundation position, foundation surcharge, embedment depth, and fault dip angle. The sidewalls of the shallow embedded foundation were observed to act as kinematic constraints and had considerable influence on the rotation and displacement of the foundations. With regard to the level of rotation and displacement of the embedded foundation, the lateral earth pressure distribution on the footwall sidewall was similar to that of Rankine active earth pressure in a triangular distribution and on the hangingwall sidewall as a parabolic distribution of passive earth pressure. Foundations laid on loose soil exhibited less rotation than those on dense soil because the fault ruptures were absorbed or bifurcated around both sides of the foundation.
