Potential of remote sensing data to support the seismic safety assessment of reinforced concrete buildings affected by slow-moving landslides

Abstract Different forms of hazard can affect structures throughout their existence. The occurrence a seismic event in areas exposed to different risks or already affected by other phenomena is highly likely, especially countries characterized high seismicity and equally hydrogeological risk, as Italy. Nevertheless, the safety assessment reinforced concrete (RC) commonly carried out considering action only, generally applied an analytical model, neglecting stress–strain state induced previous ongoing phenomena. aim this work highlight importance multi-hazard analysis, cumulating coming from two hazards: landslide earthquake. An existing RC building, located area intermittent phenomenon with slow kinematics, that may also be subjected strong earthquakes, used case study. Differential Synthetic Aperture Radar Interferometry (DInSAR) approach monitor evolution time landslide. DInSAR deformation data are detect surface ground movements building foundations. A non-linear static analysis procedure implemented for code-based assessment, scenarios. case-study condition structure deformed only gravity loads, and, then, known landslide-induced configuration. comparison proposed between performed both cases, without consideration displacements, showing evaluation.
