Surveys on the Jagannath Temple's seismic response in Kathmandu

The objective of this paper is to identify the mechanisms of collapse of the Nepalese wood-masonry monuments damaged by the 2015 seismic event that struck Kathmandu and its valley. The research analyzes the case study "Jagannath Temple" located on Durbar Square in Kathmandu. After a careful anamnesis based on visual inspection and hypotheses on the temple's structural behavior local non-destructive testing (sonic, endoscopic, rebound hammer) was carried out for qualitative characterization of the structural system. These tests have been aimed at a qualitative characterization of the structural structure prior to the study of the collapse mechanisms that characterize the response to the earthquake of these monuments. Specifically, the modal analysis has allowed to characterize the soil-structure restraint while the linear dynamic analysis has highlighted the main criticalities, which characterize the historic construction.
