The invention provides a safety diagnosis system for structure, which comprises one GNSS receiver installed on an upper floor of a structure, a control device having a storage unit for storing a program which prepares an absolute displacement curve of the structure based on an absolute coordinate measured by the GNSS receiver and a displacement of the absolute coordinate, calculates a maximum inter-layer displacement and a maximum inter-layer deformation angle per each floor based on the absolute displacement curve and prepares an inter-layer deformation angle curve and a judging unit for performing a diagnosis of the safety of the structure based on the maximum inter-layer displacement and the maximum inter-layer deformation angle, and a display unit, wherein the control device calculates the maximum inter-layer displacement and the maximum inter-layer deformation angle per each floor and the inter-layer deformation angle curve based on a displacement of the absolute coordinate and the program and makes the display unit display a diagnosis result of the structure as evaluated by the judging unit based on at least one of the maximum inter-layer displacement and the maximum inter-layer deformation angle or the inter-layer deformation angle curve.
