1. A diagnostic method for causing a processor to execute a program stored in a memory, the diagnostic method comprising executing on the processor the steps of:
causing an inertial sensor to detect values relating to an acceleration and an angular velocity of a vibration of a building floor so as to generate a detection signal, the inertial sensor being disposed at the building floor;
calculating first vibration information related to the vibration of the building floor based on the detection signal, the first vibration information including information of frequencies and magnitudes of the vibration of the building floor;
performing a vibration diagnosis with respect to a structural body of a diagnosis model based on the calculated first vibration information, an index related to a vibration of the structural body, and information displayed on a display device, wherein the index is a standard of the vibration allowed for the structural body, and the displayed information identifies a plurality of supports that are candidates for a first support for being installed between the building floor and the structural body;
generating a second diagnosis result related to vibration damping on the structural body when the first support and a second support are installed between the building floor and the structural body, based on the second support selected based on second vibration information, the index, and information displayed on the display device, the second vibration information being related to a vibration on the structural body when the first support is installed between the building floor and the structural body;
selecting one or a plurality of supports as candidates for the second support, based on a second table and the second vibration information, the second table being for defining a correspondence between a vibration level, a value of the index, and the one or plurality of supports as the candidates for the second support;
outputting a first diagnosis result of the vibration diagnosis and the generated second diagnosis result to the display device; and
outputting information on the selected one or plurality of supports as the candidates for the second support, to the display device,
wherein the first diagnosis result includes a graph in which the index and the second vibration information are plotted.
