Table 2: Information collection templates. The content of the template includes five categories, as follows. * \"Basic Information\" includes the date of the project, building structure, structural parameters, area, and seismic intensity. The structural parameters include, but are not limited to, the number of floors, area, length, type of floor plate, and foundation of the building. * \"Damage\" consists of \"Component Name\", \"Damage Condition\", and \"Damage Cause\"; a detailed inspection of a post-earthquake building is conducted to confirm whether the site structural layouts and dimensions of the beams and columns are consistent with the original drawings and designs.
