| Abstract | The Level 2 – SQST adopts a methodology based on exterior and interior visual screening of buildings using the Level 2 – SQST screening forms completed by trained screeners with basic knowledge in seismic design and assessment of buildings. The Level 2 – SQST screening forms provide space for documenting collected data. Based on collected building information in office and site visits, structural and non-structural component scores are calculated to estimate the expected seismic risk of buildings. Structural and non-structural component scores are compared with corresponding thresholds to determine whether the seismic risk posed by structural and non-structural components is acceptable. Given this, the building owner is expected to assume the level of risk associated with the structural and non-structural component scores. Buildings identified as potentially hazardous are flagged for seismic evaluation. The Level 2 – SQST also identifies special conditions that immediately trigger seismic evaluation. These conditions are (1) unknown model building type, (2) federal heritage designation, (3) change of occupancy results in increase of structural loads, (4) current consequences of failure higher than original consequences of failure, (5) Site Class F, (6) presence of geologic hazards, and (7) significant building deterioration or damage. The Level 2 – SQST can also be used for prioritizing buildings requiring seismic evaluation. Buildings that are spread over a large region or across the country can be ranked based on the structural and non-structural component prioritization indexes that are functions of structural and non-structural scores and consequences of failure of the buildings. Furthermore, the ranking can be used to develop building inventories for regional and national earthquake damage and loss assessment. |
