“…This consists of the IAP for calculating the building seismic performance, and a brief explanation of the seismic risk assessment process. The new building standard (NBS) is derived on the basis of the characteristic features, such as the design year, the previous retrofitting interventions, the building importance, the fault distance, the site soil properties, and the vertical and plan irregularities integrated into the building area [78,117,[124][125][126]. The earthquake rating evaluation is given in Equation ( 12):…”

“…A building constructed in compliance with the National Building Code of Canada (NBCC) is intended to have an SPI index score of 2.0 [132]. The score obtained by using the survey classifies the seismic vulnerability classes of the buildings as "low", "medium", and "high" seismic assessment stages [126]. If the SPI value of the evaluated building is less than 10, it is classified as "low"; if it is in the range from 10 to 20, it is classified as "medium"; and if the value is more than 20, then it is classified as being of the "high" seismic vulnerability class in terms of the priority of a further detailed assessment [116,132,133].…”

Developments in the field of earthquake engineering over the past few decades have contributed to the development of new methods for evaluating the risk levels in buildings. These research methods are rapid visual screening (RVS), seismic risk indexes, and vulnerability assessments, which have been developed to assess the levels of damage in a building or its structural components. RVS methods have been proposed for the rapid pre- and/or post-earthquake screening of existing large building stock in earthquake-prone areas on the basis of sidewalk surveys. The site seismicity, the soil type, the building type, and the corresponding building characteristic features are to be separately examined, and the vulnerability level of each building can be identified by employing the RVS methods. This study describes, evaluates, and compares the findings of previous investigations that utilized conventional RVS methods within a framework. It also suggests the methods to be used for specific goals and proposes prospective enhancement strategies. Furthermore, the article discusses the time-consuming RVS methods (such as FEMA 154, which requires from 15 to 30 min, while NRCC requires one hour), and provides an overview of the application areas of the methods (pre-earthquake: FEMA 154, NRCC, NZEE, etc.; postearthquake: GNDT, EMS, etc.). This review of the traditional RVS methods offers a comprehensive guide and reference for field practitioners (e.g., engineers, architects), and recommends enhancement techniques (e.g., machine learning, fuzzy logic) for researchers to be used in future improvements.
