BACKGROUND AND POURPOSE: The need to ensure safety and security is one of the most critical priorities for humans. Awareness of the safety status of buildings can prevent many accidents and damages. This study aimed to provide an algorithm for ranking the safety of institutional buildings to implement a tool to predict institutional buildings’ safety status in operation.
METHODES: In this study a checklist was designed. In the next step, checklist items were weighted using the Fuzzy Analytic Hierarchy Process (FAHP) method. Then, the safety rating algorithm of institutional buildings was developed based on the internal relationships of criteria. In the next stage, the tools provided for the institutional building of Shahid Beheshti University of Medical Sciences were used, and its level of safety was assessed.
RESULTS: A 42-item checklist was designed based on three main criteria. Three main criteria including the "technical-service," "architectural," and "managerial" criteria gained local weights of 0.549, 0.313, and 0.136, respectively. The ranking algorithm of building safety was based on the results of weighting criteria and decision tree. Safety score of building was calibrated in a five points level from very good to very weak level. The results of safety assessment of institutional building of university using the proposed algorithm and formula showed a safety score of 13.27 and in moderate safety level.
CONCLUSION: The importance and weight of the criteria affecting the safety of the building are not the same. The items related to emergency exits and firefighting had the most impact on the safety score of in operation building. Most of the non-compliances in building safety inspection are seen in technical-service and architectural criteria.
