A Study on Escape Stairs Classification Method for openBIM-based Automated Building Code Checking

초록

With the recent increase in high-rise buildings, vertical evacuation routes are becoming more important, and stairs are a representative vertical evacuation route. In Korea, escape stair is clas- sified into three categories: ‘fire escape stairs’, ‘outdoor escape stairs’, and ‘special escape stairs’. In the classified escape stairs, different criteria for the establishment is applied depend- ing on the building condition so that human casualties can be minimized in case of a disaster. As the building becomes larger and more complex, the process of selecting and designing suit- able escape stairs is cumbersome. By using the openBIM based building code checking system, we want to automatically classify the types of escape stairs and check the appropriate criteria for the establishment. After analyzing the contents of the relevant laws and categorizing stairs according to the number of floors, use, and floor area of the building, a flowchart was pre- pared. Also, the escape stairs BIM model modeling method for checking the criteria for the establishment of fire escape stairs was proposed. By automatically classifying the types of escape stairs and checking criteria for the establishment, it is expected to reduce errors in select- ing escape stairs and help secure the safety of the vertical evacuation route.
