In this paper, we analyzed the safety on static and dynamic characteristics of a top-down evacuation instrument fixed on the exterior walls of a building using finite element analysis. For this purpose, the stress distribution characteristics of the H-beam structure were analyzed and the equivalent stress distribution, deflection displacement and natural frequency characteristics of the overall structure of the evacuation instrument were analyzed. The structures were applied with the materials of SS440 and SUS304. The static analysis results showed the elastic behavior with safety coefficients from 2.4 to 2.9, by confirming the structural safety. In addition, the analysis of the natural frequency characteristics confirmed that the vibration characteristics were higher than the external conditions of 20Hz.
