The Design and Finite Element Analysis of Emergency Escape Ladder for High-Rise Building

摘要

An emergency escape ladder which is applied in emergency, for rescue and escaping is designed in this paper to meet the urge needs in modern society. As the major bearing part of the whole ladder, the ladder assembly's rigidity and strength determines the safety and reliable running of the ladder. This paper used the finite element analysis software ANSYS for nonlinear mechanics analysis of the first-section ladder, obtained the distribution diagram stress and strain, gave analysis results of the rigidity and strength, and provided an improved method and recommendations.
