Research on the Full Life Cycle Design and Calculation of the Steel Trestle
Based on the engineering background of a steel trestle,this paper uses ANSYS finite element software to conduct a full life cycle structural analysis of the erection stage,the normal operation stage and the demolition stage.The results show that the maximum vertical deflection,the maximum stress and the maximum axial force of the rod do not appear in the operation stage.Among them,the maximum deflection appears in the erection stage,and the maximum stress and the maximum axial force both appear in the demolition stage.This shows that the operation stage is not necessarily the most unfavorable stage for the steel trestle.In order to ensure the safety of the steel trestle,the design and calculation of the full life cycle of the steel trestle should be carried out.
