Analysis of Stress Performance of Construction Process of Phased Lifting of Tubular Trusses
The phased lifting construction method has many advantages in the installation process of tubular trusses.However,during the implementation of this construction method,the stress performance of the structure will change.Therefore,it is of great significance to analyze the stress performance of the phased lifting construction process of tubular trusses to ensure construction safety and structural stability.This article takes the large-span steel tubular truss roof as the research object,and studies and analyzes the mechanical properties of the whole lifting construction process of steel tubular trusses.Using finite element analysis software SAP2000,the stress and strain analysis under various working conditions during the lifting stage is completed,and the monitoring situation of stress and strain during the whole lifting construction is analyzed.
