Fatigue Prediction of Attached Lifting Scaffolding Guide Rails Based on Midas Gen/Abaqus

Attached lifting scaffolding is common equipment in the construction of high-rise buildings. The construction difficulty and construction risk of high-rise buildings are high. The strength of the guide rails of the attached lifting scaffolding determines the ability of the frame to withstand external loads and provides anti-overturning function. In order to improve safety in the construction process and prevent the fatigue failure of guide rails, this paper uses the finite element software Midas Gen and Abaqus combined with the fatigue life analysis software Fe-Safe to calculate the fatigue life of the guide rail based on the Goodman fatigue damage theory. The results show that fatigue occurs when the load of each layer of the scaffolding exceeds 4.7 kN/m2 rail under the construction state, considering the wind load, and the number of fatigue is 9,581,413 times. Considering the lifting state of wind load, fatigue will occur when the load of each layer of scaffolding exceeds 3.8 kN/m2, and the number of fatigues is 9,581,413 times, which can provide a reference for practical engineering.
