In the fatigue life assessment of adjustable telescopic steel prop joints subjected to cyclic loading is critical for determining the number of cycles before fatigue failure of 235GT steel materials. The research aims in this reported work were to develop a computational material model and 3D finite-element analysis model to accurately predict the static and dynamic cyclic load-deformation characteristics of 235GT steel and adjustable telescopic steel prop components. Critical values for stress components, responsible for distinctive fatigue failure of the adjustable telescopic steel prop were obtained and the fatigue limits were illustrated in the Smith diagram. To achieve these, finite element analysis were employed to calculate compressive stresses and equivalent Von Mises stresses as well as the analysis by the strength of materials experimental procedure in laboratory conditions. Hence, through appropriate computer software, the fatigue strength of adjustable telescopic steel prop was automatically determined and expressed in the form of the Smith diagram. The results obtained by the finite-element analysis and calculations are entirely similar to that of strength of materials procedure. This research helps improving site safety to understand the current working load limit basis for the material design of adjustable telescopic steel prop structures and make this design risk-consistent to prevent fatal injuries in the building construction industry.
