Analysis of Bearing Capacity Influencing Factors for Tower Composite Support Frame
The tower composite support frame is a construction support system that bears vertical load,it has the characteristics of few structural parts,simple assembly,large bearing capacity and high construction efficiency.At present,in the practical engineering application process of the tower composite support frame,only the stability formula is used to simplify the calculation of the vertical bar to check the safety,and the influence of the factors such as the rotational stiffness of the joint and the initial defect can not be fully considered.By establishing the finite element model of tower composite support frame,the influence of tower height,joint rotational stiffness and initial defect on the ultimate bearing capacity of the unit tower support frame is analyzed.According to the analysis results,the corresponding control measures are put forward for the construction of the support system.
