Abstract：
The second stress of the truss node is generated under the action of gravity or the join with other truss for the arch pipe truss with inverted triangular section, during or after the hoisting process, which leads to the displacement or instability of the truss. By using ANSYS modeling, the stress, strength and stability of the detailed model are analyzed under the enforced displacement of a given plane.The feasibility and safety of the whole lifting scheme were determined after guaranteed of bearing capacity and stability.
