Abstract: In view of the large structural center-of-gravity deviation of a multi-tower connected high-rise building， the complex construction environment of the supporting trestles， and the ultra-high integral lifting， an integral lifting simulation analysis of an irregular-shaped steel connecting corridor was conducted. The lifting points of the steel connecting corridor were determined through structural static analysis， and the bearing capacity and stability of the supporting trestles were verified by finite element simulation. In addition， the structural behavior of the corridor during lifting was analyzed under two different conditions. The results showed that the stiffness， bearing capacity， and stability of the supporting trestles satisfied the specification requirements under the considered load combinations. During the synchronized lifting stage， the stress levels of the structural members remained relatively low， and the deformation complied with the specification limits. Furthermore， a double lifting point deflection correction method was shown to maintain stable stress levels in the connecting corridor during the unsynchronized lifting stage.
