Simulation Analysis of Construction Stage of a High-rise Structure

In order to solve the collision, force and stability problems of a steel structure corridor in the overall lifting process, this paper takes an actual large-scale steel structure corridor project as the background, and adopts the finite element analysis software to establish two construction models for the overall lifting of the steel structure corridor, namely, constrained upper and lower cantilever beams and unconstrained upper and lower cantilever beams, and divides each construction model into synchronous lifting and unsynchronous lifting construction stages for simulation analysis. In addition, each construction model is divided into synchronous lifting and asynchronous lifting to carry out simulation analysis, and the force performance of the steel structure corridor is verified. The results show that the deformation and stress of the steel structure corridor are smaller when the upper and lower cantilever beams are restrained than when they are not restrained during the overall lifting process, and the deformation and stress are smaller when the same upper and lower cantilever beams are restrained in synchronous lifting than in non-synchronous lifting, and the reasonableness and reliability of the construction scheme are determined by finite element simulation analysis. The research results provide reference for similar steel structure corridor lifting construction simulation.
