Design and finite element analysis of lightweight jacking steel platform for super high-rise building

Taking the lightweight jacking steel platform used in the core tube construction of a super high-rise building as the research object, the construction principle and system design of the platform are systematically expounded, and the model of lightweight jacking steel platform is established by using finite element software ABAQUS, and the stress and displacement deformation nephogram of the jacking steel platform under four load combinations in the construction and jacking stages are obtained. The analysis shows that the maximum deformation value and stress value of the steel platform meet the specification requirements. The analysis results can provide effective data basis and technical support for the design and optimization of lightweight jacking steel platform in the future, and also provide important reference for the construction of similar projects.
