Design analysis of complex tower crown structure of a super high-rise building
By analyzing the impact of the side opening scheme of the super high tower crown on the frame core tube super high-rise struc-ture,,and combining with wind tunnel test results,the opening scheme can effectively reduce the shape coefficient of wind load.Using the Euler formula,the slenderness ratio of spatial torsion lattice columns was determined.Finally,a detailed analysis was conducted on the seismic performance of the tower crown structure and the nodes of the steel pipe structure using SAUSAGE and MIDAS GEN finite element software;Due to the direct impact of the wind load on the tower crown on whether to add reinforcement layers to the main structure,At present,specifications and existing research for this type of project design have not yet clarified the value of wind load;The research results indicate that by opening holes in the tower crown facade,the corresponding wind load can be reduced,which is more economical for the main structure;Complex tower crown nodes have high safety,and the entire tower crown structure has higher reliability.
