Design And Analysis Of Multi-tower Connecting Structure While Connection Is Flexible Connection

The multi-tower connecting structure is one of the sleek and multi-functional usedstructure in modern architecture, the connection position is a nodus in the structural design,because the force here is more complex. The flexible connection in this thesis wouldimprove the overall seismic performance of multi-tower structure.Firstly, this thesis analyzed the simplified computational model of the flexibleconnection structure under seismic action, calculated the seismic responses and derived toa simplified formula of structure, which would calculate the bearing stiffness connectedthe main structure with the connction when they were flexible connecting. The resultsshow that the connecting structure could be the best seismic performance when theisolation bearing stiffness was0.1time of the main structure stiffness or the quality ofconnection was0.1time of the main structure.Based on these conclusions, analysisd the simplified model and the three-dimensionalmodel of two actual project, obtained the design and analysis process of the flexibleconnection with isolation bearing and researched the stiffness ratio and mass ratio of towerand corridor. Compared the analysis results between flexible connection and hingeconnection, and the results show that the former should be better for this connectingstructure, while finite element analysis basically the same conclusion with the theoreticalanalysis. Lastly, analysisd the seismic impact of the corridor to the structure of themulti-tower.
