Research on the Design Method of Large Floor Multi-tower Seismic Isolation Structure
The connecting plate of the seismic isolation multi-tower series superstructure will withstand a large horizon-tal force,and the connecting plate can reliably transmit the horizontal force is an important prerequisite for the overall seismic isolation structure scheme of multiple towers,if the connecting plate is damaged or destroyed in advance,the integrity of the structure will be reduced.In order to ensure that the connecting plate should not be damaged earlier than the superstructure,this paper proposes a design method for the bearing capacity of the floor based on the main stress based on the case of seismic isolation structure of multiple towers with a large floor and multiple towers,and first uses ETABS finite element analysis software to design the seismic isolation structure of a large floor double tower,and the reinforcement design and seismic performance of the floor are calculated.Finally,according to the reinforce-ment design results,SAUSAGE nonlinear analysis software is used to analyze the damage of the floor under rare earth-quakes.The results show that after adopting the seismic isolation scheme of large floor and multiple towers,the seismic performance of the superstructure can meet the requirements of the specification,and the floor plate designed accord-ing to the main stress can meet the performance goals of each seismic level.
