The unsymmetrical double towers linked with connective strcuture often adopts the weak connection form when the position of the connector is not high,and the selection of the connector support has a great influence on the force of the two sides of the structure.The dynamic characteristics of the tower main structure under different weak connection methods of the connectors and the seismic performance of the key members of the main structure under rare earthquakes were analyzed comparatively,and the comfort analysis of slabs on connecter was carried out.The results show that even if the weak connection is adopted,the closer the volume and height of the connector is to the tower monolith,the more obvious is the constraint effect of the connector on the tower.The bidirectional friction pendulum bearing scheme at both ends of the connector is better than the scheme with one end fixed hinged support and one end bidirectional friction pendulum bearing scheme.Under rare earthquakes,the interstorey displacement angle of the floors at the connector and at the lower connector with bidrectional friction pendulum bearing scheme is the smallest among the different schemes,and the key components can achieve a higher level of performance.The use of bidrectional friction pendulum bearing scheme results in large horizontal displacement of the support,and measures need to be taken in the design to ensure that the connectors do not dislodge during rare earthquakes.For multi-storey towers linked with connective strcuture with different architectural functions,the peak vertical acceleration of each floor slab can be reduced more effectively by increasing floor thickness to meet comfort requirements of floor.
