Abstract: A financial plaza in Wenzhou is composed of three 100-metre-high towers and a 300-meter-long arc-shaped hull building. The hull building is connected with the tower by friction pendulum bearings，which is a huge complex high-rise conjoined structure with irregular shape. The towers adopt reinforced concrete frame-core tube structure system, and the upper circular arc hull adopts giant space steel truss structure system. This project integrates high-rise, large-span and heavy-duty structures, especially the hull giant space truss which has a great effect on temperature. Wenzhou is located in the area with high typhoon incidence, and the instantaneous maximum wind power is above grade 12.In view of the characteristics of this project, the isolation system of high-position connected long-span structure suitable for typhoon area was put forward, the design problem of coupling of earthquake, strong wind, temperature effect and so on was solved, and the safety of structure was studied, corresponding measures have been taken to strengthen it. Some key problems in structural design and corresponding treatment measures were expounded emphatically, including structural system, overall analysis, performance evaluation, key components, etc.  

Keywords:high-rise connection structure； friction pendulum bearing； giant truss； transfer floor； hull structure
