The north and South towers are placed by certain angle, and it designed for the adjustment of plane with layout of shear wall near two tower dynamic characteristics. For the complexity of connection system, the performance of different design goals are worked out for connecting different parts of body as well as the tower. According to the calculation results and to take measures to strengthen the connection body, the connection system can achieve the design target. It ensures the safety and reliability of the whole structure.

Keywords: Strong connection structure, the performance design objective, twin towers.
