Abstract: The structural systems of two towers of China General Nuclear Power Group building are introduced as well as design characteristics. Above the 10th floor of the North Tower, there is a steel suspending structure of 16.5m span and steel reinforced concrete columns attached to it. Design procedure are emphatically introduced, including structural system selection, calculation method, optimization of structural system, construction measures and energy dissipation analysis of long span suspending structure. It provides useful design experience for the same kind projects.

Keywords: performance-based seismic design; suspending truss; energy dissipation
