Abstract:The main part of  Suzhou Xushuguan Cultural and Sports Center is a reinforced concrete frame with  partially braced tow towers, and the roof is a large-span steel roof. The two towers are connected by a north-south curved curtain wall and an atrium glass top steel grid, and the space connection is complicated. Aiming at the various irregular types of the main structure, the frame braces were reasonably arranged, and the cross-section of the beam-column members of each part of the structure was adjusted to weaken the irregularity of the structure. The performance analysis of the key components of the structure was carried out, and the stable analysis of large-span steel roof was carried out. The connection between the atrium glass top steel grid,  the curved curtain wall structure and the main structure was specially optimized. The analysis results show that the relevant design meets the seismic and safety requirements of the structure.

Keywords:irregular structure; partial braced reinforced concrete frame structure; seismic performance design; large-span steel structure
