Abstract:Tower 1# for Rizhao Haiyun Plaza has the large roof structural height of 369m and the building tower crown height of 390m. There are 4 floors underground, and 86 floors above ground. It belongs to a super high-rise out-of-code building. The structure adopts the structural system of round steel tube concrete frame column + steel beam-reinforced concrete corewall + strengthened story with outrigger truss. The corewall is partially indented on the 77th floor. There are six irregular items in the tower, such as local slab discontinuity, sudden stiffness, sudden change in bearing capacity, jump column, height overrun, and strengthened story. Aiming at irregular projects and combining with the opinions of experts from the National Overrun Review Committee for several times, the seismic performance targets of each component were determined. According to the seismic performance targets, the calculation of the seismic shear force undertaken by the frame and the out-of-plane calculation of the indentation wall of the corewall section and comfort calculation under wind load. The results show that the structure can meet the relevant indexes under the action of vertical load and wind load, and the seismic performance can reach the set performance target.

Keywords:Rizhao Haiyun Plaza; super high-rise building; mixed structure; strengthened story; corewall indentation; structural seismic design
