Abstract:Tower A and tower B of Linyi China Resources Center project are double-tower out-of-code high-rise buildings with different structural systems under the large chassis in the high seismic fortification intensity region. Tower A adopts the frame-corewall structural system, and tower B adopts the frame-shear wall structural system. The envelope size of the podium is 88m×94m, with 4 irregularities in the structure. According to the structural system characteristics of this project, the reliability of structural design was guaranteed by adopting reasonable seismic performance-based design objectives and methods, strengthening the design of key components and other measures. The mechanical characteristics of the side frame beam and the frame beam  of the high-rise frame-corewall structure in the high seismic fortification intensity region were summarized, and the reinforcement was configured according to the mechanical characteristics. At the same time, through the calculation under fortification earthquake, measures were taken to prevent the cracking of the podium floors. After calculation and review, the seismic performance targets of structure meet the requirement of grade C, and the structure is safe and reliable.
