Abstract: No.1 Building of Wanda Plaza in Lanzhou is a high-rise residential building with a shear wall structure with super B-level in the 8th seismic intensity degree zone. The main structure has a large aspect ratio, and there are a number of general irregularities in the structure. The design ideas of the shear wall structure with a high aspect ratio were emphatically introduced. The unfavorable characteristics of the large opening on the south side of the vertical wall were analyzed in a targeted manner, and corresponding design measures were taken. Appropriate seismic design performance goals were set in light of the building function and importance, and reasonable and effective design enhancement measures were taken for each out-of-code item. Using YJK, SATWE and MIDAS/Building analysis softwares, detailed calculation and analysis were performed under different levels of seismic actions. The results show that structural indicators can meet the requirements of the three-level standard for seismic design, and the main structure can meet the requirements of seismic performance target D level.
Keywords:Wanda Plaza in Lanzhou; out-of-code high-rise structure; aspect ratio; performance-based seismic design
