Abstract:Qingdao Venture Center project of the Central Academy of Fine Arts is a square-ring shape building with overlapping corners on three slopes, and frame-shear wall structure system is adopted. The main building structure has a total height of 54m and is located on three terraces slopes a height difference of about 10m between every two adjacent slopes. The structure is arranged in the way of "dropping off the floor and arranging the beams". According to the basic concepts and stress characteristics of structure on the slope, the structural treatment methods and designed difficulties of the project were introduced. Programs PKPM，MIDAS Building，SAUSAGE were used to conduct the elastic response spectrum analysis, elastic time history analysis, dynamic elastic-plastic time history analysis, and performance-based seismic design. Corresponding strengthening measures have been taken for various unfavorable factors to ensure structural safety.
Keywords:building on the slope； structure supported by foundations with different elevation； frame-shear wall structure； performance-based seismic design； strengthening measure
