Abstract:Wujiang Museum is one special shaped monomer of Wujiang Exhibition Center project and adopts the structural system of reinforced concrete inclined column frame with few braces. It’s a seismic out-of-code structure. The structural system and out-of-code conditions were introduced in detail. The performance-based seismic design objectives  and out-of-code structural design measures were determined. The checking processes and methods of the key structural components were briefly introduced.  Results show that the selected structural system is rational and safe and all the structure performances can achieve respected performance-based seismic design objectives.

Keywords:Wujiang Museum; inclined column frame; structural out-of-code measure； performance-based seismic design
