Abstract:New Building of Nanjing Art Museum has a unique shape, and the structure has out-of-code conditions including irregularities in plan, vertical irregularities, and large cantilevers. The structural system used in the project, technical difficulties in the design process, solutions and targeted measures were introduced. Through a variety of calculation and analysis software, special analyses were conducted of the structure, such as calculations under fortification and rare earthquakes, floor comfort analysis, prevention design of progressive collapse and joint finite element analysis. The results show that the hybrid structure of composite tube-inclined column-steel truss adopted in this project combined with architectural elements has good mechanical performance and can achieve the established seismic performance targets.
