Abstract:The reinforced concrete frame-shear wall system was adopted for the main structure of the reinforcement, reconstruction and engineering extension project of Exhibition Building for Military Museum of the Chinese People′s Revolution, and the main roof and the ring corridor roof of the central weapons hall adopt steel structure. Through scheme comparison, the foundation scheme and structural system were determined; in order to ensure the safety of the structure under the earthquake, the performance-based seismic analysis and design were carried out. Special measures were taken to solve the key problems of the design of large-span and heavy-loading floor, steel structural roof design, super-long structural design, foundation design close to the existing building, staggered floor treatment of basement and so on.

Keywords:Military Museum of the Chinese People′s Revolution; reinforcement and reconstruction; structural design; performance-based seismic design; large-span reinforced concrete floor; steel structural roof
