Abstract:The general structure design of National Museum of China consists of two main parts, seismic reinforcement for original structure and construction for new part. The rebuilding project reserves original architectural style of museum in west and north appearances, while two new floors are added on the south part. The seismic reinforcement for old building was based on 30 years working life expectation. To appropriately connect the buildings between old and new part, a specifically designed foundation excavation program is executed to ensure the separated structures perform consistent building function. The new part is built by reinforcement concrete structure, while the steel truss is installed for large-span roof and floors, thereby, two models formed a multi-tube with part of frame structure. Depending on the analysis of foundation settlement coordination, the foundation of new constructed part is built on a piled raft system. Moreover, a series of other engineering technologies are applied in the national museum project such as: steel plate concrete composite wall, performance based seismic resistance analysis, the connecting research for node between large-span steel truss and RC structure, the vibration comfort study of large-span structure.

Keywords:National Museum of China; seismic reinforcement and reconstruction; multi-tube and sectional frame structure; steel plate concrete composite wall; comfort of floor vibration; analysis of foundation settlement coordination
