Abstract:The New Memorial Hall of War to Resist US Aggression and Aid North Korea has a very complex site, and its structural design life is 100 years. It is a special irregular structure. Based on the analysis and interpretation of the relevant code previsions, a detailed introduction was conducted on parameters valuation methods of the structure with design life of 100 years; and under engineering practices, the treatment methods of structural problems were elaborated such as foundation design in complex site, large-span concrete roof design, large cantilever structure design and connection design of old and new buildings. Besides, the analysis under fortification earthquakes and the elastic-plastic time-history analysis under rare earthquakes were supplemented against the special irregularity of the structure. Results shows that the structure can achieve the anticipated seismic precautionary objectives.

Keywords:New Memorial Hall of War to Resist US Aggression and Aid North Korea; large span structure; large cantilever structure; vertical earthquake
