Abstract: The plane of intemational building of Luoyang molybdenum industry is irregular. The two tower cape departments of main building have the character oflayer after layer, which belongs to the shape of resisting the earthquake disadvantage, and can easily form weak part. The solutions to unique but unfavorable architectural scheme were introduced. The west expands part of big space adopts prestressed concrete beam plank system. The foundation adopts flat panel-raft foundation after contrasting and analysis.
Keywords: building with the cape department lap over; concept design of structure; post-tensioning bonded prestressed concrete beam; flat panel-raft foundation; beam-raft foundation
