［摘要］上海世博會荷蘭國家館主體結(jié)構(gòu)為環(huán)繞式連續(xù)箱梁結(jié)構(gòu)。對其結(jié)構(gòu)體系及加勁肋體系進行了介紹。采用彈性支座模擬樁基以考慮基礎(chǔ)與上部結(jié)構(gòu)的共同作用；對較大扭矩作用下的箱梁結(jié)構(gòu)承載能力進行了探討；對采用X形連接板的箱梁與鋼管柱連接進行彈塑性有限元分析以驗證其承載能力及破壞機制。

［關(guān)鍵詞］世博會；環(huán)繞式連續(xù)箱梁結(jié)構(gòu)；彈性樁基支座；樁基剛度；彎扭共同作用；X形加勁肋板

Abstract:The Holland Pavilion of Expo 2010 Shanghai is a complex surrounding box-beam structure. The structure layout and the light and efficient stiffener system were mainly introduced. The innovative elastic pile support method was used, which could consider the combination action of foundation and upper structure. The bearing capacity of box-beam under large torsion moment was discussed. X-type connector was used for the box-beam and pipe column connection, and E-P FEM analysis was used to verify its bearing capacity and failure mechanism. Several important conclusions are provided for the reference of similar projects.

Keywords:Expo; surrounding continuous box-beam structure; elastic pile support; pile stiffness; combination action of bending and torsion moment; X-type stiffener
