上海世博会荷兰国家馆主体结构为环绕式连续箱梁结构。对其结构体系及加劲肋体系进行了介绍。采用弹性支座模拟桩基以考虑基础与上部结构的共同作用;对较大扭矩作用下的箱梁结构承载能力进行了探讨;对采用X形连接板的箱梁与钢管柱连接进行弹塑性有限元分析以验证其承载能力及破坏机制。 The main structure of the Dutch Pavilion at Shanghai Expo is a wraparound continuous box girder structure. The structural system and stiffener system are introduced. The elastic abutments are used to simulate the pile foundation to consider the interaction between the foundation and the superstructure. The bearing capacity of the box girder under high torque is discussed. The elastoplasticity of box girders and steel columns connected by X-shaped connecting plates Meta-analysis to verify its carrying capacity and destruction mechanism.
