摘要
呼伦贝尔城市规划展览馆屋顶造型为"白云屋面",呈现出"草原上一片云"的建筑设计方案,结构形式采用双向正交桁架式网架。根据当地严寒气候条件以及屋顶独特造型,对结构各项荷载进行逐一分析,通过设置双向、单向球形铰支座释放内力,调节钢结构屋盖对下部混凝土结构的不利影响,利用SAP 2000有限元结构软件进行设计及计算,使结构经济合理,既能满足建筑造型要求,又能实现预定的性能目标。
The roof shape of Hulun Buir Urban Planning Exhibition Hall is＂the cloud on the grassland＂.The structure adopts the form of a two-way orthogonal truss.It analyzed the loads according to the local climate and the unique shape of the roof.The internal force was released by setting the two-way,one-way spherical hinge support,the negative influence of underpart concrete structure from the steel roof was adjusted.By SAP 2000,calculation and design were done to make the structure economic rationality meet the architectural requirements,and realize the performance goals.
