克拉玛依市科技博物展览馆结构设计及关键技术

Structure design and key techniques of Science and Technology Museum in Karamay

新疆克拉玛依市科技博物展览馆是一个平面、立面不规则的超限高层连体的重要建筑。主体塔楼结构及附属大体积混凝土块体构筑物采用预应力钢筋混凝土大跨度倾斜框架-剪力墙结构,连体及球幕采用钢结构。针对这种复杂、特殊的结构体系,制定了抗震性能指标,基于多种有限元软件进行结构设计整体协同分析。结构设计中运用了复杂块体有限元总装分析技术、高支模设计施工一体化技术、缓粘结预应力技术等。

As a high-rise connected building,the exhibition hall of Science and Technology Museum in Karamay,Xinjiang Province,has irregular plans and facades,which lead the whole structure system to exceed the codes on several aspects.The main tower and its attached large-volume concrete-blocked structure are large-span inclined frame-shear wall system,as well as the connection parts and spherical screen are steel structures.Seismic performance objectives of the complex structure were presented.And the whole structural design was performed by several software.The implementations of some uncommon techniques in this design were presented,such as FE-assembling of complicate blocks,integration of design and construction of high-formwork,slow connecting in presressing,etc.
