【摘要】：援孟加拉孟中友谊展览中心地上部分总长度为228m,总宽度为78.5m,设置两道伸缩缝将主体结构分为三部分,其中两侧为展厅,中间为登陆厅。展览中心采用框架结构体系,屋顶为空间钢桁架。主要介绍该工程的项目概况、屋顶钢桁架布置和结构分析计算,着重阐述孟加拉当地地震参数的确定、特殊风荷载的确定、钢桁架屋顶采取的抗风吸措施,以及桁架下分叉柱节点设计等,并介绍了设计中关于场址选择、建筑材料选用等其他关键问题。
[Abstract]:The total length and width of the aboveground part of the Bangladesh-China Friendship Exhibition Center are 228m and 78.5m.The main body structure is divided into three parts by setting up two expansion joints, in which the exhibition hall is on both sides and the landing hall is in the middle. The exhibition center adopts a frame structure system. The roof is a space steel truss. The general situation of the project, the arrangement of roof steel truss and the analysis and calculation of structure are introduced. The determination of local seismic parameters, the determination of special wind load, and the anti-wind suction measures adopted by steel truss roof are emphasized. The design of bifurcation column joints under truss is also introduced, and other key problems in the design, such as site selection and building materials selection, are introduced.
